(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 unnumbered
interface. Bridge mode is not attemped in this case.
When more than one DLCI mapping is listed, the Express 4100/4110 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
Express 4100/4110 falls back to using IARP as 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.
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 param-
eters 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 sta-
tus bar.

When this parameter is set to Yes (def), the mapping is used to determine
the protocols used. If set to No, the Express 4100/4110 will ignore the vir-
tual circuit with this DLCI.

This is the DLCI associated with this virtual circuit. This value can range
from 16 to 1007.
