config loopdetect
Purpose Used to configure the loopback detection function on the Switch.
Syntax config loopdetect { recover_timer [ 0 | <value 60-1000000> ] | interval < value 1-32767> }(1)
Description This command is used to set up the loopback detection function (LBD) for the entire Switch.
Parameters
recover_timer - The time interval (in seconds) used by the Auto-Recovery mechanism to decide
how long to check if the loop status is gone. Zero is a special value which means to disable the
auto-recovery mechanism, hence, a user needs to recover the disabled port back manually. The
default value of the recover timer is 60. The valid range is 60 to 1000000.
interval - The time interval (in seconds) at which a device transmits all the CTP (Configuration Test
Protocol) packets to detect the loopback event. The valid range is 1 to 32767. The default setting
is 10.
Restrictions
Only Administrator level, Operator level or Power User level users can issue this command.
Example usage:
To set a recover time of 0 with an interval of 20:
DES-1228/ME:5# config loopdetect recover_timer 0 interval 20
Command: config loopdetect recover_timer 0 interval 20
Success.
