cisco设置

cisco设置连接1.用Cisco 2600路由器自带的一条串行电缆将路由器的Console口与1台运算机串口相连。

2.启动Windows 2000后，执行以下操作：“开始→程序→附件→通讯→超级终端”，在“连接描述”对话框的名称一栏中输入超级终端名，运行Hypertrm.exe，点击“确定”。

3.在“连接到”窗体中的“连接时使用”栏选择“COM1”，单击确定。

在弹出的“COM1属性”窗体中进行端口设置。

设置终止，打开路由器电源，就会显现路由器的启动信息。

这时就能够像在终端一样对路由器进行操作了。

配置路由器的配置操作都必须连接到路由器的终端上，在Cisco路由器操作系统IOS的提示符下进行操作。

常用配置方法如下：配置以太网络接口的IP地址Router> enable '进入特权模式Password：'特权用户口令Router# configure terminal '进入配置模式Enter configuration commands one per line. End with CNTL/Z.Routerconfig# interface Ethernet 0 '进入外部以太网口配置Routerconfig-if# ip address 192.168.0.11 255.255.255.0 '进入AUI0接口的IP地址配置为192.168.0.11，子网掩码为255.255.255.0。

配置静态路由表Router> enablePassword：Router# config terminalEnter configuration commands one per line. End with CNTL/Z.Routerconfig# ip route 192.168.2.0 255.255.255.0 192.168.0.1 '配置进入AUI0接口的IP地址。

cisco双线双路网络路由器怎么设置

cisco双线双路网络路由器怎么设置思科cisco是全球领先且顶尖的通讯厂商，出产的路由器功能也是很出色的，那么你知道cisco双线双路网络路由器怎么设置吗?下面是店铺整理的一些关于cisco双线双路网络路由器怎么设置的相关资料，供你参考。

cisco双线双路网络路由器设置一，路由策略的优势：经常关注我们IT168网络频道的读者都知道之前我们介绍过如何从本地计算机的路由信息入手解决这种双线双路的实际网络问题，然而该方法只限于在单台计算机上操作，如果企业的员工计算机非常多，一台一台机器的设置肯定不太现实，这时我们就可以通过路由策略实现对企业网络路由器设置出口的统筹管理，将出口网络路由器设置合理的路由策略，从而让网络数据包可以根据不同需求转发到不同的线路。

总体说来路由策略各个命令只需要我们在企业连接网络外部出口的网络路由器设置即可，该路由器实际连接的是双线双路，即一个接口连接通往中国网通的网络，一个接口连接抵达中国电信的网络。

cisco双线双路网络路由器设置二，路由策略命令简单讲解：路由策略的意义在于他可以让路由器根据一定的规则选择下一跳路由信息，这样就可以自动的根据接收来的网络数据包的基本信息，判断其应该按照哪个路由表中的信息进行转发了。

通过路由策略我们可以为一台路由器指定多个下一跳转发路由地址。

下面我们来看一段路由策略指令，然后根据其后面的指示信息来了解他的意义。

(1)路由策略基本信息的设置：route-map src80 permit 10//建立一个策略路由，名字为src80，序号为10，规则为容许。

match ip address 151//设置match满足条件，意思是只有满足ip address符合访问控制列表151中规定的才进行后面的set操作，否则直接跳过。

set ip next-hop 10.91.31.254//满足上面条件的话就将这些数据的下一跳路由信息修改为10.91.31.254。

cisco路由器完整版配置大全

CISCO路由器设置完全手册文章主要分析了路由器设置方面的一些技巧，同时讲解了在使用BT/PPLive一些注意的要点，很多人都喜欢看网络电视，但是也会出现很多问题。

如何正确的进行路由器设置，是用户最为关心的问题，可能好多人还不了解如何在家庭使用中将路由器设置到最佳，没有关系，看完本文你肯定有不少收获，希望本文能教会你更多东西。

使用路由器设置共享上网后，在进行BT下载，收看PPLive视频时很多网友反应通过路由器设置无法进行BT下载，或者下载速度与PC直接连接网络时的下载相比甚慢，PPLive 也出现了同样的问题。

