Configuring IP parameters – Layer 2 Switches

NOTE

When DHCP Assist is enabled on any port, Layer 2 broadcast packets are forwarded by the CPU.
Unknown unicast and multicast packets are still forwarded in hardware, although selective packets
such as IGMP are sent to the CPU for analysis. When DHCP Assist is not enabled, Layer 2 broadcast
packets are forwarded in hardware.

Configuring DHCP Assist

You can associate a gateway list with a port. You must configure a gateway list when DHCP Assist is
enabled on a Layer 2 Switch. The gateway list contains a gateway address for each subnet that will
be requesting addresses from a DHCP server. The list allows the stamping process to occur. Each
gateway address defined on the Layer 2 Switch corresponds to an IP address of the router interface
or other routers involved.
