4.11.15 DHCP Relay 

A DHCP Relay agent is configured to listen for DHCP or BOOTP broadcast from DHCP clients and then relay those messages 

to DHCP servers on different subnets. 

 

 

Figure 4-11-15 

DHCP Relay 

 

The page includes the following fields: 

Object 

Description 

•

 

Mode 

Enables or Disables DHCP Relay function. 

•

 

Server IP 

Enteres remote DHCP server IP address. 

 

 

4.11.16 DHCP Option 82 

The DHCP option 82 enables a Dynamic Host Configuration Protocol (DHCP) relay agent to include information about itself 

when forwarding client-originated DHCP packets to a DHCP server. The DHCP server can use this information to implement IP 

address or other parameter-assignment policies.