下文我们将以网件WGR614v7无线路由为例对二者剖析释疑，并给予解决之法或有效建议。

BT下载速度的快慢主要取决于BT的监听端口是否映射成功，该参数是可以在BT工具中自定义的。

监听端口若映射不成功将严重影响下载速率，种子数量极少的文件则可能完全无法下载，种子数量多的下载速率亦不会很快。

但经测试，BitComet的UPnP与WGR614v7(固件：V1.0.14/V1.3.16)的UPnP存在兼容性问题，最近出的最新版0.84亦不例外，而BitSpirit最新版3.2.2.215则能与路由器设置很好地协同工作，强烈推荐WGR614v7的用户使用。

以下行2M上行512K的ADSL为例，对应的最大下载上传速率分别为256KB/S和64KB/S，若BT的传输数据占用了所有带宽，那么不仅会使得其他应用无法正常使用，BT下载亦会受到影响，那是由于除传输数据以外，BT还有控制信息亦同时在传送，以此保证该应用的正常进行。

ADSL亦有通讯信息不断发送，保证宽带的正常连接。

因此强烈建议ADSL用户设置下载和上传的上限。

若内网有不止一个用户使用BT工具，那么需要注意BT的监听端口不要相同，且最好都设置下载上传上限，合理的带宽分配使各人的下载都得到保证。

即使无其他特别应用，所有PC的总的下载上传上限值亦尽量不要超过宽带最大带宽的80%。

Cisco路由器的调试和配置

Cisco路由器的调试和配置Cisco路由器是一种非常常用和重要的网络设备，用于实现网络的连接、安全性和数据传输。

路由器的调试和配置是保证网络正常运行和安全性的重要环节。

本文将介绍Cisco路由器的调试和配置的基本知识和步骤。

一、Cisco路由器的调试1. 确定问题：在进行路由器调试之前，首先要确定问题所在。

可以通过网络的错误报告、用户的反馈以及某些网络测试工具等来分析问题，并在调试过程中持续监测和排查。

2. 登录路由器：通过终端或远程连接方式登录到路由器的命令行界面。

输入正确的用户名和密码，并进入特权模式。

3. 开启调试模式：输入命令“debug”来开启调试模式。

可以使用“debug all”命令来开启所有的调试功能，也可以使用具体的调试功能命令来针对性地进行调试。

4. 监测和分析：在调试模式下，可以通过显示和分析路由器的调试输出信息来排查问题。

可以使用命令“show”来查看和比较不同的网络状态和配置信息。

5. 停止调试：当问题排查完毕后，应使用“undebug all”命令来关闭所有的调试功能，以避免对路由器的正常工作造成影响。

二、Cisco路由器的配置1. 登录路由器：同样，通过终端或远程连接方式登录到路由器的命令行界面。

输入正确的用户名和密码，并进入特权模式。

2. 进入全局配置模式：在命令行界面中输入“configure terminal”命令，进入全局配置模式。

在全局配置模式下，可以对路由器的各项配置进行修改和优化。

3. 配置主机名：通过命令“hostname”来配置路由器的主机名。

主机名应具有辨识度，并符合命名规范。

4. 配置接口：使用命令“interface”来配置路由器的各个接口。

通过这些接口，路由器可以与其他网络设备进行通信。

可以设置接口的IP地址、子网掩码、MTU（最大传输单元）等。

5. 配置路由协议：使用命令“router”来配置路由器的路由协议。

不同的路由协议有不同的特点和适用范围，可以根据实际需求来选择并配置适当的路由协议。

ACLs are used to block IP packets from being forwarded by a router.RFC 1858 covers security considerations for IP fragment filtering and highlights two attacks on hosts that involve IP fragments of TCP packets, the Tiny Fragment Attack and the Overlapping Fragment Attack. Blocking these attacks is desirable because they can compromise a host, or tie up all of its internal resources.RFC 1858 also describes two methods of defending against these attacks, the direct and the indirect. In the direct method, initial fragments that are smaller than a minimum length are discarded. The indirect method involves discarding the second fragment of a fragment set, if it starts 8 bytes into the original IP datagram. Please see RFC 1858 for more details.Traditionally, packet filters like ACLs are applied to the non−fragments and the initial fragment of an IP packet because they contain both Layer 3 and 4 information that the ACLs can match against for a permit or deny decision. Non−initial fragments are traditionally allowed through the ACL because they can be blocked based on Layer 3 information in the packets; however, because these packets do not contain Layer 4 information, they do not match the Layer 4 information in the ACL entry, if it exists. Allowing the non−initial fragments of an IP datagram through is acceptable because the host receiving the fragments is not able to reassemble the original IP datagram without the initial fragment.Firewalls can also be used to block packets by maintaining a table of packet fragments indexed by source and destination IP address, protocol, and IP ID. Both the Cisco PIX Firewall and the Cisco IOS® Firewall can filter all the fragments of a particular flow by maintaining this table of information, but it is too expensive to do this on a router for basic ACL functionality. A firewall's primary job is to block packets, and its secondary role is to route packets; a router's primary job is to route packets, and its secondary role is to block them. Two changes were made in Cisco IOS Software Releases 12.1(2) and 12.0(11) to address some security issues surrounding TCP fragments. The indirect method, as described in RFC 1858 , was implemented as part of the standard TCP/IP input packet sanity checking. Changes were also made to ACL functionality with respect to non−initial fragments.Types of ACL EntriesThere are six different types of ACL lines, and each has a consequence if a packet does or does not match. In the following list, FO = 0 indicates a non−fragment or an initial fragment in a TCP flow, FO > 0 indicates that the packet is a non−initial fragment, L3 means Layer 3, and L4 means Layer 4.Note: When there is both Layer 3 and Layer 4 information in the ACL line and the fragments keyword is present, the ACL action is conservative for both permit and deny actions. The actions are conservative because you do not want to accidentally deny a fragmented portion of a flow because the fragments do not contain sufficient information to match all of the filter attributes. In the deny case, instead of denying anon−initial fragment, the next ACL entry is processed. In the permit case, it is assumed that the Layer 4 information in the packet, if available, matches the Layer 4 information in the ACL line.Permit ACL line with L3 information onlyIf a packet's L3 information matches the L3 information in the ACL line, it