DHCP L2 Relay Agent Commands
You can enable the switch to operate as a DHCP Layer 2 relay agent to relay DHCP requests from clients to a
Layer 3 relay agent or server. The Circuit ID and Remote ID can be added to DHCP requests relayed from clients
to a DHCP server. This information is included in DHCP Option 82, as specified in sections 3.1 and 3.2 of
RFC3046.
dhcp l2relay
This command enables the DHCP Layer 2 Relay agent for an interface a range of interfaces in, or all interfaces.
The subsequent commands mentioned in this section can only be used when the DHCP L2 relay is enabled.
no dhcp l2relay
This command disables DHCP Layer 2 relay agent for an interface or range of interfaces.
dhcp l2relay circuit-id subscription
This command sets the Option-82 Circuit ID for a given service subscription identified by subscription-string
on a given interface. The
subscription-string is a character string which needs to be matched with a
configured DOT1AD subscription string for correct operation. When circuit-id is enabled using this command,
all Client DHCP requests that fall under this service subscription are added with Option-82 circuit-id as the
incoming interface number.
no dhcp l2relay circuit-id subscription
This command resets the Option-82 Circuit ID for a given service subscription identified by subscription-string
on a given interface. The
subscription-string is a character string which needs to be matched with a
configured DOT1AD subscription string for correct operation. When circuit-id is disabled using this command,
all Client DHCP requests that fall under this service subscription are no longer added with Option-82 circuit-id.
