New Software Features in Cisco IOS XE Release 3.11S
AAL5 termination

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

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.
