Release Notes for Cisco Catalyst Blade Switch 3120 for HP, Cisco IOS Release 12.2(55)SE and Later

OL-22860-04

Minimum Cisco IOS Release for Major Features

• The IP Base image supports OSPF for routed access to enable customers to extend Layer 3 routing

capabilities to the access or wiring closet. The IP services image is required if you need 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.

• Support for increasing the NVRAM buffer size for saving large configuration files.

• ARP tracking probe enhancement to specify a source IP address for a VLAN.

• Network Edge Access Topology (NEAT) controls the supplicant port during the supplicant

authentication period. When you connect a supplicant switch to the authenticator switch, the

authenticator port could be error-disabled when receiving Spanning Tree Protocol (STP) bridge

protocol data unit (BPDU) packets and the supplicant switch is not authenticated. The NEAT feature

is now enhanced to block the supplicant port during authentication, to ensure authentication

completes.

Use the dot1x supplicant controlled transient global configuration command to control access to

the supplicant port during authentication. Use the no form of this command to provide access to the

supplicant port during the authentication period.
