Introducing Cisco IOS Software Release 12.2(46)SE for Catalyst 3750-E, 3750, 3560-E, 3560, 2960 Series switches, and Catalyst Blade Switch Series

This release furthers Cisco leadership by providing integrated services for Layer 2 and Layer 3 networks, IPv6, and manageability for enterprise deployments. The following are the new features available:

• HSRP Version 2: HSRP sub-second timers provides improved high availability and faster convergence in case of network failure. The new enhancements include millisecond timer values and a larger range of group numbers.

• Enhanced Port Aggregation Protocol (PAgP): PAgP has been enhanced to support the Virtual Switching System (VSS) over EtherChannel®.

• Disable per VLAN MAC Learning: MAC address learning can be disabled on a per VLAN bases.

• Autostate Exclude: Autostate exclude mode is now supported.

• Dynamic Host Configuration Protocol (DHCP) for IPv6: DHCP client, server and relay for IPv6 addresses are now available.

• HSRP for IPv6: HSRP is used by customers to provide high availability and allow fast convergence during a network outage. HSRP now supports IPv6 networks.

• IPv6 QOS Trust: IPV6 packets with QOS marking are now trusted on a per port basis. This feature is only available on the 3750E and 3560E product lines.

• Enhanced Object Tracking (EOT) Static Route Support: Reliable static routing EOT allows users to track static routes using parameters based upon connectivity, latency, packet loss, and jitter and force a failover to utilize a backup route under adverse network conditions. Per VRF EOT static route support is also available.

• DHCP Port-Based Allocation: The Cisco IOS Software DHCP server can now allocate the same address to a specific port. This new feature allows persistent allocation of IP addresses to specified network devices.

• Local Web Authentication Banner: Local web authentication banner is an enhancement to allow users to add company banners and customize the webpage.

• Cisco Network Admission Control (NAC) and Identity MIB support:. Now supported to help NAC deployments is the Cisco NAC-NAD-MIB. The Cisco Port Access Entity (PAE) has been enhanced to support new MIB objects.

• Generic Message Authentication for Secure Shell (SSH) Protocol: The SSH Protocol now supports generic message authentication and is compliant with RFC 4256.

• Voice Aware Security Violations: Security violations on a port are now voice aware. If a voice VLAN is present, security violations for data and voice are treated separately, allowing better control of network security when using 802.1x and MAB.

• Multi Domain Authentication (MDA) for Cisco Catalyst 2960: MDA is now supported on the Cisco Catalyst 2960.

• Radius Filter ID Attribute for Cisco Catalyst 2960: Support for radius filter ID is now available on the Cisco Catalyst 2960 and can be used with IEEE 802.1x deployments.

• Software Activation Evaluation License: The Cisco Catalyst 3560-E, 3750-E, and CBS31xx support the software activation feature. Evaluation or built-in software activation allows the customer to enable a temporary license for quick replacement of a failed switch. The temporary license can be used while a return material authorization (RMA) is processed.

• Software License Transfer: The software activation license for the Cisco Catalyst 3560-E, 3750-E, and CBS31xx may now be transferred between switches. If one switch is being removed from the network, the license for that switch may be moved between switches using the Cisco license portal.

• Digital Optical Monitoring (DOM) for the 3560E-12D and 3560E-12SD: DOM is now supported on the new Cisco Catalyst 3560E-12D and 3560E-12SD switches. Included is DOM support for the SX, LX, and ZX modules.
