OSCP Commands
oscp timer inactivity-factor
To modify the OSCP timer Hello inactivity factor, use the oscp timer inactivity-factor command. To
return the Hello inactivity factor to its default value, use the no form of the command.

Syntax Description
Defaults 5 seconds
Command Modes Global configuration
Command History
Usage Guidelines The system uses this attribute to determine when a neighbor node, or the link to it, has gone down. The
link to a neighbor node is considered inactive if an OSCP Hello packet is not received for a time interval
determined by the inactivity factor. The time interval is calculated by multiplying the inactivity factor
by the advertised hold-down interval. For example, if the neighbor node’s advertised hold-down interval
is 5 seconds and the local node’s inactivity factor is 5, the time interval that the local node will wait until
declaring the neighbor node down is 25 seconds.
Note There is a trade-off between the frequency of generating Hello packets and the speed in which the
system detects that the OSCP has gone down. In certain OSCP failure scenarios, a shorter Hello
interval leads to faster detection of the OSCP failure.
Examples The following example shows how to set the OSCP timer Hello inactivity factor to 3.
Switch# configure terminal
Switch(config)# oscp timer inactivity-interval 3
Related Commands
factor Specifies a value used to calculate an inactivity interval. The specified
interval of time is equal to the inactivity factor multiplied by the neighbor’s
advertised Hello interval. The range is 1 to 50.
