DHCP Relay

DHCP messages between DHCP clients and DHCP servers that are located in different IP
subnets.

DHCP Relay Configuration
To configure the DHCP Relay information:
1. Use Maximum Hop Count to enter the maximum number of hops a client request can
take before being discarded. The range is (1 to 16). The default value is 4.
2. Use Admin Mode to select enable or disable radio button. When you select 'enable' DHCP
requests will be forwarded to the IP address you entered in the 'Server Address' field.
3. Use Minimum Wait Time to enter a Minimum Wait Time in seconds. This value will be
compared to the time stamp in the client's request packets, which should represent the time
since the client was powered up. Packets will only be forwarded when the time stamp
exceeds the minimum wait time. The range is (0 to 100).
4. Use Circuit ID Option Mode to enable or disable Circuit ID Option mode. If you select
'enable' Relay Agent options will be added to requests before they are forwarded to the
server and removed from replies before they are forwarded to clients.
