process-pst

Function

The process-pst command enables the system to modify the port status table (PST) when the BFD session status changes.

The undo process-pst command restores the default configuration.

By default, the device is disabled from modifying the PST.

Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support this command.

Usage Guidelines

Usage Scenario

After a BFD session that is enabled to modify the PST detects a BFD session Down event, the system modifies the corresponding entry in the PST.

Precautions

You can only run the process-pst command in the BFD session view that is bound to LDP LSP, Static LSP, or MPLS TE.
When configuring static BFD-based LDP FRR, you must configure the process-pst command.
When configuring static BFD for CR-LSP and static BFD for TE, you must configure the process-pst command.
For applications in which a fault detected by BFD is not sensed through the PST, you do not need to configure the process-pst command.
In IP FRR scenarios, the PST function is automatically enabled for dynamic BFD sessions but cannot be configured for IP static BFD sessions bound to the same interface.

Example

# Enable the system to modify the PST when the BFD session status changes.
