The Loopback Detection commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the
following table.
Command
Parameters
config loopdetect
{ recover_timer [0 | <value 60-1000000>] | interval <value 1-32767>}(1)
config loopdetect ports
[<portlist> | all] state [enable | disable]
enable loopdetect
disable loopdetect
show loopdetect
show loopdetect ports
[<portlist> | all]
Each command is listed, in detail, in the following sections.
config loopdetect
Purpose
Used to configure loopback detection on the switch.
Syntax
config loopdetect { recover_timer [0 | <value 60-1000000>] | interval <value 1-
32767>}(1)
Description
Used to configure loopback detection on the 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. The valid range is
60
to
1000000
. Zero
is a special value which means to disable the auto-recovery mechanism. The default value is
60
.
interval –
The time interval (in seconds) at which the remote device transmits all the CTP
packets to detect the loopback event. The default value is
10
, with a valid range of
1
to
32767
.
Restrictions
Only Administrator-level users can issue this command.
Example usage:
To set the recover time to 0, and interval to 20:
DES-1228/ME:4#config loopdetect recover_timer 0 interval 20
Command: config loopdetect recover_timer 0 interval 20
Success
DES-1228/ME:4#
