Chapter6 Edit Interface/Connection
Connection: Serial Interface, Frame Relay Encapsulation
DLCI
Enter the data link connection identifier (DLCI) in this field. This number must
be unique among all DLCIs used on this interface. The DLCI provi des a unique
Frame Relay identifier for this connection.
If you are editing an existing connection, the D LCI field will be disabled. If you
need to change the DLCI, delete the connection and create it again.
LMI Type
Ask your service provider which of the following Local Mana gement Interface
(LMI) types you should use. The LMI type specifies the protocol used to monitor
the connection:
ANSI
Annex D defined by American National Standards Institute (ANSI) standard
T1.617.
Cisco
LMI type defined jointly by Cisco and three other companies.
ITU-T Q.933
ITU-T Q.933 Annex A.
Autosense
Default. This setting allows the router to detect which LMI type is used by the
switch and then use that type. If autosense fails, the router will use the Cisco LMI
type.
Use IETF Frame Relay Encapsulation
Check this check box to use Internet Engineering Task Force (IETF)
encapsulation. This option is used to connect with routers not from Cisco. Check
this box if you are connecting to a router not from Cisco o n this interface.