is permitted.1.2.If a packet's L3 information does not match the L3 information in the ACL line, the next ACL entry is processed.Deny ACL line with L3 information onlyIf a packet's L3 information matches the L3 information in the ACL line, it is denied.1.2.If a packet's L3 information does not match the L3 information in the ACL line, the next ACL entry is processed.Permit ACL line with L3 information only, and the fragments keyword is presentIf a packet's L3 information matches the L3 information in the ACL line, the packet's fragment offset is checked.a.If a packet's FO > 0, the packet is permitted.b.If a packet's FO = 0 , the next ACL entry is processed.Deny ACL line with L3 information only, and the fragments keyword is presentIf a packet's L3 information does match the L3 information in the ACL line, the packet's fragment offset is checked.If a packet's FO > 0, the packet is denied.a.b.If a packet's FO = 0, the next ACL line is processed.Permit ACL line with L3 and L4 information1.If a packet's L3 and L4 information matches the ACL line and FO = 0, the packet is permitted.2.If a packet's L3 information matches the ACL line and FO > 0, the packet is permitted.Deny ACL line with L3 and L4 information1.If a packet's L3 and L4 information matches the ACL entry and FO = 0, the packet is denied.2.If a packet's L3 information matches the ACL line and FO > 0, the next ACL entry is processed.ACL Rules FlowchartThe following flowchart illustrates the ACL rules when non−fragments, initial fragments, and non−initial fragments are checked against the ACL.Note: The non−initial fragments themselves contain only Layer 3, never Layer 4 information, although the ACL may contain both Layer 3 and Layer 4 information.How Packets Can Match an ACLExample 1The following five possible scenarios involve different types of packets encountering ACL 100. Please refer to the table and flow chart as you follow what happens in each situation. The IP address of the web server is 171.16.23.1.access−list 100 permit tcp any host 171.16.23.1 eq 80access−list 100 deny ip any anyThe packet is an initial fragment or a non−fragment destined for the server on port 80:The first line of the ACL contains both Layer 3 and Layer 4 information, which matches the Layer 3 and Layer 4 information in the packet, so the packet is permitted.The packet is an initial fragment or a non−fragment destined for the server on port 21:1.The first line of the ACL contains both Layer 3 and Layer 4 information, but the Layer 4 information in the ACL does not match the packet, so the next ACL line is processed.2.The second line of the ACL denies all packets, so the packet is denied.The packet is a non−initial fragment to the server in a port 80 flow:The first line of the ACL contains Layer 3 and Layer 4 information, the Layer 3 information in the ACL matches the packet, and the ACL action is to permit, so the packet is permitted.The packet is a non−initial fragment to the server in a port 21 flow:The first line of the ACL contains both Layer 3 and Layer 4 information. The Layer 3 information in the ACL matches the packet, there is no Layer 4 information in the packet, and the ACL action is to permit, so the packet is permitted.The packet is an initial fragment, non−fragment or non−initial fragment to another host on the server subnet:1.The first line of the ACL contains Layer 3 information that does not match the Layer 3 information in the packet (the destination address), so the next ACL line is processed.2.The second line of the ACL denies all packets, so the packet is denied.Example 2The following same five possible scenarios involve different types of packets encountering ACL 101. Again, please refer to the table and flow chart as you follow what happens in each situation. The IP address of the web server is 171.16.23.1.access−list 101 deny ip any host 171.16.23.1 fragmentsaccess−list 101 permit tcp any host 171.16.23.1 eq 80access−list 101 deny ip any anyThe packet is an initial fragment or non−fragment destined for the server on port 80:The first line of the ACL contains Layer 3 information which matches the Layer 3 information in the1.packet. The ACL action is to deny, but because the fragments keyword is present, the next ACLentry is processed.2.The second line of the ACL contains Layer 3 and Layer 4 information, which matches the packet, so the packet is permitted.The packet is an initial fragment or non−fragment destined for the server on port 21:1.The first line of the ACL contains Layer 3 information, which matches the packet, but the ACL entry also has the fragments keyword, which doesn't match the packet because FO = 0, so the next ACLentry is processed.The second line of the ACL contains Layer 3 and Layer 4 information. In this case, the Layer 42.information does not match, so the next ACL entry is processed.3.The third line of