2Enter the following commands:
configure terminal <enter>
interface [source interface] <enter>
ip helper-address [destination listener] <enter> (repeat this
command for each appliance you want to send to)
exit <enter>
ip forward protocol udp 1738 <enter>
end <enter>
Note: Any interface can have multiple helper-addresses.
Note: The “ip forward protocol upd” command specifies the ports to forward. In
this case, we recommend port 1738. You will need to list other ports if you
have configured other listener ports in Administration > System
Preferences > Listener communication.
3Exit the configuration interface.
Check Committed Information Rate values
If your network uses Frame Relay, check your Committed Information Rate (CIR)
values for your connectivity devices. Make sure you set the CIR on these
connections, so the correct statistics will be calculated.
In Frame Relay networks, a CIR is a bandwidth (expressed in bits per second)
associated with a logical connection in a permanent virtual circuit (PVC).
The CIR values for these devices are available from your service provider. Check
the appropriate documentation to obtain these values.
If the network activity on any particular PVC goes over normal operating
thresholds, you should be aware that the Frame Relay controller may mark some
packets to be deleted.
