Cisco Cisco IOS Software Release 12.2(55)SE

For additional recovery procedures, see the “Troubleshooting” chapter in the software configuration 
guide for this release.

You can assign IP information to your switch by using these methods:

The CLI-based setup program, as described in the hardware installation guide.

The DHCP-based autoconfiguration, as described in the software configuration guide.

Manually assigning an IP address, as described in the software configuration guide.

Auto-QoS enhancements that add automatic configuration classification of traffic flow from video 
devices, such as the Cisco Telepresence System and Cisco Surveillance Camera.

Support for CDP and LLDP enhancements for exchanging location information with video end 
points for dynamic location-based content distribution from servers.

Support for dynamic creation or attachment of an auth-default ACL on a port that has no configured 
static ACLs configured.

Support for VLAN assignment on a port configured for multi-auth mode. The RADIUS server 
assigns a VLAN to the first host to authenticate on the port, and subsequent hosts use the same 
VLAN. Voice VLAN assignment is supported for one IP phone. 

Memory consistency check routines to detect and correct invalid ternary content addressable 
memory (TCAM) table entries.

Support for the Security Group Tag (SCT) Exchange Protocol (SXP) component of Cisco TrustSec, 
a security architecture using authentication, encryption, and access control.

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 
syslog messages.

Support for Embedded Event Manager (EEM) for device and system management to monitor key 
system events and then act on them.

Support for QoS class-default policy placement.

Support for OSPF for routed access to enable customers to extend Layer 3 routing capabilities to the 
access or wiring closet. This feature does not support multiple OSPFv2 and OSPFv3 instances 
without route restrictions. 

MAC move to allow hosts (including the hosts connected to an IP phone) to move across ports within 
the same switch without any restrictions to enable mobility. With MAC move, the switch treats the 
reappearance of the same MAC address on another port as a completely new MAC address.

MAC replace can be configured so that when a host disconnects from a port without ending its 
session, the session can be ended and the authentication sequence reset when a new MAC address 
connects to the port.