the ACL denies all packets, so the packet is deniedThe packet is a non−initial fragment to the server in a port 80 flow:The first line of the ACL contains Layer 3 information which matches the Layer 3 information in the packet. Remember that even though this is part of a port 80 flow, there is no Layer 4 information in the non−initial fragment. The packet is denied because the Layer 3 information matches.The packet is a non−initial fragment to the server in a port 21 flow:The first line of the ACL contains Layer 3 information only, and it matches the packet, so the packet is denied.The packet is an initial fragment, non−fragment or non−initial fragment to another host on the server subnet:1.The first line of the ACL contains Layer 3 information only, and it does not match the packet, so the next ACL line is processed.2.The second line of the ACL contains Layer 3 and Layer 4 information. The Layer 4 information in the packet does not match that of the ACL, so the next ACL line is processed.3.The third line of the ACL denies this packetfragments Keyword ScenariosScenario 1Router B connects to a web server, and the network administrator does not want to allow any fragments to reach the server. This scenario shows what happens if the network administrator implements ACL 100 versus ACL 101. The ACL is applied inbound on the routers Serial0 (s0) interface and should allow onlynon−fragmented packets to reach the web server. See the ACL Rules Flowchart and the How Packets Can Match an ACL sections as you follow the scenario.Consequences of Using the fragments KeywordThe following is ACL 100:access−list 100 permit tcp any host 171.16.23.1 eq 80access−list 100 deny ip any anyThe first line of the ACL 100 allows only HTTP to the server, but it also permits non−initial fragments to any TCP port on the server. It permits these packets because non−initial fragments do not contain Layer 4 information, and the ACL logic assumes that if the Layer 3 information matches, then the Layer 4 information would also match, if it was available. The second line is implicit and denies all other traffic.It is important to note that, as of Cisco IOS Software Releases 12.1(2) and 12.0(11), the new ACL code drops fragments that do not match any other line in the ACL. Earlier releases allow non−initial fragments through if they do not match any other line of the ACL.The following is ACL 101:access−list 101 deny ip any host 171.16.23.1 fragmentsaccess−list 101 permit tcp any host 171.16.23.1 eq 80access−list 101 deny ip any anyACL 101 does not allow non−initial fragments through to the server because of the first line. A non−initial fragment to the server is denied when it encounters the first ACL line because the Layer 3 information in the packet matches the Layer 3 information in the ACL line.Initial or non−fragments to port 80 on the server also match the first line of the ACL for Layer 3 information, but because the fragments keyword is present, the next ACL entry (the second line) is processed. The second line of the ACL permits the initial or non−fragments because they match the ACL line for Layer 3 and Layer 4 information.Non−initial fragments destined to the TCP ports of other hosts on the 171.16.23.0 network are blocked by this ACL. The Layer 3 information in these packets does not match the Layer 3 information in the first ACL line, so the next ACL line is processed. The Layer 3 information in these packets does not match the Layer 3 information in the second ACL line either, so the third ACL line is processed. The third line is implicit and denies all traffic.The network administrator in this scenario decides to implement ACL 101 because it permits onlynon−fragmented HTTP flows to the server.Scenario 2A customer has Internet connectivity at two different sites, and there is also a backdoor connection between the two sites. The network administrator's policy is to allow Group A in Site 1 to access the HTTP server atSite 2. The routers at both sites are using private addresses (RFC 1918 ) and Network Address Translation (NAT) to translate packets that are routed through the Internet.The network administrator at Site 1 is policy−routing the private addresses assigned to Group A, so that they use the backdoor through Router A's Serial0 (s0) when accessing the HTTP server at Site 2. The router at Site 2 has a static route to 172.16.10.0, so that return traffic to Group A is also routed through the backdoor. All other traffic is processed by NAT and routed through the Internet. The network administrator in this scenario has to decide which application or flow is going to work if the packets are fragmented. It is not possible to make both the HTTP and File Transfer Protocol (FTP) flows work at the same time because one or the other breaks.See the ACL Rules Flowchart and the How Packets Can Match an ACL sections