FIGURE 12 DHCP oers are forwarded back toward the requestors
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.
Conguring DHCP Assist
You can associate a gateway list with a port. You must congure a gateway list when DHCP Assist is enabled on a Brocade 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 dened on the Layer 2 switch corresponds to an IP address of the Brocade
router interface or other router involved.
