active. These active DLCIs will attempt to determine the IP and IPX
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 unnumbered
interface. Bridge connections are made using bridge group 1.
When more than one DLCI mapping is listed, the Express 6100/6120
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 6100/6120 falls back to using IARP (as dis-
cussed 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.
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 6100/6120 will ig-
nore 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.
