8.1 DHCP Relay Agent
This dialog allows you to configure the DHCP relay agent.
Enter the DHCP server IP address.
If one DHCP server is not available, you can enter up to 3 additional
DHCP server IP addresses so that the device can change to another
DHCP server.
With Option 82, a DHCP relay agent which receives a DHCP request
adds an “Option 82” field to the request, as long as the request received
does not already have such a field.
When the function is switched off, the device will forward attached “Option
82” fields, but it will not add any on. Under “Type”, you specify the format
in which the device recognition of this device is entered in the “Option 82”
field by the DHCP relay agent.
The options are:
– IP address
– MAC Address (state on delivery)
– System name (client ID)
– Other (freely definable ID, which you can specify in the following rows).
“Remote ID entry for DHCP server” shows you the value which you enter
when configuring your DHCP server. “Type display” shows the device
recognition in the selected form.
The “Circuit ID” column in the table shows you the value that you enter
when configuring your DHCP server. In addition to the port number, the
“Circuit ID” also includes the ID of the VLAN that the DHCP relay received
the DHCP query from.
Note: The VLAN ID is located in the circuit ID's 4th and 5th octet. The
circuit ID displayed applies to untagged frames. If the DHCP relay
receives a VLAN-tagged frame, then the circuit ID that it sends to the
DHCP server can deviate from the one displayed.
Example of a configuration of your DHCP server:
Type: mac
Remote ID entry for DHCP server: 00 06 00 80 63 00 06 1E
Circuit ID: B3 06 00 00 01 00 01 01
