OVERVIEW
This product bulletin contains content and delivery information for Cisco IOS Software Release 12.2(25)SEB. For more information about the
Cisco IOS Software release process, refer to Product Bulletin 537.
The following new Cisco IOS Software features are available as a free software upgrade to current users of Cisco Catalyst 3750, Catalyst 3560,
Catalyst 3550, and Catalyst 2970 series switches:
Dynamic ARP inspection (DAI) and IP Source Guard (IPSG) support added to the IP Base image for the Cisco Catalyst 3750, Catalyst 3560,
and Catalyst 3550 series. DAI and IPSG use a higher level of network security by preventing breaches such as "man-in-the-middle" attacks.
Private VLAN support added to the IP Base image for the Cisco Catalyst 3750 and Catalyst 3560.
Port security for voice VLANs support facilitates the configuration of voice VLANs for access ports such that an IP phone can not be moved
within a switch unless the switch is reconfigured. Only one identified, secure PC is allowed per IP phone, and the PC can bypass the IP phone
if desired.
Internet Group Management Protocol (IGMP) Leave Timer Change support.
Reformation software packaging support allows consistent image naming across the Cisco Catalyst switching portfolio. Cisco IOS Software
Release 12.2(25)SEB will support IP Advanced Services, IP Services, IP Base, and LAN Base images. Images formally known as AIS, EMI,
SMI, and EI will now map to IP Advanced Services, IP Services, IP Base, and LAN Base, respectively.
