Cisco

announces Cisco IOS

Software updates for Cisco Catalyst

3750 Metro, Cisco

ME 3400 and ME 2400 Series Ethernet Access Switches. This release furthers Cisco

leadership by providing integrated services for high availability, multicast, and

manageability for Metro Ethernet deployments.

This product bulletin contains content and delivery information for Cisco IOS Software Release

12.2(40)SE.

The following new features are available with Cisco IOS software release 12.2(40)SE for Metro

Ethernet switches:

●

Resilient Ethernet Protocol (REP): REP is a Cisco technology that allows fast convergence

and high availability in a switch ring topology. The capability provides loop prevention and

does not utilize spanning tree.

●

IP SLAs for Metro Ethernet: Metro Ethernet based SLAs are important for customers. IP

SLAs for Metro Ethernet utilize IEEE 802.1ag Ethernet Operation, Administration, and

Maintenance (OAM) capabilities to automatically validate end-to-end connectivity, jitter, and

latency in a Metro Ethernet network.

●

IP SLAs Label Switch Path (LSP) Health Monitor: The ability to analyze an LSP is useful in

a Multiprotocol Label Switched (MPLS) network. IP SLAs LSP Health Monitor automates

the testing of LSPs in a Layer 3 MPLS VPN network by utilizing MPLS OAM capabilities

within Cisco IOS Software. Each LSP is tested periodically and automatically to determine if

connectivity exists between provider edge devices.

●

MPLS OAM RFC 4379: This feature includes support for LSP ping RFC version (RFC4379)

and MPLS OAM tree trace, which allows the tracing of LSPs across an MPLS network.

●

IP Service-Level Agreements (IP SLAs) Support: Cisco IOS IP SLAs help enable customers

to assure new business-critical IP applications, as well as IP services that utilize data,

voice, and video. With Cisco IOS IP SLAs, users can verify service guarantees, increase

network reliability by validating network performance, proactively identify network issues,

and increase return on investment (ROI) by easing the deployment of new IP services.

Cisco IOS IP SLAs use active monitoring to generate traffic in a continuous, reliable, and

predictable manner, thus facilitating the measurement of network performance and health.

●

IP SLAs Enhanced Object Tracking: IP SLAs Enhanced Object Tracking support will allow

switches utilizing HSRP to track IP SLA measurements and trigger hot standby failover

based upon jitter, packet loss, or latency.
