Configuring VPP Monitor on Active UPF and Standby UPF
Use the following configuration to configure Vector Packet Processing (VPP) monitor to trigger UPF switchover on the Active UPF if VPP goes down. This command is configured in the SRP Configuration Mode.
configure
context context_name
service-redundancy-protocol
monitor system vpp delay-period seconds
end
NOTES:
-
If previously configured, use the no monitor system vpp CLI command to disable VPP monitoring on the Active and Standby UPF.
-
vpp delay-period seconds : Specifies the delay period in seconds for a switchover, after a VPP failure. seconds must be in the range of 0 through 300.
If the delay period is a value greater than zero (0), then the switchover is initiated after the specified delay period when VPP fails. The last VPP status notification within the delay period is the final trigger for switchover action. The default value is 0 seconds, which initiates an immediate switchover.
The need for delay is to address the scenario wherein the VPP is temporarily down and the revival is in process. This implies that a switchover may not be necessary.

This command is disabled by default.
