Frame Relay DLCI
The Frame Relay DLCI dialog box initially displays one DLCI in the total DLCI’s window. This DLCI is
provided as an example of a DLCI and has not been mapped to any protocol or logical WAN.
To add a new DLCI Number, enter the number in the DLCI window (e.g., 200). You do not have to enter
the leading zeros. When you click the Add button, the new DLCI appears in the Configured DLCI’s
window. When you highlight the new DLCI, the default Committed Information Rate, Excess Burst rate
of “0”, and Mode setting of “Adhere to CIR” will be displayed.
You can now map the new DLCI to a protocol stack and frame relay parameters (i.e., CIR, Be, and
Mode). To map a DLCI to a protocol stack, highlight the DLCI number in the Configured DLCI window.
The Protocol Stacks Mapped group becomes active. Click on the protocol stack you wish to map the
DLCI to and then click the down arrow for that protocol: address/network numbers for the protocol are
displayed. Select the address/network number/STP WAN number you wish to map to the new DLCI.
The protocol number that appears was established when you configured your logical WAN(s) for the
selected protocol.
The frame relay parameters in the Settings (in Bits/second) and Mode groups have to coincide with
how the frame relay access is provisioned. You will probably have to delete the default values and
reenter your provisioned values that were provided by your T1 service provider.
The Mode settings are used to avoid possible loss of data. Mode settings determine how the
RouteFinder handles congestion. The Mode group selects whether the RouteFinder should use its own
throughput calculations to avoid congestion, or simply send data to the network As Fast as Possible.
The RouteFinder calculates throughput after every CIR Measurement Interval, and can limit throughput
to either the CIR (Adhere to CIR) or the CIR plus the Be (Adhere to CIR+Be).
The following Frame Relay DLCI dialog box illustrates DLCI 100 with all the protocol stacks enabled,
their respective network numbers, and the default CIR, BE and Mode settings. You would map your
DLCIs to your network protocols and set your CIR, Be, and Mode according to how your service
provider set up your T1 service.
Once all DLCI’s have been mapped, click Save and then click the Download Setup button on the
Router Setup main menu to write the new DLCI configurations to the MTASR2-203 RouteFinder.
