50 Express L768/L1.5 User Manual 61202192L1-1
When more than one DLCI mapping is listed, the Express L768/L1.5 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/L1.5 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 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 Map-
ping is saved. Items may be deleted when DEL appears below the status bar.
DLCI Mapping/Active
Write security: 3, Read security: 5
When this parameter is set to
Yes (def), the mapping is used to determine the
protocols used. If set to No , the Express L768/L1.5 will ignore the virtual cir-
cuit with this DLCI.
DLCI Mapping/DLCI
Write security: 3, Read security: 5
This is the DLCI associated with this virtual circuit. This value can range from
16 to 1007.
DLCI Mapping/IP Map
Write security: 3, Read security: 5
This menu represents the IP protocol mapping that is to take place for this DL-
CI.
IP Map/Active
Write security: 3, Read security: 5
When this is set to
Yes (def), the Express L768/L1.5 will attempt to transport
IP packets for this DLCI. A setting of No means that no IP traffic or route will
be exchanged.
