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.
