OSCP Commands
oscp timer hello interval
To modify the OSCP timer Hello interval, use the oscp timer hello interval command. To return the
Hello interval to its default value, use the no form of the command.
oscp timer hello interval milliseconds
no oscp timer hello interval
Syntax Description
Defaults 100 milliseconds
Command Modes Global configuration
Command History
Usage Guidelines Use this command to control how often OSCP Hello messages are sent. The OSCP sends Hello packets
to adjacent nodes at a configured interval. When five packets fail to get a response from the receiving
node, that node is declared “down.” By decreasing the interval at which Hello packets are sent, reaction
time to a failed node can be lessened. Increasing the interval reduces the amount of Hello packet traffic.
Note There is a trade-off between the frequency of generati ng He llo pac kets a nd the sp ee d i n wh ic h t he
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 configure the OSCP timer Hello interval.
Switch# configure terminal
Switch(config)# oscp timer hello interval 200
