Defining DHCP Relay Properties
The Properties page enables configuring the DHCP Relay status on the switch, and the IP addresses of the DHCP server where the DHCP messages are relayed.
To use this feature, it is necessary to activate the DHCP Relay on the ingress interface where the DHCP messages are to be relayed. This can be done in the DHCP Relay Interfaces page.
Option 82 inserts additional information to the packets sent from the host. The DHCP server passes the configuration information to hosts on a TCP/IP network. This permits the DHCP server to limit the address allocation to authorized hosts. DHCP with Option 82 can only be enabled if DHCP Relay is enabled.
To configure the DHCP Relay feature:
- Click IP Configuration > DHCP Relay (Layer 2 or Layer 3) > Properties. The Properties page opens.
- Enter values for the following fields:
- Click Add to enter the IP address of the DHCP server. The Add DHCP Properties page opens.
- Enter the value for the following field:
- Click Apply. The DHCP server is defined, and the Running Configuration file is updated.
Use the DHCP Relay Interfaces page to configure the interfaces that support DHCP Relay.
