Total Access 600R User Interface Guide (UIG)
DLCI Mapping
This menu allows each DLCI to be mapped to a particular Frame Relay maintenance protocol. Each
protocol parameter can be individually configured for each DLCI. By factory default, the DLCI map is
empty.
When empty and a maintenance protocol other than static is used, the Total Access 600R will poll the
switch to determine which DLCIs are active. These active DLCIs will attempt to determine the IP
addresses on the other end of the virtual circuit using Inverse ARP (IARP). If there is a response, the
network learned will be added to the router tables and the virtual circuit will be treated as an unnum-
bered interface. Bridge connections are made using bridge group 1.
When more than one DLCI mapping is listed, the 600R will try to match the DLCIs learned from the
Frame Relay switch with the DLCI values in the map. If there is a match, the protocols specified in the
map are used. However, if an active DLCI is not in the list, it looks for an entry that has 0 in the DLCI
field. This entry is considered the default entry to use when no match occurs. If this default entry is not
present, the Total Access 600R falls back to using IARP (as discussed in the previous paragraph) to
determine the protocols to use with that particular virtual circuit. If a static maintenance protocol is
used, at least one DLCI mapping must be specified.
ACTIVE
When this parameter is set to Yes (def), the mapping is used to determine the protocols used. If set to
No, the Total Access 600R will ignore the virtual circuit with this DLCI.
DLCI
This is the DLCI associated with this virtual circuit. This value can range from 16 to 1007. Default is
0.
IP M
AP
This menu represents the IP protocol mapping that is to take place for this DLCI.
To insert a new profile, press the
I
key when over the Num column. A new inserted profile will
always be set up with the default parameters. To copy parameters from an old profile to this newly
inserted profile, use the copy (
C
) and paste (
P
) keys. Entire configuration trees can be copied with
this method.
To delete an unused profile, use the
D
key when the cursor is over the number in the Num column.
Once deleted, the profile is gone permanently as soon as the DLCI Mapping is saved. Items may be
deleted when DEL appears below the status bar.
A
CTIVE
When this is set to Yes (def), the Total Access 600R will
attempt to route IP packets for this DLCI. A setting of No
means that no IP traffic will be routed.
