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 enterprise

Ethernet switches:

●

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.

●

Source-Specific Multicast (SSM): The SSM capability is an efficient and optimized multicast

protocol that is used for one-to-many multicast applications such as video. The protocol is

easier to deploy than traditional multicast protocols and utilizes Internet Group

Management Protocol version 3 (IGMPv3).

●

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.

●

Multicast Virtual Routing and Forwarding (VRF) Lite: VRF Lite allows the customer to

configure multiple private routing domains for network virtualization and virtual private

networks. Multicast support has now been added to VRF Lite allowing multicast traffic per

VRF.

●

Internet Group Management Protocol (IGMP) Proxy: This capability allows the switch to

forward a host’s request to join a multicast stream to a specific IP destination address.
