Usage Information

The show ipv6 dhcp-relay command displays the following information: 

Interface name
Per-interface interface-id field value
Per-interface remote-id field value
Per-interface source-interface field value

show ipv6 dhcp relay interface <interface> - This command displays the relay information for the requested interface.

If the interface-id option is enabled, the show command displays the option-18 value which is sent in packet Format:- interface-id (or) prefix:interface-id (if prefix is configured)

If the remote-id option is enabled, the show command displays the option-37 value which is sent in packet format:- remote-id (or) prefix:remote-id (if prefix is configured)

If interface-id option is disabled, the corresponding show command field displays Disabled.

If remote-id option is disabled, the corresponding show command field displays Disabled.

If source interface is configured with IP address, the corresponding show command field displays source-interface IP address.

If the source interface is configured without any IP address, the corresponding show command field displays that the source-interface IP address is not configured.

If source interface is not configured, the corresponding show command field displays that the source-interface is not configured.

If an interface is associated to a VLAN, then it is mandatory to give both VLAN and port information in the show command. For example, show ipv6 dhcp-relay vlan 10 ethernet 1/1/1. Otherwise, the show command displays an empty output.

NOTE: If an interface is associated with a VLAN, then you must specify both the VLAN and port information in the show command. For example, show ipv6 dhcp-relay vlan 10 ethernet 1/1/1. Otherwise, the show command displays empty output.
NOTE: This command is accessible to all user roles.