as you follow the scenario. Explanation of the Network Administrator's OptionsIn the following example, the route map called FOO on Router A sends packets that match ACL 100 across to Router B through s0. All packets that do not match are processed by NAT and take the default route through the Internet.Note: If a packet falls off the bottom of the ACL, or is denied by it, then it is not policy−routed.The following is a partial configuration of Router A, showing that a policy route−map called FOO is applied to interface e0, where the traffic from Group A enters the router:hostname Router_Aint e0ip policy route−map FOOroute−map FOO permit 10match ip address 100set ip next−hop 10.1.1.2access−list 100 permit tcp 172.16.10.0 0.0.0.255 host 192.168.10.1 eq 80access−list 100 deny ip any anyACL 100 allows policy routing on both initial, non−fragments and non−initial fragments of HTTP flows to the server. Initial and non−fragments of HTTP flows to the server are permitted by the ACL and policy routed because they match the Layer 3 and Layer 4 information in the first ACL line. Non−initial fragments are permitted by the ACL and policy routed because the Layer 3 information in the packet also matches the firstACL line; the ACL logic assumes that the Layer 4 information in the packet would also match if it was available.Note: ACL 100 breaks other types of fragmented TCP flows between Group A and the server because the initial and non−initial fragments get to the server through different paths; the initial fragments are processed by NAT and routed through the Internet, but the non−initial fragments of the same flow are policy routed.A fragmented FTP flow helps illustrate the problem in this scenario. The initial fragments of an FTP flow match the Layer 3 information, but not the Layer 4 information, of the first ACL line, and they are subsequently denied by the second line. These packets are processed by NAT and routed through the Internet. The non−initial fragments of an FTP flow match the Layer 3 information in the first ACL line, and the ACL logic assumes a positive match on Layer 4 information. These packets are policy routed, and the host reassembling these packets does not recognize the initial fragments as part of the same flow as thepolicy−routed non−initial fragments because NAT has changed the source address of the initial fragments. ACL 100 in the configuration below fixes the FTP problem. The first line of ACL 100 denies both initial and non−initial FTP fragments from Group A to the server.hostname Router_Aint e0ip policy route−map FOOroute−map FOO permit 10match ip address 100set ip next−hop 10.1.1.2access−list 100 deny tcp 172.16.10.0 0.0.0.255 host 192.168.10.1 fragmentsaccess−list 100 permit tcp 172.16.10.0 0.0.0.255 host 192.168.10.1 eq 80access−list 100 deny ip any anyInitial fragments match on the Layer 3 information in the first ACL line, but the presence of the fragments keyword causes the next ACL line to be processed. The initial fragment does not match the second ACL line for Layer 4 information, and so the next implicit line of the ACL is processed, which denies the packet.Non−initial fragments match the Layer 3 information in the first line of the ACL, so they are denied. Both initial and non−initial fragments are processed by NAT and routed through the Internet, so the server has no problem with reassembly.Fixing FTP flows breaks fragmented HTTP flows because the initial HTTP fragments are now policy routed, but the non−initial fragments are processed by NAT and routed through the Internet.When an initial fragment of an HTTP flow from Group A to the server encounters the first line of the ACL, it matches on the Layer 3 information in the ACL, but because of the fragments keyword, the next line of the ACL is processed. The second line of the ACL permits and policy routes the packet to the server.When non−initial HTTP fragments destined from Group A to the server encounters the first line of the ACL, the Layer 3 information in the packet matches the ACL line and the packet is denied. These packets are processed by NAT and traverse the Internet to get to the server.The first ACL in this scenario allows fragmented HTTP flows and breaks fragmented FTP flows. The second ACL allows fragmented FTP flows and breaks fragmented HTTP flows. The TCP flows break in each case because the initial and non−initial fragments take different paths to the server. Reassembly is not possible because NAT has changed the source address of the non−initial fragments.It is not possible to construct an ACL that allows both kinds of fragmented flows to the server, so the network administrator has to choose which flow he wants to work.Related InformationConfiguring Access Control Lists••IP Routing Support PageTechnical Support − Cisco Systems•All contents are Copyright © 1992−2005 Cisco Systems, Inc.

