Cisco IOS Software Releases 12.2 Special and Early Deployments

PB493554

Cisco^® announces Cisco IOS^® Software updates for Cisco Catalyst^® 3750-E, 3750,
3560-E, 3560, 2960, and Cisco 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.

• Hot Standby Router Protocol (HSRP) Version 2: HSRP version 2 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^®. The switch will automatically serve as a VSS client, using enhanced PAgP on this EtherChannel for dual-active detection.

• Disable per VLAN MAC Learning: Conservation of switch resources is an important consideration in large-scale networks. The ability to disable the learning of host MAC addresses on a per VLAN basis allows the user to select how hardware resources are utilized within the switch. This capability improves scalability of resources in a Layer 2 network.

• Autostate Exclude: Autostate exclude mode allows you to specify the ports to exclude from Autostate. In normal Autostate mode, the Layer 3 interfaces remain up if at least one port in the VLAN remains up. If you have appliances, such as load balancers or firewall servers that are connected to the ports in the VLAN, you can configure these ports to be excluded from the Autostate to make sure that the forwarding switched virtual interface (SVI) does not go down if these ports become inactive.

• Dynamic Host Configuration Protocol (DHCP) for IPv6: DHCP client, server and relay for IPv6 addresses are now supported. DHCP allows automated configuration and IP address allocation in an IPv6 network.

• 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.

• 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.

• DHCP Port-Based Allocation: DHCP is the standard mechanism to automatically allocate IP addresses. The Cisco IOS Software DHCP server functionality 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: Web authentication is a key security feature that presents an authentication webpage before users are allowed to enter the network. The correct username and password are required for network access. 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: User authentication and security provided by NAC are essential for customer networks. The Cisco NAC security solution offers a systems approach to customers for assuring endpoint device compliancy and vulnerability checks. Now supported to help NAC deployments is the Cisco NAC-NAD-MIB. The Cisco Port Access Entity (PAE) and Cisco-PAE-MIB provide information for IEEE 802.1x deployments and identity access to the network.

• 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.

• Multi Domain Authentication (MDA) for Cisco Catalyst 2960: MDA is an essential feature for voice deployments, allowing the phone and PC to authenticate separately on to the network. MDA is now supported on the Cisco Catalyst 2960 platform.

• 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. DOM supports the SX, LX, and ZX modules.
