Checking The Configuration - Huawei AR2200-S Series Configuration Manual

Huawei AR2200-S Series Enterprise Routers
Configuration Guide - Reliability
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
bfd
interface-type interface-number [ source-ip source-ip ] one-arm-echo
A BFD session with the one-arm Echo function is created.
Step 3 Run:
discriminator local discr-value
The discriminator is set for the BFD session that one-arm Echo function configured.
The one-arm Echo function can be configured only on the BFD-capable device at one end of a
link. A BFD session with this function must be configured with a local discriminator rather than
a remote discriminator.
Step 4 (Optional) Run:
min-echo-rx-interval interval
The minimum interval between receipt of BFD packets is set.
By default, the minimum interval between receipt of BFD packets is 10 milliseconds.
Step 5 Run:
commit
The configuration is committed.

3.6.4 Checking the Configuration

By viewing the type and status of a BFD session with the one-arm Echo function, you can check
whether the configurations are correct.
Prerequisite
The configurations of the one-arm Echo function are complete.
Issue 01 (2012-01-06)
cfg-name bind peer-ip peer-ip [ vpn-instance vpn-instance-name ] interface
NOTE
l A BFD session with the one-arm Echo function can detect only single-hop links.
l A BFD session currently does not detect route switching. If the change of bound peer IP address causes
a route to switch to another link, the BFD session is negotiated again only when the original link fails.
NOTE
After configuring the local discriminator parameter and any other required parameters for a BFD session
with the one-arm Echo function, you must run the commit command to make the configuration take effect.
