Configuring for DHCP relay agent
To enable the Nortel Switched Firewall to be the DHCP forwarder, you need to configure the
DHCP server IP addresses on the firewall. You must enable DHCP relay on the interface
connected to the client subnet.
Figure 52
shows a basic DHCP network example:
Figure 52
DHCP relay agent configuration
The client request is forwarded to all DHCP servers configured on the firewall. The use of two
servers provides failover redundancy, but you can configure up to eight DHCP servers.
However, no health checking is supported.
DHCP Relay functionality is assigned on a per-interface basis. At least one server and one
interface must be enabled for DHCP, otherwise the configuration fails validation. Use the
following commands to configure the Nortel Switched Firewall as a DHCP relay agent:
1.
Enable DHCP Relay globally.
2.
Configure DHCP requests to enter on this interface.
