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
Use this command to enable the DHCP Layer 2 Relay agent for an interface, a range of
interfaces, or all interfaces. The subsequent commands mentioned in this section can be
used only when the DHCP L2 relay is enabled.

Term Definition
A unicast MAC address for which the switch has forwarding and or filtering information.
As the data is gleaned from the MFDB, the address will be a multicast address. The
format is 6 or 8 two-digit hexadecimal numbers that are separated by colons, for example
01:23:45:67:89:AB. In an IVL system the MAC address will be displayed as 8 bytes.
The type of the entry. Static entries are those that are configured by the end user.
Dynamic entries are added to the table as a result of a learning process or protocol.
The text description of this multicast table entry.
The list of interfaces that are designated for forwarding (Fwd:) and filtering (Flt:).
