Chapter 2 Configuring Basic Interface Parameters
Configuring the Basic Interface Parameters
This example shows how to enable the UDLD for the device:
switch# configure terminal
switch(config)# feature udld
switch(config)#
This example shows how to set the UDLD message interval to 30 seconds:
switch# configure terminal
switch(config)# feature udld
switch(config)# udld message-time 30
switch(config)#
This example shows how to enable the aggressive UDLD mode for fiber interfaces:
switch# configure terminal
switch(config)# feature udld
switch(config)# udld aggressive
switch(config)#
This example shows how to enable the aggressive UDLD mode for the copper interface Ethernet 3/1:
switch# configure terminal
switch(config)# feature udld
switch(config)# udld aggressive
switch(config)# interface ethernet 3/1
switch(config-if-range)# udld enable
switch(config-if-range)#
This example shows how to disable UDLD for Ethernet port 3/1:
switch# configure terminal
switch(config)# interface ethernet 3/1
switch(config-if-range)# no udld enable
switch(config-if-range)# exit
This example shows how to disable UDLD for the device:
switch# configure terminal
switch(config)# no feature udld
switch(config)# exit
Configuring the Carrier Delay Timer
The carrier delay timer sets a time during which all link-down/link-up events are not detected by any of
the other software on the device. When you configure a longer carrier delay time, fewer
link-down/link-up events are recorded. When you configure the carrier delay time to 0, the device detects
each link-down/link-up event.
Step 8
exit
Example:
switch(config-if-range)# exit
switch(config)#
Exits the interface mode.
Step 9
copy running-config startup-config
Example:
switch(config)# copy running-config startup-config
(Optional) Copies the running
configuration to the startup
configuration.
