Configuring A Dhcp Gateway For The Relay - Alcatel OmniSwitch 6624 Network Configuration Manual

Configuring Authenticated VLANs
When this command is specified, the switch will act as a relay for authentication DHCP packets only; non-
authentication DHCP packets will not be relayed. For more information about using the ip helper avlan
only command, see Chapter 15, "Configuring DHCP Relay."

Configuring a DHCP Gateway for the Relay

The default authenticated VLAN DHCP gateway must also be configured through the
dhcp command so that Telnet and Web browser clients can obtain IP addresses prior to authentication.
This gateway is a router port in any of the authenticated VLANs in the network. It specifies the scope into
which an authentication client receives an initial IP address. For example:
-> aaa avlan default dhcp 192.10.10.22
Telnet and Web browser clients will initially receive an IP address in this scope. (After authentication,
these clients may require a new IP address if they do not belong to the VLAN associated with this gate-
way address.)
To remove a gateway address from the configuration, use the no form of the aaa avlan default dhcp
command. For example:
-> no aaa avlan default dhcp
