Configuring CDP

Setting the CDP Message Interval

The CDP message interval specifies how often the switch will transmit CDP messages to directly
connected Cisco devices.
To change the default CDP message interval, perform this task in privileged mode:
Task
Step 1 Change the default CDP message interval. The
allowed range is 5–900 seconds.
Step 2
Verify the CDP configuration.
This example shows how to change the default CDP message interval to 100 seconds and verify the
configuration:
Console> (enable) set cdp interval 100
CDP message interval set to 100 seconds for all ports.
Console> (enable) show cdp

Setting the CDP Holdtime

The CDP holdtime specifies how much time can pass between CDP messages from neighboring devices
before the device is no longer considered connected and the neighbor entry is aged out.
To change the default CDP holdtime, perform this task in privileged mode:
Task
Step 1
Change the default CDP holdtime. The allowed
range is 10–255 seconds.
Step 2
Verify the CDP configuration.
This example shows how to change the default CDP holdtime to 225 seconds and verify the
configuration:
Console> (enable) set cdp holdtime 225
CDP holdtime set to 225 seconds.
Console> (enable) show cdp
