Loopback Detection Commands - D-Link xStack DES-3500 Series Manual

These commands are used to configure, conduct and display the results of loopback detection by the switch.
The Loopback Detection commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the
following table.
Command
config loopdetect
config loopdetect ports
enable loopdetect
disable loopdetect
show loopdetect
show loopdetect ports
Each command is listed, in detail, in the following sections.
config loopdetect
Purpose

Example usage:
To set recover_time to 0, and interval to 20, and vlan-based mode:
DES-3526:admin#config loopdetect recover_timer 0
interval 20 vlan-based
Command: config loopdetect recover_timer 0 interval 20
vlan-based
Success
DES-3526:admin#
DES-3500 Layer 2 Fast Ethernet Switch CLI Reference Manual
Parameters
{recover_timer [0| <value 60-1000000>] | interval <1-32767> | mode
[port-based | vlan-based]}
[<portlist> | all] state [enable | disable]
[<portlist> | all]
Used to configure loop-back detection on the switch.
config loopdetect {recover_timer [0| <value 60-1000000>] | interval <1-
32767> | mode [port-based | vlan-based]}
Used to configure loop-back detection on the switch.
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 (inseconds) at which the remote device
transmits all the CTP packets to detect the loop-back event. The default
value is 10, with a valid range of 1 to 32767,
mode – In port-based mode, the port will be disabled during the loop
detection. In vlan-based mode, the port can not porcess VLAN packets
destined for ports involved in detecting the loop.
Only Administrator and Operator-level users can issue this command.
