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. (Catalyst 3750 and 3560)

•
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.
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.
