一、DHCP开局
(一)创建DHCP池
Switch_config#ip dhcpd enable//开启设备的dhcp服务Switch_config#ip dhcpd pool vlan20//创建dhcp池并取名为vlan20
Switch_config_dhcp#network 192.168.20.0 255.255.255.0//配置地址池的网络地址
Switch_config_dhcp#default-router 192.168.20.1//该网段的网关Switch_config_dhcp#range 192.168.20.2 192.168.20.254//需要分配的地址范围
Switch_config_dhcp#dns-server 114.114.114.114//配置DNS服务器
可选配置:
1、需要把某个固定的IP地址分配给某个主机
Switch_config_dhcp#ip-bind X.X.X.X hardware-address ?
WORD-- line -hexadecimal string (aa-bb-cc-dd...)
2、配置dhcp的租约时间(时间配置为天/小时/分钟)
Switch_config_dhcp#lease 0 12 0//配置租约时间为12个小时
<0-365>--租用天数
infinite--租期不限
注:
(1)range范围为10个C类地址段,一个DHCP池配置range只能8。

(2)配置了ip-bind后无租约时间限制,会一直存在在绑定表中。

(二)配置dhcp中继
Switch_config#int vlan 20
Switch_config_v20#ip helper-address X.X.X.X//在网关地址上配置
(三)查看DHCP服务器
1、查看设备DHCP分配的地址情况
Switch#show ip dhcpd binding
(状态)(释放时间)
IP Address Hardware Address Type Lease Expired
192.168.10.211-22-33-44-55-66manual(静态)infinite
192.168.20.3e8-03-9a-35-2b-ed automatic(动态)THU JAN 01 17:29:08 1970
2、查看设备DHCP池的状态
Switch_config#show ip dhcpd pool
Pool vlan20 :
Network : 192.168.20.0 255.255.255.0
Range : 192.168.20.2 - 192.168.20.254
192.168.20.2binding hdaddress11-22-33-44-55-66//静态IP地址绑定
Total address : 253//能分配的总地址数Leased address : 2//租用地址Abandoned address : 0//废弃地址
Pended address : 0//手写地址
Available address : 251//可分配地址
二、DHCP-snooping开局
(一)配置dhcp-snooping功能
在LSW1和LSW2上配置
Switch_config#ip dhcp-relay snooping//全局下开启dhcp-snooping功能(所有vlan),如果只需要某个vlan启用该功能,则在这条命令的后面加上vlan即可
Switch_config#int g0/1
Switch_config_g0/5#dhcp snooping trust //把上联接口设置为信任接口
(二)DAI功能配置
功能介绍:在属于某个VLAN的所有物理端口进行ARP动态监测,如果该接口收到的ARP报文的源MAC和源IP地址不满足接口上配置的MAC和IP地址绑定关系,则拒绝处理该报文。

接口上配置的绑定关系可以是DHCP动态绑定的,也可以是手工配置的。

如果物理接口上没有配置任何MAC和IP地址绑定,则交换机拒绝转发所有ARP报文。

在LSW1和LSW2上配置
Switch_config#ip arp inspection vlan //启用某个vlan的DAI功能WORD-- VLAN IDs(1-4094), such as (1,3,5,7) Or (1,3-5,7) Or (1-7)
Switch_config#int g0/1
Switch_config_g0/5#arp inspection trust//设置上联接口为信任端口
(三)IP源地址检测功能配置
功能介绍:启动IP源地址监测的VLAN,属于该VLAN的所有物理端口收到的IP 报文的源MAC和源IP地址不满足接口上配置的MAC和IP地址绑定关系,则该报文被拒绝处理。

接口上配置的绑定关系可以是DHCP动态绑定的,也可以是手工配置的。

如果此物理接口上没有配置任何MAC和IP地址绑定,则交换机拒绝转发所有该接口收到的IP报文。

在LSW1和LSW2上配置
Switch_config#ip verify source vlan //启用某个vlan的IP源地址检测功能
WORD-- VLAN IDs(1-4094), such as (1,3,5,7) Or (1,3-5,7) Or (1-7)
Switch_config#int g0/1
Switch_config_g0/5#ip-source trust//设置上联接口为信任端口
注:启用DAI和IP源地址检测功能必须先开启DHCP-snooping功能,DAI和IP源地址检测功能一般属于接入层技术,在接入交换机上配置即可
(四)维护DHCP-snooping
(1)Switch_config#show ip dhcp-relay snooping
ip dhcp-relay snooping//启用DHCP-snooping的vlan
ip arp inspection vlan1-4094//启用DAI的vlan
ip verify source vlan1-4094//启用IP源地址检测的vlan

