Introduced on the C-Series. Introduced on the E-Series. Usage Information You can add multiple DHCP servers by entering the ip helper-address command multiple times. If multiple servers are defined, an incoming request is sent simultaneously to all configured servers and the reply is forwarded to the DHCP client. Dell Networking OS uses standard DHCP ports, that is UDP ports 67 (server) and 68 (client) for DHCP relay services. It listens on port 67 and if it receives a broadcast, the software converts it to unicast, and forwards to it to the DHCP-server with source port=68 and destination port=67. The server replies with source port=67, destination port=67 and Dell Networking OS forwards to the client with source port=67, destination port=68. ip helper-address hop-count disable Disable the hop-count increment for the DHCP relay agent. Syntax ip helper-address hop-count disable IPv4 Routing 785
