Cisco announces Cisco IOS® Software updates for Cisco Catalyst® 3750 Metro Series Switches and Cisco® ME 3400 and ME 3400E Series Ethernet Access Switches. This release advances Cisco's leadership role by providing enhanced resiliency, manageability, routing, usability, and scalability features for Metro Ethernet deployments.
This product bulletin contains content and delivery information for Cisco IOS Software Release 12.2(52)SE.
The following new features are available with Cisco IOS Software Release 12.2(52)SE for Metro Ethernet switches:
• IEEE 802.1ag Connectivity Fault Management Version 8.1 (CFMv8.1): Provides standards-compliant implementation of the CFM protocol; functions supported include:
– CFM outward-facing maintenance endpoints (MEPs) on switch port
– CFM over untagged and QinQ frames
– CFM MIB (CFM statistics collection and MIB views of maintenance domain management)
– Backward compatibility with CFMv1.0
• ITU-T Y.1731: Provides support for the ITU-T recommendation for fault management and offers an extension to the IEEE 802.1ag function; the following capabilities are supported:
– Alarm indication signal (AIS)
– Remote defect indication (RDI)
– Ethernet lock signal (LCK)
• Two-Way Active Measurement Protocol (TWAMP) responder: Provides the industry-standard implementation of the IP service-level agreement (SLA)
• IP Version 6 (IPv6): Improves the scalability of IP networks by supporting the growing number of users, applications, and services; functions supported include:
– Access control lists (ACLs)
– Dynamic Host Configuration Protocol (DHCP)
– Neighbor discovery (RFC2461)
– Routing (unicast routing, Routing Information Protocol [RIP], Enhanced Interior Gateway Routing Protocol [EIGRP], External Border Gateway Protocol [eBGP], Open Shortest Path First Version 3 [OSPFv3], and static routes) in the global table
– IPv6 HTTP and HTTPS
– IPv6 host functions
– IPv6 stateless autoconfiguration
– IPv6 default router preference
– IPv6 DHCP relay (global table)
– IPv6 DHCP server (global table)
– IPv6 QoS trust capability
IPv6 is a new feature for the Cisco Catalyst 3750 Metro Series. The Cisco ME 3400 and ME 3400E Series switches already support IPv6, introduced in Cisco IOS Software Release 12.2(50)SE.
• IPv6 multicast: Provides support for functions including:
– Multicast Listener Discovery Version 1 (MLDv1) v1 snooping
– MLDv2 snooping
IPv6 multicast on the Cisco Catalyst 3750 Metro Series is supported on the global routing table only and is not virtual route forwarding (VRF) aware.
• Resilient Ethernet Protocol (REP) link status layer (SLS) age-out timer improvement: Allows fast convergence of carrier Ethernet networks when the Layer 2 link failure is reported with a delay in the network
• Digital optical monitoring (DOM) threshold: Monitors real-time optical parameters on DOM Small Form-Factor Pluggables (SFPs) and compares them to factory-reset values to generate alarm and warning thresholds
• Capability to add up to 2000 multicast VLAN registration (MVR) groups in the configuration file
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 Version 3 [SNMPv3], 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.