三、MSTP开局
根据现场客户要求达到冗余备份,流量负载均衡的情况
(一)配置MSTP
LSW1和LSW2配置:
Switch_config#spanning-tree mode mstp//配置生成树模式Switch_config#spanning-tree mstp name 123 //配置MSTP的域名Switch_config#spanning-tree mstp revision 1//配置MSTP修订号Switch_config#spanning-tree mstp instance 1 vlan 10//配置MSTP实例
可用配置:
Switch_config(D)#spanning-tree mstp hello-time//配置设备的hello时间
<1-10>-- Number of seconds between generation of config BPDUs
Switch_config(D)#spanning-tree mstp max-age//配置设备的最大老化时间
<6-40>-- Maximum number of seconds the information in a BPDU is valid Switch_config(D)#spanning-tree mstp max-hops//配置MSTP的最大跳数
<6-40>-- Maximum number of hops a BPDU is valid
Switch_config(D)#spanning-tree mstp forward-time//配置MSTP的转发时延

五、ACL
(一)ACL配置
(1)配置标准ACL(只匹配数据包中的源地址)
Switch_config#ip access-list standard 123//创建标准ACL并取名为123
Switch_config_std#permit 192.168.1.1 255.255.255.0//允许192.168.1.0网段
Switch_config_std#deny 192.168.2.0 255.255.255.0//拒绝192.168.2.0网段
Switch_config#int g0/1
Switch_config_g0/1#ip access-group 123 //把ACL应用在接口上(默认在in方向)egress--配置在出口
<cr>--配置在入口
或:
Switch_config#ip access-group 123 vlan 1 //应用在某个vlan 上
egress-- Configured on egress
<cr>-- Configured on ingress
(2)配置扩展ACL(匹配数据包的源目IP、源目端口号、协议等)Switch_config#ip access-list extended 456//创建扩展ACL并取名为456
拒绝192.168.1.0网段访问192.168.2.0网段:
Switch_config_ext#deny ip 192.168.1.0 255.255.255.0 192.168.2.0 255.255.255.0
(二)查看ACL配置

--------------------------------------------------------------------
1deny ip 192.168.1.0 255.255.255.0 192.168.2.0 255.255.255.0
六、端口聚合
增加链路带宽,使链路达到冗余的效果
(一)端口聚合配置
LSW1和LSW2配置:
Switch_config#int port-aggregator 1//创建端口聚合组1
Switch_config_p1#switchport mode trunk//设置端口聚合组为trunk接口
Switch_config#int range g0/46-48//批量配置接口
Switch_config_if_range#switchport mode trunk//设置物理接口模式为trunk接口
Switch_config_if_range#aggregator-group 1 mode//配置聚合组的模式(静态和动态)
static -- Static port aggregate to aggregator
lacp-- Enable lacp protocol negotiate
注意事项:
配置端口聚合时,注意保持交换机上端口下的配置一致。

不然会出现聚合失败的情况,所以建议配置完聚合之后再对聚合端口进行配置。

例:
interface Port-aggregator1
switchport mode trunk
配置完成之后,注意检查。

show aggregator-group 1 brief 检查聚合组下端口是否都为(UA)状态,拔掉其中一条线路看看业务是否还是通讯。

若可以,则拔掉另外一条线路测试。

(二)查看端口聚合组
(1)查看端口聚合组简要信息
Switch#show aggregator-group 1 brief

Flags: D - down A - Use In port-aggregator
U - Up I - Not In port-aggregator

g0/48(UA)g0/46(DI)g0/47(UA)
注:UA表示该端口在端口聚合组中,端口也是up的;DI表示该端口是down的也不在端口聚合组中
(2)查看端口聚合组每个端口的流量统计
Switch#show int port-aggregator 1

