User Manual

[Initial value]
None
[Input mode]
global configuration mode
[Description]
Normally, Blocking is released immediately when the loop is cleared.
When this command is configured, it detects if the loop is cleared at regular intervals.
If the loop is cleared, Blocking is released, but if the loop is not cleared, Blocking continues until that time passes again.
If this command is executed with the "no" syntax, the setting returns to the default.
[Note]
If a port in the Port Blocking state goes link down, the Port Blocking is removed immediately.
[Example]
Set the Port Blocking loop clearing detection interval to 300 seconds.
SWP2(config)#loop-detect blocking interval 300
