Configuring The Cdp Characteristics - Cisco Nexus 5000 Series Configuration Manual

Configuring the CDP Characteristics

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-if)# speed speed
The following example shows how to set the speed for a 1-Gigabit Ethernet port:
switch# configure terminal
switch(config)# interface ethernet 1/4
switch(config-if)# speed 1000
This command can only be applied to a physical Ethernet interface.
Note If the interface and transceiver speed is mismatched, the SFP validation failed message is displayed when
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.
Configuring the CDP Characteristics
You can configure the frequency of Cisco Discovery Protocol (CDP) updates, the amount of time to hold the
information before discarding it, and whether or not to send Version-2 advertisements.
To configure CDP characteristics for an interface, perform this task:
SUMMARY STEPS
1. switch# configure terminal
2. (Optional) switch(config)# [no] cdp advertise {v1 | v2 }
3. (Optional) switch(config)# [no] cdp format device-id {mac-address | serial-number | system-name}
4. (Optional) switch(config)# [no] cdp holdtime seconds
5. (Optional) switch(config)# [no] cdp timer seconds
