Loopback Detection Commands
Extreme Networks EAS 100-24t Switch CLI Manual
143
Each command is listed, in detail, in the following sections:
Example usage:
To set a recover time of 0 with an interval of 20:
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>}
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 users can issue this command.
#config loopdetect recover_timer 0 interval 20
Command: config loopdetect recover_timer 0 interval 20
Success.
