The BFD session view is displayed.
Step 3
Run:
process-pst
The BFD is permitted to modify the PST.
By default, the BFD does not modify the PST.
NOTE
l
The
process-pst
command cannot be configured on logical interfaces, such as Eth-Trunk and VLANIF
interfaces.
l
After creating a BFD session, if you need to modify session parameters such as
process-pst
,
process-
interface-status
,
min-tx-interval
,
min-rx-interval
,
detect-multiplier
,
tos-exp (BFD session view)
,
wtr
, and
description
, you can directly run the corresponding commands without running the
commit
command, and the modification takes effect immediately.
If the BFD session on the Trunk member interface or the VLAN member interface allows BFD
to modify the PST, and the main interface is configured with the BFD session, you must configure
the Wait to Recovery (WTR) for the BFD session that detects the main interface. This can prevent
the BFD session on the main interface from flapping when the member interface joins or exits
from the main interface.
For the configuration of the WTR for the BFD session, see "
."
Step 4
Run:
commit
The configurations are committed.
----End
5.6.3 Checking the Configurations