2、显示RNP信息
Switch#show bvss rnp
RNP is running. CfgPri 255, SwitchType 0x107b, Slot 0
System started, ignoreTimeoutCnt 0
DomainId 1, MemberId 1, LoopTopology 0, Merge 0, Master State MasterMemId 1, BackupMemId 2, MasterGlbMacAddr 00e0.0f62.0035 OldMasterMemberId 0, OldMasterWhile 0, txAdvPduCnt 3353
bvss link group 1 is usable, bvss link group 2 is not usable.
Pri info for member 1 (SwitchType 107b, slot 0):
Priority 255, RunningTime 17097, MAC 00e0.0f62.0035
//成员1优先级,运行时间,MAC地址
Pri info for member 2 (SwitchType 107b, slot 0):
Priority 254, RunningTime 4198, MAC fcfa.f736.c300
(三)堆叠环境下常用配置
1、MAC地址同步命令
Switch_config#mac address-table rpc [trunk][all]
注:若有跨板卡的聚合,建议配置;若没有跨板卡聚合,则无需配置;
2、关闭stp引起的刷新mac地址表
Switch_config#no spanning-tree fast-aging flush-fdb
3、arp重传
Switch_config#arp retry-allarp
十、radius认证
(一)radius配置
LSW1配置
Switch_config#dot1x enable //全局下开启dot1x认证Switch_config#int g0/2
Switch_config_g0/2#dot1x authentication type eap//端口认证类型Switch_config_g0/2#dot1x authentication method ?//端口认证方式WORD-- AAA authentication method name
Switch_config_g0/2#dot1x port-control auto//端口启用802.1X认证Switch_config#radius-server host X.X.X.X//配置radius服务器Switch_config#radius-server key 0 XXX//配置radius密钥Switch_config#aaa authentication dot1x XXX group radius//配置radius3A认证
(二)guest vlan
guest-vlan功能:在客户端没有响应时,给予相应端口有限的访问权限(例如下载客户端软件)。

guest-vlan可以是系统中任何一个已配置的vlan。

Switch_config#dot1x guest-vlan//开启guest vlan功能Switch_config_g0/2# dot1x guest-vlan X//接口下配置guest vlan
(三)查看dot1x
Switch#show dot1x
802.1X Parameters
reAuthen No//是否开启了重认证
reAuth-Period3600//重认证周期
quiet-Period60//认证失败后重认证等待时间Tx-Period30//报文发送频率
Supp-timeout30
Server-timeout30
reAuth-max5//重认证次数
max-request3//最大发送请求次数
authen-type Eap//认证类型
十一、RIP
(一)配置
LSW1的配置
Switch_config#router rip 1//配置rip进程号
Switch_config_rip_1#version 2//配置rip版本
Switch_config_rip_1#exi
Switch_config#int vlan 1
Switch_config_v1#ip rip 1 enable//接口启用rip(相当于华为的network)
Switch_config#int vlan 2
Switch_config_v2#ip rip 1 enable
Switch_config#int vlan 3
Switch_config_v3#ip rip 1 enable
Switch_config#int vlan 4
Switch_config_v4#ip rip 1 enable
LSW2的配置
Switch_config#router rip 1//配置rip进程号
Switch_config_rip_1#version 2//配置rip版本
Switch_config_rip_1#exi
Switch_config#int vlan 1 0
Switch_config_v10#ip rip 1 enable//接口启用rip(相当于华为的network)
Switch_config#int vlan 20
Switch_config_v20#ip rip 1 enable
Switch_config#int vlan 30
Switch_config_v30#ip rip 1 enable
Switch_config#int vlan 40
Switch_config_v40#ip rip 1 enable
(二)查看rip
(1)显示rip实例当前状态
Switch#show ip rip
Process: 1 //进程号
Update: 30,Expire: 180,Holddown: 120//路由更新时间、宣告无效时间、删除路由时间
Input-queue: 200
Validate-update-source: Enable
zero-domain-check: Enable
Neighbor List://邻居
interface List://启用的接口interface VLAN1
(2)查看某个rip实例的所有路由
Switch#show ip rip 1 database
192.168.1.0/24directly connected VLAN1//直连路由。
