LOOPBACK INTERFACE COMMANDS

The Loopback Interface 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 | <sec 60-1000000>] | interval <sec 1-32767> | mode [port-

based | vlan-based]}(1)

config loopdetect ports

[<portlist> | all] state [enable | disable]

enable loopdetect

disable loopdetect

show loopdetect

show loopdetect ports

{<portlist>}

config loopdetect trap

[none | loop_detected | loop_cleared | both]

Each command is listed, in detail, in the following sections.

config loopdetect

Purpose

This command is used to setup the loop-back detection function (LBD) for the entire Switch.

±

Syntax

config loopdetect {recover_timer [0 | <sec 60-1000000>] | interval <sec 1-32767> |

mode [port-based | vlan-based]}(1)

Description

This command is used to setup the loop-back detection function (LBD) for the entire Switch.

±

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.

0

- Specifies that the value of 0 will be set to the recovery timer.

<

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.

vlan-based

- Specifies that the loop-detection operation mode will be set to vlan-based mode.

Restrictions

Only Administrator and Operator-level users can issue this command.

Example usage:

429

To set the auto-recover time to 0, which disables the auto-recovery mechanism, the interval to 20 seconds and specify

VLAN-based mode:

DGS-3627:admin#

config loopdetect recover_timer 0 interval 20 vlan-based

Command: config loopdetect

recover_timer 0 interval 20 vlan-based

Success.

DGS-3627:admin#

config loopdetect ports

Purpose

This command is used to setup the loop-back detection function for the interfaces on the

Switch.

Syntax

config loopdetect ports [<portlist> | all] state [enable | disable]

Description

This command is used to setup the loop-back detection function for the interfaces on the

Switch.

Parameters

ports

- Specify the range of ports that LBD will be configured on.

<

portlist

> - Enter a list of ports

all

- To set all ports in the system, you may use the “all” parameter.

state

- Specify whether the LBD function should be enabled or disabled on the ports specified

in the port list. The default state is disabled.

enable

- Specify to enable the LBD function.

disable
