The 7210 SAS provides DHCP relay agent services for DHCP clients.
Service providers use the DHCP protocol to assign IP addresses and provide other configuration parameters. The DHCP protocol requires the client to transmit a request packet with a destination broadcast address of 255.255.255.255, which is processed by the DHCP server.
When the 7210 SAS is acting as a DHCP relay agent, it processes DHCP broadcast packets and relays them to a preconfigured DHCP server, ensuring that DHCP clients and servers do not need to reside on the same network segment.
DHCP offer messages are not dropped if they contain a giaddr that does not match the local configured subnets on the DHCP relay interface.