The included device manager software provides an intuitive, web-based interface to simplify setup, security, and quality of service (QoS) traffic prioritization, allowing even users without IT expertise to configure the switch in minutes. Cisco also provides a Cisco FindIT Network Discovery Utility. This utility that works through a simple toolbar on the user’s web browser to discover Cisco devices in the network and display basic information, such as serial numbers and IP addresses, to aid in the configuration and deployment of Cisco Small Business products. For more information, and to download the utility, please visit /go/findit.These switches use Cisco Discovery Protocol as well as Link Layer Discovery Protocol (LLDP-MED) to automatically detect all the devices connected to your network, and then automatically configure themselves for the appropriate connectivity and instructs the devices to use appropriate voice VLAN orQoS parameters. For more advanced capabilities and hands-on control, the switches supportSmartport roles which configure the ports with specific levels of Security, QoS, and availabilityaccording to the type of connected device, based on Cisco best practices and pretested configurations.The Auto Smartports feature applies the intelligence delivered through the Smartport roles and applies it automatically to the port based on the devices discovered over CDP or LLDP-MED. This facilitates zero touch deployments. Although the Cisco 300 Series is designed to be deployed without using a command-line interface (CLI), Cisco Textview is available for those who prefer to use text-based configuration. Together, these features reduce the time your staff must devote to network deployment, management, and troubleshooting.●Strong security: The Cisco 300 Series Switches provide a high level of security and give you fine-grained control to safeguard your network from unauthorized users. Advanced security featuresinclude:◦Embedded security to protect management data traveling to and from the switch and encrypt network communications.◦Extensive access control lists (ACLs) to restrict sensitive portions of the network from unauthorized users and guard against network attacks.◦Guest virtual LANs (VLANs) to let you provide Internet connectivity to nonemployee users while isolating critical business services from guest traffic.◦Support for advanced network security applications such as IEEE 802.1X port security to tightly limit access to specific segments of your network. Web based authentication provides a consistentinterface to authenticate all types of host devices and operating systems, without the complexity of deploying IEEE 802.1X clients on each endpoint.◦Time based ACLs and Port Operation restrict access to the network during predesignated times, such as business hours.◦Security mechanisms such as, Bridge Protocol Data Unit (BPDU) Guard andbroadcast/multicast/unknown unicast storm control, protect the network from invalid configurations or malicious intent.◦Secure Core Technology (SCT) helps ensure that the switch will receive and process management and protocol traffic no matter how much traffic is received.◦Advanced defense mechanisms, including Dynamic ARP Inspection (DAI), IP Source Guard, and Dynamic Host Configuration Protocol (DHCP) snooping, detect and block deliberate network attacks.Combinations of these protocols are also referred to as IPMB (IP-MAC-port binding).◦IPv6 First Hop Security extends the advanced threat protection to IPv6. This comprehensive security suite includes ND inspection, RA guard, DHCPv6 guard and neighbor binding integrity check,providing unparalleled protection against a vast range of address spoofing and man in the middle attack on IPv6 networks.◦DOS (denial-of-service) attack prevention maximizes network uptime in the presence of an attack. ◦Protection of management sessions using Radius, TACACS+ and local database authentication as well as secure management sessions over SSL, SSH, and SNMPv3.●Power over Ethernet: Cisco 300 Series Switches are available with up to 48 PoE ports of FastEthernet or Gigabit Ethernet connectivity. This capability simplifies advanced technology deployments such as IP telephony, wireless, and IP surveillance by allowing you to connect and power network endpoints over a single Ethernet cable. With no need to install separate power supplies for IP phones or wireless access points, you can take advantage of advanced communications technologies more quickly, and at a lower cost. Some models support both IEEE 802.3af PoE and IEEE 802.3at PoE+ while others support IEEE 802.3af PoE only.