On the Cisco Catalyst 2960 and 2960-S series, it adds support for 16 static IPv4 routes in the LAN Base image, and adds support for Link Layer Discovery Protocol Media Endpoint Discovery (LLDP-MED) and Dynamic Host Configuration Protocol (DHCP) Snooping in the LAN Lite image. This release also introduces a number of enhancements, including extensions to the Cisco Smart Install technology; improvements to the Cisco EnergyWise and Auto SmartPorts technologies; and enhancements to identity-based networking, manageability, and security.This product bulletin contains content and delivery information for Cisco IOS Software Release 12.2(55)SE.New FeaturesThe following new features and enhancements for enterprise switches are available with this Cisco IOS Software release:●Ease of use and manageability enhancements: This release incorporates important manageabilityimprovements to Cisco Catalyst Smart Operations such as Auto SmartPorts “phase 3” enhancements and Smart Install enhancements, which are meant to reduce time of deployment and deployment costs inheterogeneous switch, router, and endpoint device environments. In particular, Auto SmartPortsenhancements include support for new and improve macros and enhancements specific for wireless access points. Smart Install enhancements include support of new devices as client and directors, support ofconfiguration file backup and the ability to easily replace (“zero touch”) a switch in the network. A zero touch replacement process makes sure the latest image and configuration is downloaded during the devicereplacement process. These enhancements are also discussed in the “Ease-of-Use and ManageabilityEnhancements” section of this document.●Cisco Medianet enhancements: Auto-QoS’s automatic configuration has been extended to include theclassification of data, voice, and video flows, including those from video endpoints such as the CiscoTelePresence™ System and Cisco Surveillance Camera. In addition, a switch port can now send locationinformation using LLDP and Cisco Discovery Protocol to the endpoint to which it is connected for dynamic location-based content distribution from servers. Cisco Discovery Protocol now supports a location type-length value (TLV) as well as an application ID TLV and a location server TLV for the aforementionedpurpose.●Cisco TrustSec™ 4.1 Identity enhancements: This release enhances Cisco Identity-Based NetworkingServices (IBNS) with advanced features and extensions geared to improve integration, scalability, andmobility. The enhancements include authentication, authorization, and accounting (AAA) guarantee-firstsupport, MAC replace, support for VLAN assignment on a port configured for multiauth mode, a configurable option to turn off 802.1X and MAC Authentication Bypass (MAB) informational messages, port access control list (ACL) improvements, and a new Address Resolution Protocol (ARP) tracking probe configuration option.These enhancements are discussed in more detail in the “Identity Enhancements” section of this document.●Cisco EnergyWise enhancements: This release supports an enhanced CISCO-ENERGYWISE-MIBimplementation that adds 17 new MIB objects in the cewNeighborTable, including various EnergyWiseendpoint (child) attributes such as device MAC addresses.Figure 1 shows EnergyWise ecosystem and MIB usage.Figure 1. EnergyWise Ecosystem and MIB usage●OSPF for Routed Access: Starting from Cisco IOS Release 12.2(55)SE, the IP Base image supports a newfeature called OSPF for Routed Access. OSPF for Routed Access is designed specifically to enable you to extend Layer 3 routing capabilities to the wiring closet. It supports only one OSPFv2 and one OSPFv3instance, with a maximum number of 200 dynamically learned routes.With the typical topology (hub and spoke) in a campus environment, where the wiring closets (spokes) are connected to the distribution switch (hub) forwarding all nonlocal traffic to the distribution layer, the wiring closet switch need not hold a complete routing table. A best practice design, where the distribution switch sends a default route to the wiring closet switch to reach interarea and external routes (OSPF stub or totally stub area configuration), should be followed when OSPF for Routed Access is used in the wiring closet. For more details, visit /en/US/partner/docs/solutions/Enterprise/Campus/routed-ex.html.Note that the IP Base image entitles the user to configure OSPF for Routed Access; however, the restrictions on the number of routes and instances are not enforced in this release.The IP Services image is required if one needs multiple OSPFv2 and OSPFv3 instances without routerestrictions. Additionally, the IP Services image is required to enable the multi-VRF-CE feature.●Support for EEM in IP Base: Support for the powerful EEM feature set, previously available only in the IPServices image, is now available in IP Base as well.Table 1 shows OSPF for Routed Access and EEM additions to the IP Base image.

