Use the following procedure to assign a UDP forwarding list to a VLAN and to configure the related UDP forwarding parameters for the VLAN.
Enable IP routing globally.
Enable IP routing and configure an IP address on the target VLAN interface.
Ensure that a route to the destination address is available on the switch.
From the navigation pane, double-click IP.
In the IP tree, click UDP Forwarding.
In the UDP Forwarding work area, click the Broadcast Interfaces tab.
On the toolbar, click Insert.
Click the LocalIfAddr ellipsis ( ... ) to select a VLAN IP address from the list.
Click the UdpPortFwdListId ellipsis ( ... ) to select the desired UDP forwarding list to apply to the VLAN from those listed.
Type the maximum TTL value in the MaxTtl field.
Type the broadcast mask in the BroadCastMask field.
Click Insert.
On the toolbar, you can click Refresh to verify the UDP forwarding list to VLAN configuration.
The following table describes the fields of the Broadcast Interface tab.
Field | Description |
---|---|
LocalIfAddr | Indicates the IP address of the local VLAN interface. |
UdpPortFwdListId | Indicates the port forwarding lists associated with the interface. This ID is defined in the Forwarding Lists tab. |
MaxTtl | Indicates the maximum number of hops an IP broadcast packet can take from the source device to the destination device. This is an integer value between 1 and 16. |
NumRxPkts | Indicates the total number of UDP broadcast packets received by this local interface. |
NumFwdPkts | Indicates the total number of UDP broadcast packets forwarded. |
NumDropPktsDestUnreach | Indicates the total number of UDP broadcast packets dropped because the destination was unreachable. |
NumDropPktsUnknownPort | Indicates the total number of UDP broadcast packets dropped because the destination port or protocol specified has no matching forwarding policy. |
BroadCastMask | Specifies the 32 bit mask used by the selected VLAN interface to take forwarding decisions based on the destination IP address of the incoming UDP broadcast traffic. If you do not specify a broadcast mask value, the mask of the interface to which the list is attached is used. |
