config loopdetect
Description
This command is used to setup the loop-back detection function (LBD) for the entire switch.
Format
config loopdetect {recover_timer [<value 0> | <sec 60-1000000>] | interval
<sec 1-32767> | mode [port-based]}
Parameters
●
recover_timer - (Optional) The time interval (in seconds) used by the Auto-Recovery mechanism to
decide how long to check before determining that the loop status has gone. The valid range is from
60 to 1000000. 0 is a special value that specifies that the auto-recovery mechanism should be
disabled. When the auto-recovery mechanism is disabled, a user would need to manually recover a
disabled port. The default value for the recover timer is 60 seconds.
●
<value 0> - 0 is a special value that specifies that the auto-recovery mechanism should be
disabled. When the auto-recovery mechanism is disabled, a user would need to manually recover
a disabled port.
●
<sec 60-1000000> - Enter the recovery timer value here. This value must be between 60 and
1000000 seconds.
●
interval - (Optional) The time interval (in seconds) that the device will transmit all the CTP
(Configuration Test Protocol) packets to detect a loop-back event. The default setting is 10 seconds.
The valid range is from 1 to 32767 seconds.
●
<sec - 1-32767> - Enter the time interval value here. This value must be between 1 and 32767
seconds.
●
mode - (Optional) Specify the loop-detection operation mode. In port-based mode, the port will be
shut down (disabled) when loop has been detected In VLAN-based mode, the port cannot process
the packets of the VLAN that has detected the loop.
●
port-based - Specifies that the loop-detection operation mode will be set to port-based mode.
