Chapter
OL-23826-08 July 2013 • Autonomic Networking—Autonomic networking is
supported from Cisco IOS Release 15.3(2)S onwards. It
makes devices more intelligent and simplifies the interface
between the operator and Network Management System
(NMS) system, by providing a strong abstraction across the
network, distributed on each device. It also automatically
provides all relevant best practices, and keeps them up to
date, without the need for human intervention.
• Storm Control—The Storm Control feature prevents traffic
on a LAN from being disrupted by a broadcast, multicast, or
unknown unicast storm on one of a port.
• Egress Policing—Egress policing can be classified based on
QoS-groups, DSCP, and precedence value. For QoS-groups
to work at egress, you should map the traffic at ingress to a
specific QoS-group value.
• MPLS Traffic Engineering (TE)—Fast Reroute (FRR) Link
Protection—Support for CESoPSN, SAToP, and ATM/IMA
was added from Cisco IOS Release 15.3(3)S onwards.
• Multiaction Ingress Policer on EVC—Effective with Cisco
IOS Release 15.3(3)S, the Cisco ASR 901 supports policing
ingress traffic over the cross connect EVC, similar to bridge
domain service policy.
• Y.1731 Performance Monitoring—Effective with Cisco IOS
Release 15.3(3)S, the Cisco ASR 901 router supports ITU-T
Y.1731 performance monitoring on the following interfaces:
–
SLM support on the EVC cross connect
–
SLM support on the Port-Channel EVC cross connect
–
DMM and SLM support on the EVC BD for both the up
and down MEPs
–
SLM support on the EVC cross connect for both the up
and down MEPs
• RFC 3107 Labeled BGP Support for TDM Pseudowire—The
RFC 3105 labeled BGP is supported for TDM pseudowire
from Cisco IOS Release 15.3(3)S onwards.
• Support for Digital Optical Monitoring (DOM) for 10 Gig
Optics—Effective with Cisco IOS Release 15.3(3)S, Cisco
ASR 901 supports DOM for both 1G and 10G SFPs.
