shutdown-time

Specifies the time a port will be disabled after Edge Loop Detection (ELD) detects a loop.

Synopsis

shutdown-time num

no shutdown-time num

Operands

num

Specifies the number of minutes before a port is re-enabled. Valid values
range from 10 through 1440 minutes (10 minutes to 24 hours).

Defaults

The default value is 0 minutes.

The port will not be re-enabled automatically.

Command Modes

ELD configuration mode

Description

Use this command to set the delay between ELD shutting down a port because it has detected a
loop and automatically re-enabling that port.

NOTE

Any change to shutdown-time only takes effect for the ports that are disabled by ELD after the
configuration change. Any ports that were already disabled by ELD before the shutdown-time
change continues to follow the old shutdown-time value. These ports start to follow the new
shutdown time after the currently running timer expires and ELD still detects the loop and shuts
down the port again.

Usage Guidelines

If you do not set a shutdown time using this command, you can re-enable all ELD-disabled ports
manually using the clear edge-loop-detection command.

Enter no shutdown-time to return to the default value.

Examples

To re-enable ports 24 hours after they are disabled by ELD:

switch(config)# protocol edge-loop-detection

switch(config-eld)# shutdown-time 1440

To cancel automatic port re-enable:

switch(config-eld)# no shutdown-time 1440
