IP Routing Features

UDP Broadcast Forwarding

Configuring and Enabling UDP Broadcast Forwarding

To configure and enable UDP broadcast forwarding on the switch:

1.Enable routing.

2.Globally enable UDP broadcast forwarding.

3.On a per-VLAN basis, configure a forwarding address and UDP port type for each type of incoming UDP broadcast you want routed to other VLANs.

Globally Enabling UDP Broadcast Forwarding

Syntax [no] ip udp-bcast-forward

Enables or disables UDP broadcast forwarding on the routing switch. Routing must be enabled before executing this command. Using the no form of this command disables any ip forward protocol udp commands configured in VLANs on the switch. (Default: Disabled)

Configuring UDP Broadcast Forwarding on Individual VLANs

This command routes an inbound UDP broadcast packet received from a client on the VLAN to the unicast or broadcast address configured for the UDP port type.

Syntax [no] ip forward-protocol udp < ip-address> < port-number port-name>

Used in a VLAN context to configure or remove a server or broadcast address and its associated UDP port number. You can configure a maximum of 16 forward-protocol udp assign­ ments in a given VLAN. The switch allows a total of 256 forward-protocol udp assignments across all VLANs. You can configure UDP broadcast forwarding addresses regardless of whether UDP broadcast forwarding is globally enabled on the switch. However, the feature does not operate unless globally enabled.
