Cisco ASR 901 Series Aggregation Services Router Software Configuration Guide
OL-23826-09
Chapter
OL-23826-09 November 2013 • 1588v2 Hybrid Clock—To improve the clock quality, you
can either improve the oscillator class or reduce the number
of hops between the master and the slave. In PTP hybrid
mode, the oscillator class is improved by using a physical
layer clock (sourced from a stratum-1 clock) instead of the
available internal oscillator. The PTP hybrid mode is
supported for ordinary clock (in slave mode only) and
boundary clock.
• Dual REP Edge No-Neighbor—Effective with Cisco IOS
release 15.4.(1)S, you can configure the non-REP switch
facing ports on a single device as dual edge no-neighbor
ports. These ports inherit all properties of edge ports, and
overcome the limitation of not converging quickly during a
failure.
• EoMPLS/TDM Pseudowire Redundancy over
FRR—Effective with Cisco IOS Release 15.4(1)S, support
was added for EoMPLS/TDM pseudowire redundancy over
FRR.
• Ethernet loopback (NOSTG CLI and terminal loopback
)—Effective with Cisco IOS Release 15.4(1)S, the Cisco
ASR 901 supports internal loopback on Bridge-domain
EFPs.
• IPv4 Multicast—Describes how to configure IP multicast in
an IPv4 network. IP multicast is an efficient way to use
network resources, especially for bandwidth-intensive
services such as audio and video.
• IPv6 Multicast—Describes how to configure basic IP
multicast in an IPv6 network.
• Extending QoS over MLPPP Interface—Effective with
Cisco IOS Release 15.4(1)S, the QoS functionality on the
MLPPP interface is extended to support:
–
QoS for MPLS over MLPPP
–
QoS for CPU generated traffic
• Redundant PTP instances as per G.8265.1—PTP redundancy
is an implementation on different clock nodes by which the
PTP slave clock node interacts with multiple master ports
such as grand master, boundary clock nodes, and so on. A
new servo mode is defined under PTP to support high PDV
scenarios (when the PDVs exceed G.8261 standard profiles).
