The definition of Circuit ID in the switch is 4 bytes in length and the format is "vlan_id" "module_id" "port_no". The parameter of
"vlan_id" is the first two bytes representing the VLAN ID. The parameter of "module_id" is the third byte for the module ID (in
standalone switch it always equals 0; in stackable switch it means switch ID). The parameter of "port_no" is the fourth byte and it
means the port number.
The Remote ID is 6 bytes in length, and the value equals the DHCP relay agent’s MAC address. The DHCP Relay Configuration
screen in Figure 4-2-11 appears.
Figure 4-2-11 DHCP Relay Configuration page Screenshot
The page includes the following fields:
Object Description
• Relay Mode
Indicates the DHCP relay mode operation. Possible modes are:
Enabled: Enable DHCP relay mode operation. When enabling DHCP relay
mode operation, the agent forwards and transfers DHCP messages between
the clients and the server when they are not on the same subnet domain.
And the DHCP broadcast message won't flood for security considered.
Disabled: Disable DHCP relay mode operation.
• Relay Server
Indicates the DHCP relay server IP address. A DHCP relay agent is used to
forward and transfer DHCP messages between the clients and the server when
they are not on the same subnet domain.
• Relay Information
Mode
Indicates the DHCP relay information mode option operation. Possible modes
are:
Enabled: Enable DHCP relay information mode operation. When enabling
DHCP relay information mode operation, the agent inserts specific
information (option82) into a DHCP message when forwarding to DHCP
server and removing it from a DHCP message when transferring to DHCP
client. It only works under DHCP relay operation mode enabled.
Disabled: Disable DHCP relay information mode operation.
• Relay Information
Policy
Indicates the DHCP relay information option policy. When enabling DHCP relay
information mode operation, if agent receives a DHCP message that already
contains relay agent information. It will enforce the policy. And it only works under
DHCP relay information operation mode enabled. Possible policies are:
