Cisco® announces Cisco IOS® Software updates for Cisco Catalyst® 3750 Metro, ME 3400, and ME 2400 Series Switches. This release furthers Cisco leadership by providing Multiprotocol Label Switching (MPLS) Traffic Engineering and Fast Reroute, enhanced routing, resiliency, and manageability features for Metro Ethernet deployments.

This product bulletin contains content and delivery information for Cisco IOS Software Release 12.2(46)SE.
The following new features are available with Cisco IOS Software Release 12.2(46)SE for Metro Ethernet switches:

• MPLS Traffic Engineering (TE) and Fast Reroute (FRR): Allow service providers to increase the network reliability and availability. The feature guarantees fast recovery after a link or node failure in the MPLS network. FRR protects from link and node failures by locally repairing the label switched path (LSP) at the point of failure, rerouting all LSP traffic crossing a failed link over backup tunnels that bypass the failed link or node..

• Dynamic Host Configuration Protocol (DHCP) Port-Based Allocation: Enhances network management by allowing the Cisco IOS Software DHCP server to always offer the same IP address to the device connected to a given switch port. Any new device connecting or old device reconnecting to the port will be allocated the same IP address.

• Resilient Ethernet Protocol (REP) configurable LSL (Link Status Layer) timeout: Allows user to adjust REP's age-out timer and reduce failure detection time in case of loss of signal (LOS).

• REP clear counter enhancement: Allows service providers to optimize the manageability and troubleshooting of REP networks by resetting REP statistics counters when needed.

• Hot Standby Routing Protocol (HSRP) v2: Provides subsecond failover to backup routes and improves manageability and troubleshooting beyond what is possible with HSRP v1.

• Digital Optical Monitoring (DOM) Support for SX and LX Small Form-Factor Pluggables (SFPs).

Table 1 describes product support for new features of Cisco IOS Software Release 12.2(46)SE for Metro Ethernet switches, and Table 2 lists the supported switches.

Because of export restrictions on strong cryptography software, a separate image is required for the cryptographic features (Secure Shell [SSH] Protocol, Simple Network Management Protocol [SNMP] v3, and Kerberos Protocol). These software images can be downloaded from the corresponding Triple Data Encryption Standard (3DES) area of the links provided in this section. Note that the Cisco Advanced IP Services license is available only in cryptographic format.
