These active DLCIs will attempt to determine the IP and IPX address-
es 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 ta-
bles and the virtual circuit will be treated as an unnumbered interface.
Bridge connections are made using bridge group 1.
When more than one DLCI mapping is listed, the Express L768 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 L768 falls back to using IARP (as discussed in the
previous paragraph) to determine the protocols to use with that par-
ticular virtual circuit. If a static maintenance protocol is used, at least
one DLCI mapping must be specified.
DLCI Mapping/Active
Write security: 3, Read security: 5
When this parameter is set to Yes (def), the mapping is used to deter-
mine the protocols used. If set to No , the Express L768 will ignore the
virtual circuit with 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.