●IP telephony support: Cisco 300 Series Switches include embedded QoS intelligence to prioritizedelay-sensitive services such as voice and video, simplify unified communications deployments, and help ensure consistent network performance for all services. For example, automated voice VLAN capabilities let you plug any IP phone (including third-party phones) into your IP telephony network and receive an immediate dial tone. The switch automatically configures the device with the right VLAN and QoS parameters to prioritize voice traffic.●Networkwide Automatic Voice Deployment: Using a combination of CDP, LLDP-MED, AutoSmartports, and VSDP (Voice Services Discovery Protocol – a unique patent-pending Cisco protocol), customers can deploy an end-to-end voice network dynamically. The switches in the networkautomatically converge around a single voice VLAN and QoS parameters and then propagate them out to the phones on the ports where they are discovered. For example, automated voice VLAN capabilities let you plug any IP phone (including third-party phones) into your IP telephony network and receive an immediate dial tone. The switch automatically configures the device with the right VLAN and QoS parameters to prioritize voice traffic.●Advanced network management capabilities: As managed switches, the Cisco 300 Series lets youuse a variety of advanced features to control traffic over your network. Features include:◦Static routing/Layer 3 switching between VLANs: This capability allows you to segment your network into separate workgroups and communicate across VLANs without degrading applicationperformance. As a result, you can manage internal routing with your switches and dedicate your router to external traffic and security, helping your network run more efficiently.◦IPv6 support: As the IP network addressing scheme evolves to accommodate more devices, you can make sure that your network is ready. The Cisco 300 Series provides native support for IPv6, the newest version of the Internet Protocol, as well as the previous IPv4 standard. As a result, you will be able to move up to the next generation of networking applications and operating systems without an extensive equipment upgrade.◦Dual image support: With the ability to maintain dual images of your switches, you can perform software upgrades without having to take the network offline and without worrying about an outage during an upgrade.◦Dual Configuration files support: Allows configuring the device, validating that it is configured correctly and then saving this configuration to become effective after reboot. Additionally, a mirror configuration file, providing automatic back-up of the latest stable configuration file maximizesnetwork uptime.◦Remote management: Using Simple Network Management Protocol (SNMP), you can set up and manage all switches and other Cisco devices in your network remotely, instead of having to directly connect to them.◦Additional management options: The switches can be fully managed using the Web GUI or using a full command-line interface (CLI).●Optimal energy efficiency: Cisco 300 Series Switches are designed with a variety of power-savingfeatures across all models, providing the industry’s broadest portfolio of “green” s witches. These switches optimize power use to protect the environment and reduce energy costs, withoutcompromising performance. Power-saving features include:◦The latest application-specific integrated circuits (ASICs), using low-power 65-nanometer technology (these chipsets allow for lower power consumption and thinner, more efficient designs).◦Support for the Energy Efficient Ethernet (IEEE 802.3az) standard, which reduces energy consumption by monitoring the amount of traffic on an active link and putting the link into a sleep state during quiet periods.◦Automatic power shutoff on ports when a link is down.◦Embedded intelligence to adjust signal strength based on cable length.◦Fanless design in most models, which reduces power consumption, increases reliability, and provides quieter operation.◦LEDs can be turned off to conserve power.●Expansion ports: The Cisco 300 Series provides more ports per Gigabit Ethernet switch thantraditional switch models, giving you more flexibility to connect and empower your business. Gigabit Ethernet models feature 28- and 52-port switches, versus traditional devices that offer 20 or 44 ports with four shared ports giving you more value. The Cisco 300 Series also offers mini gigabit interface converter (mini-GBIC) expansion slots that give you the option to add fiber-optic or Gigabit Ethernet uplink connectivity to the switch. With the ability to increase the connectivity range of the switches, you have more flexibility to design your network around your unique business environment, and to easily connect switches on different floors or across the business.●Multiple languages: The Cisco 300 Series is available in seven languages: English, French, German,Italian, Spanish, Japanese, and simplified Chinese.

