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.

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. - Continued on the next page. - 3-66

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 i
n 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.
