set cdp auth
10-4 Discovery Protocol Configuration
set cdp auth
Use this command to set a global CDP authentication code.
Syntax
set cdp auth auth-code
Parameters
Defaults
None.
Mode
Switch command, read-write.
Usage
The authentication code value determines a switch’s CDP domain. If two or more switches have
the same CDP authentication code, they will be entered into each other’s CDP neighbor tables. If
they have different authentication codes, they are in different domains and will not be entered
into each other’s CDP neighbor tables.
A switch with the default authentication code (16 null characters) will recognize all switches, no
matter what their authentication code, and enter them into its CDP neighbor table.
Example
This example shows how to set the CDP authentication code to 1,2,3,4,5,6,7,8:
C3(su)->set cdp auth 1,2,3,4,5,6,7,8:
set cdp interval