IP Base feature set includes all LAN Base features.●Support for 16 static IPv4 routes in LAN Base (2960, 2975, and 2960-S only): With the new LAN BaseRouting SDM template, support is added for up to 16 user-configurable static IPv4 routes, in addition todirectly connected routes and any default routes for the management interface. Static routing is supported only on SVIs. Router access control lists (RACLs) can be configured in conjunction with static routing as well.●LLDP-MED support in LAN Lite (2960 and 2960-S only): Support for the LLDP-MED protocol, previouslyavailable only in the LAN Base feature set (or better), is now available in LAN Lite as well.●DHCP Snooping (including option 82) support in LAN Lite (2960 and 2960-S only): Support for theDHCP Snooping feature, previously available only in the LAN Base feature set (or better), is now available in LAN Lite as well.●Ternary content-addressable memory (TCAM) consistency check routines: Support for new routines todetect and correct invalid TCAM table entries on the Cisco Catalyst 2975, 2960 (not supported on 2960-S), 3560, 3560v2, 3750, 3750v2, and CBS 30x0 switches.●Location enhancements: Support was added in LLDP and Cisco Discovery Protocol to transporthierarchical civic location information. Furthermore, the location information can be transmitted over Cisco Discovery Protocol between wired switches and attached devices, from a switch to the endpoint (when the location info is configured on the switch), or vice versa from the device to the switch (which will store the info and eventually relay it to a location appliance) when the end device’s location is configured by the user.●Improvements in QoS policing rates on the Cisco Catalyst 2960(S) and 2975 in LAN Base: minimumpolicing rate values were lowered from 1 Mbps to 8 Kbps on the Cisco Catalyst 2960 and 2975 and to 16Kbps on the Cisco Catalyst 2960S. The Cisco Catalyst 2960S’s minimum rate granularity is 16 Kbps.●Support for the QoS class-default policy statement on the Cisco Catalyst 2960, 2975, 3560(v2), 3750(v2),3560E/3750E, 3560X/3750X, CBS 31x0, and 30x0 switches (not supported on 2960-S).●Support for a command to increase the NVRAM buffer size up to 1 MB in the rare cases in which a largeconfiguration cannot be saved with the default NVRAM size (512 KB).●Support for the Security Group Tag (SGT) Exchange Protocol (SXP) component of Cisco TrustSec, a securityarchitecture using authentication, encryption, and access control on the Cisco Catalyst 3560E, 3750E,3560v2, 3750v2, 3560, 3750, CBS 31x0, and 30x0 switches. (Cisco Catalyst 3560X and 3750X support SXP since Cisco IOS Software Release 12.2(53)SE.)Cisco Smart Operations Ease-of-Use and Manageability EnhancementsThe following ease-of-use and manageability enhancements are included in this release:●Smart Install enhancements: Smart Install enables plug-and-play configuration and image distribution froma single point of management (director) in the network and therefore can reduce total cost of ownership(TCO) and operational expenses for the customer.In this release support was added for the following platforms:◦Cisco Catalyst 3560X (client or director)◦Cisco Catalyst 3750X (client or director)◦Cisco Catalyst 2960S (client)Moreover, support for CISCO-SMART-INSTALL-MIB was introduced too.Cisco Smart Install is a transparent plug-and-play technology to configure the Cisco IOS Software imageand switch configuration without user intervention. Smart Install utilizes dynamic IP address allocation and the assistance of other switches to facilitate installation, providing transparent network plug and play. Inconjunction with it, Cisco Smart Configuration provides a single point of management for a group ofswitches and adds the ability to archive and back up configuration files to a file server or switch, allowingtransparent zero-touch switch replacement. Zero-touch replacement enables the user to remove a faultyswitch and replace it with a new switch of the same model. When the new switch is detected, the currentconfiguration and Cisco IOS Software are downloaded, allowing switch replacement by a user withoutswitch knowledge.●Auto SmartPorts (ASP) enhancements. The new Auto SmartPorts capabilities include:◦Global configuration macros, to enable the user to apply configuration globally on a switch or on all interfaces of the switch.◦ A last resort macro, to apply a built-in macro on interfaces where a device is detected but is not part of the well-known device list. This capability is useful for the auto configuration of ports connected, for example, to personal computers.◦ A custom macro, to allow the user to set interfaces into a desired “default” configuration state every time ASP removes previously applied macro configuration.◦Per port and global trigger control, which allows greater control over which devices and interfaces are automatically configured using Auto Smart Ports. The user can now select a device’s interface on which a macro needs to be applied and/or select the mode of device detection (for example, Cisco DiscoveryProtocol, LLDP, or MAC-address based).◦Support of use of VLAN IDs as VLAN name parameters.◦Support of the use by wireless access points of the new Cisco Discovery Protocol Auto-QoS extensions, to communicate to the switch the proper bandwidth information in order to apply the corresponding QoSconfiguration on the switch interface.Identity EnhancementsThe following identity enhancements are included in this release:●MAC replace: MAC replace allows new hosts to connect to abandoned ports behind a hub or third-party IPphone without generating a violation. The switch terminates the initial session and resets the authentication sequence based on the new MAC address. For directly connected hosts or for hosts behind Cisco IP phones, the switches now know the initial host has been removed.●AAA guarantee-first support for enabling or disabling system accounting as the first record.●An option to suppress verbose 802.1X, authentication manager, and MAC authentication bypass syslogmessages.●Support for dynamic creation or attachment of an auth-default ACL on a port that has no static ACLconfigured.●Support for VLAN assignment on a port configured for multiauth mode: the RADIUS server assigns aVLAN to the first authenticated host on the port, and subsequent hosts will use the same VLAN. Voice VLAN assignment is supported for one IP phone.●ARP tracking probe enhancement to specify a source IP address for a VLAN.Product Support for New Features and EnhancementsTable 2 summarizes product support for new features of Cisco IOS Software Release 12.2(55)SE for the Cisco Catalyst 3750-X, 3750-E, 3560-X, and 3560-E Series Switches.Table 2.

Downloads of IP Base and IP Services files are monitored for adherence to this requirement. The Cisco Catalyst 3750-X, 3560-X, 3750-E, and 3560-E Series Switches support the new Cisco IOS Software licensing infrastructure, which authorizes and enables the use of the existing Cisco IOS Software feature sets. A special file contained in the switch’s flash memory, called a license file, is examined by Cisco IOS Software when the switch is powered on. On the basis of the license type, Cisco IOS Software enables the appropriate Cisco IOS Software feature set (for more information on packaging and licensing, refer to/en/US/prod/collateral/switches/ps5718/ps6406/white_paper_c11-579326_ps10745_Products_White_Paper.html).Note that the Advanced IP Services license has reached end-of-life status since Cisco IOS Software Release12.2(50)SE.Because of export restrictions on strong cryptography software, a separate image is required for the cryptographic features (Secure Shell [SSH] Protocol, Simple Network Management Protocol Version 3 [SNMPv3], and Kerberos Protocol). These software images can be downloaded from the corresponding Triple Data Encryption Standard(3DES) area of the links provided in this section.。
