Managing the broadcast interface

You can specify and display which router interfaces will receive UDP broadcasts to be forwarded.

To add a UDP broadcast interface:

  1. From the main menu, choose IP Routing > UDP Forwarding >Broadcast Interface.
    2. The UDP Forwarding dialog box opens with the Broadcast Interfaces tab displayed.
  2. Click Insert.
    3. The UDP_Forward, Insert Broadcast Interfaces dialog box opens.
  3. In the LocalIfAddr text box, type a local interface IP address; or click the Addr button to select an address from the list.
  4. In the UdpPortFwdListId text box, type the forwarding list ID; or choose an ID from the list.
  5. In the MaxTtl field, type the maximum number of hops an IP broadcast can take from the source device to the destination device (the default is 4; the range is 1 to 16).

The table below describes the items in the Broadcast Interface tab and Insert Broadcast Interface dialog box.


Item Description
LocalIfAddr
The IP address of the local router interface that will receive UDP broadcast packets that are forwarded.
UdpPortFwdListId
The number of the UDP lists/profiles that this interface is configured to forward (0 to100). A value of 0 indicates that the interface will not forward any UDP broadcast packets.
MaxTtl
The maximum number of hops an IP broadcast packet can take from the source device to the destination device (the default is 4; the range is 1 to 16).
NumRxPkts
The total number of UDP broadcast packets received by this local interface.
NumFwdPkts
The total number of UDP broadcast packets forwarded by this local interface.
NumDropPacketsTtlExpired
The total number of UDP broadcast packets dropped because the time to live (TTL) has expired.
NumDropPacketsDestUnreach
The total number of UDP broadcast packets dropped because the destination was unreachable.
NumDropPacketsUnknownPort
The total number of UDP broadcast packets dropped because the destination port/protocol specified has no matching forwarding policy.
