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.
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
WTR."
Step 4 Run:
commit
The configurations are committed.

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.
Run the display bfd session { all | discriminator discr-value | dynamic | peer-ip peer-
ip [ vpn-instance vpn-instance-name ] | static } [ verbose ] [ slot slot-id ] command to
check the BFD session.
Run the display bfd session { all | static | peer-ipv6 peer-ipv6 [ vpn-instance vpn-instance-
name ] } [ verbose ] [ slot slot-id ] command to check information about the BFD6 session.
