Configures PSC/PSC2 task failure detection speed.

Privilege
Security Administrator, Administrator
Syntax
Default:
: Initiates PSC failover without performing additional checks.
: Initiates PSC failover after additional checks are performed.
Usage
Use this command to increase the fault detection speed for faster switchovers after a PSC/PSC2 task failure.
Setting fault detection speed to aggressive will trigger PSC/PSC2 failover as soon as possible if a potential
failure is detected. Aggressive mode will reduce the duration of subscriber outages caused by a failed
PSC/PSC2 if session recovery is enabled.
Aggressive mode also bypasses most information gathering steps and logs that can be used to determine the
root cause of the failure.
In normal mode, additional checks are performed before triggering a PSC/PSC2 failover to ensure the card
has actually failed. In aggressive mode these checks are bypassed so that session recovery can start as soon as
possible. These additional checks reduce the likelihood of a false positive failure.
