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). Ifthereisaresponse,thenetworklearnedwillbeaddedtothe

router tables and the virtual circuit will be treatedas an unnumbered

interface. Bridge connections are made using bridge group 1.

When more than one DLCI mapping is listed, the Express 6100/6120

will trytomatch the DLCIslearned from the Frame Relay switchwith

theDLCIvaluesinthemap. Ifthereisamatch,theprotocolsspecified

in the map are used. However, if an active DLCI is not in the list, it

looksforanentrythathas0intheDLCI field.Thisentryisconsidered

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, Readsecurity: 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

key when over the Num

column. A new inserted profile will always be set upwith

the default parameters. To copy parameters from an old

profile to this newly inserted profile, use the copy (

)and

paste (

) keys. Entire configuration trees can be copied

with this method.

To delete an unusedprofile, usethe

key when the cursor

is over the number in the Num column. Oncedeleted, the

profileis gone permanently as soon as the DLCI Mapping

is saved. Items may be deleted when DEL appears below

the status bar.
