The 7210 SAS provides DHCP/BOOTP Relay agent services for DHCP clients. DHCP is used for IPv4 network addresses. DHCP is known as stateful protocols because they use dedicated servers to maintain parameter information. In the stateful auto-configuration model, hosts obtain interface addresses and configuration information and parameters from a server. The server maintains a database that keeps track of which addresses have been assigned to which hosts.
DHCP relay on different 7210 SAS platforms is as follows:
7210 SAS-D, 7210 SAS-Dxp, and 7210 SAS-K 2F1C2T support DHCP Relay on the base router, and on access IP interfaces associated with IES service used for management.
7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C support DHCP Relay on the base router, and on access IP interfaces associated with IES service and VPRN service.
