Operating Notes for UDP Broadcast Forwarding

Maximum Number of Entries. The number of UDP broadcast entries and
IP helper addresses combined can be up to 16 per VLAN, with an overall
maximum of 256 on the switch. (IP helper addresses are used with the switch's
DHCP Relay operation. For more information, refer to "Configuring DHCP
Relay" on page 11-73.) For example, if VLAN 1 has 2 IP helper addresses
configured, you can add up to 14 UDP forwarding entries in the same VLAN.
