Monitoring DHCP Option 60 Information

Purpose

Display configuration and action information for the DHCP vendor-option (option 60) feature.

Use the command without additional keywords to display information for all vendor option configurations.
Use the vendor-option-relay-server keyword and server address to display information for option 60 strings that match a configured string that results in the packets being sent to the specified vendor-option server.
Use the default keyword to display information for option 60 strings that do not match a configured vendor-option string.

Action

To display information for all vendor option configurations:

host1#show dhcp vendor-option 
Codes:
 *       - the configured vendor-string is an exact-match
 default - all DHCP client packets not matching a configured vendor-string
 implied - the DHCP application is configured but has not been enabled
           with the vendor-option command
 drop    - the DHCP application responsible for the action has not been
           configured yet therefore all packets for this application
           will be dropped
 Total 4 entries.
