Checking the Configurations
After the configuration is complete, perform the following operation to verify that the
configuration is correct.
Run the display oam-bandwidth slot slot-id command to check the OAM bandwidth
consumption. For example:
[HUAWEI] display oam-bandwidth slot 2
OAM bandwidth information on slot 2:
Current tx bandwidth is 0 bps
Current rx bandwidth is 0 bps
Max bandwidth is 2850000000 bps
Free bandwidth is 2850000000 bps
Bandwidth alarm threshold is 80%
Bandwidth exceed threshold: NO
OAM bandwidth detail information on slot 2:
EOAM-1ag bandwidth-usage info:
Session tx total bandwidth is: 0 bps
Session rx total bandwidth is: 0 bps
BFD bandwidth-usage info:

Session rx total bandwidth is: 0 bps
MPLS-TP OAM bandwidth-usage info:
Session tx total bandwidth is: 0 bps
Session rx total bandwidth is: 0 bps
MQE bandwidth-usage info:
Session tx total bandwidth is: 0 bps
Session rx total bandwidth is: 0 bps

8.2.13 Associating CFM with VRRP

When the Virtual Router Redundancy Protocol (VRRP) is used for device-level reliability in
dual-homing network, connectivity fault management (CFM) can be associated with it to resolve
the dual-master problem that may temporarily occur if a link failure.
Context
As networks are increasingly popular and new applications emerge, diversified value-added
services such as Internet Protocol Television (IPTV) and video conferencing, are widely
deployed. Services in a network may be affected to cause a great loss when the network is
interrupted. Carriers are paying greater attention to network reliability. If an interruption occurs,
the VAS service is adversely affected. Protection switching and fault detection technologies are
usually combined to improve network reliability.
As shown in
edges (NPEs), NPE1 and NPE2 through two links. Between the two links, one is a working link
and the other is a protection link. NPE1 and NPE2 back up each other. CFM is deployed between
