switch# configure terminal
switch(config)# no feature udld
Configuring Interface Speed
If the interface and transceiver speed is mismatched, the SFP validation failed message is displayed when
Note
you enter the show interface ethernet slot/port command. For example, if you insert a 1-Gigabit SFP
transceiver into a port without configuring the speed 1000 command, you will get this error. By default,
all ports are 10 Gigabits.
SUMMARY STEPS
1. switch# configure terminal
2. switch(config)# interface type slot/port
3. switch(config-if)# speed speed
DETAILED STEPS
Command or Action
Step 1
switch# configure terminal
Step 2
switch(config)# interface type slot/port
Step 3

switch(config)# interface ethernet 1/4
switch(config-if)# speed 1000
Disabling Link Negotiation
You can disable link negotiation using the no negotiate auto command. By default, auto-negotiation is enabled
