DES-3000 Series Layer 2 Switch CLI Reference Manual
DES-3026:4#disable loopdetect
Command: disable loopdetect
Success.
DES-3026:4#
config loopdetect
Purpose
Used to configure the Loopback Detection function parameters on
the switch.
Syntax
config loopdetect [recover_timer [0 | <value 60-1000000>] |
interval <value 1-32767>]
Description
This command is used to set the parameters for the Loopback
Detection function on the switch, without adjusting configurations.
The Loopback Detection function is used to identify loops occurring
between the Switch and a device that is directly connected to it. The
Loopback Detection function will disable a port that has a loop until
the anomaly has ceased, and the loopback occurrence will be noted
in the Switch’s log. Once the loopback problem has stopped, this
port will be automatically recovered in a time period that can also be
specified by the user.
Parameters
recover_timer [0 | <value 60-1000000>]
- Enter a time, in seconds
that a port will have to wait before being recovered from a Loopback
Detection shutdown. The user may set a time between 60 and
1000000 seconds with a default setting of 60 seconds. The user
may also enter a time of 0 which means that the port can only be
recovered manually by the user. This is done by configuring the
config ports
command and manually enabling these ports.
interval <value 1-32767>
- Enter a time interval, between 1 and
32767 seconds, that CTP (Configuration Testing Protocol) packets
will be dispatched from Loopback Detection enabled ports. If this
packet is returned, the port will be disabled. The default setting is 10
seconds.
Restrictions Only
administrator-level users can issue this command.
Example usage:
To configure the loopback detection recover timer:
DES-3026:4#config loopdetect recover_timer 60
Command: config loopdetect recover_timer 60
Success.
DES-3026:4#
Example usage:
To configure the loopback detection CTP packet interval:
DES-3026:4#config loopdetect interval 10
