New Software Features in Cisco IOS XE Release 3.11S

AAL5 termination

This feature enables the Asynchronous Transfer Mode Adaptation Layer 5 (AAL5) layer 3 termination

on the interface module (IM) (T1/E1 and OC-3) cards on the Cisco ASR 903 Router.

For more information see,

03.html

Access Switch Device Manager Template

This feature can be used to configure system resources on the router to optimize support for specific

features, depending on how the router is used in the network.

Data Plane Ethernet Loopback with QoS

The Ethernet data plane loopback feature provides a means for remotely testing the throughput of an

Ethernet port. For more information see,

http://www.cisco.com/en/US/docs/routers/asr903/software/guide/b_layer2_ASR903_chapter_00.html.

Dissimilar PHB Match at Ingress and Egress

The dissimilar per-hop behavior (PHB) match on exp is supported for Ingress and Egress on MPLS and

VPLS interfaces.

In earlier releases prior to Cisco IOS XE Release 3.11S, when qos-group or discard-class based on exp

classification was configured, Egress based classification was not allowed on any other classification

except Ingress set qos-group or discard-class. This was due to the PHB security model.

With Cisco IOS Release 3.11, only EVC based tunnel type configuration with either Layer2 VPN or

Layer3 VPN is supported.