CISCO数据设置参考

CISCO路由器在ISDN与数据网间互连中的应用摘要：ISDN与数据网的互连是广州市商业通信网工程的一项重要工作，本文对路由器在两网互连中的桥梁作用做了一些介绍，重点在路由器参数配置和调试方面提出参考性意见。

关键词：ISDN 远程接入IP IOS随着Internet、Intranet、远程个人办公室的浪潮兴起，ISDN做为一种廉价、中高速的接入手段日益受到人们欢迎，各种含ISDN远程接入的网络产品纷纷涌现，针对市场的需求，国内一些电信部门推出了ISDN接入Internet、Intranet的业务。

目前，CISCO路由器在中国的数据网中扮演了重要的角色，本文将谈谈CISCO路由器在ISDN数据网间的互连中的应用。

一、CISCO路由器的ISDN功能及参数设置从网络结构看，可以划分为ISDN业务提供方和ISDN远程接入方，前者如电信部门、一些ISP等，后者多为用户。

图图1 ISDN业务提供方和ISDN远程接入方在业务提供者一侧，常用的带ISDN功能的CISCO路由器有7000系列、4500系列、3600系列；在远程接入方，常用的CISCO、ISDN路由器有2500系列中ISDN产品、1000系列中ISDN产品、760系列中ISDN产品，这几种产品均带有BRI端口，可提供2B＋D共128K的接入速率，用户甚至可以采用CISCO200系列的PC内置ISDN适配卡，俞地犹如Modem一样拨号上网，只是传输网是基于ISDN而不传统的PSTN，本文将以4500、1000为例，介绍相应的参数配置，同时也对CISCO200系列作些介绍，至于760系列，虽然这是一种典型的远程ISDN接入设备，但不带CISCO的IOS软件，本文不作讨论。

1、按静态IP用户配置设想有如下一个网络，见图二。

图图二按静态IP用户配置的网络范例在这个例子中，用户申请到一个子网202.100.100.0/27，这是从C类网202.100.100.0/24划分出的一个子网，用户以CISCO1003路由器做为网关设备，经ISDN网与4500相连。
