Chapter C Commands
carrier-delay
To set the carrier delay on a serial interface, use the carrier-delay command. To return to the default
carrier delay value, use the no form of this command.
Syntax Description
delay-seconds
msec
milliseconds
Command Default None
Command Modes Interface configuration mode
Command History Release
5.2(1)N1(1)
Usage Guidelines You can use this command on a VLAN interface.
If a link goes down and comes back up before the carrier delay timer expires, the down state is effectively
filtered, and the rest of the software on the switch is not aware that a link-down event occurred.
Therefore, a large carrier delay timer results in fewer link-up/link-down events being detected. Setting
the carrier delay time to 0 means that every link-up/link-down event is detected.
This command does not require a license.
Examples This example shows how to change the carrier delay to 10 seconds:
switch# configure terminal
switch(config)# interface vlan 5
switch(config-if)# carrier-delay 10
switch(config-if)#
This example shows how to revert to the default carrier delay value:
switch# configure terminal
switch(config)# interface vlan 5
switch(config-if)# no carrier-delay
switch(config-if)#
