Configuring Frame Relay Services
3-2 117376-B Rev. 00
Selecting a Management Type
You can specify the management protocol that the router and the frame relay
network use to communicate status information. Routers connected back to back
also use a management protocol to exchange status information. The following list
describes your options:
• DLCMI None provides no management interface between the router and the
frame relay network. In the absence of management support, you must
configure all PVCs manually.
• Rev 1 LMI provides user-side management services as specified by Revision 1
of the Local Management Interface standard.
• ANSI T1.617D provides user-side management services as specified in Annex
D to ANSI standard T1.617-1991. This is the default value.
• CCITT Annex A provides user-side management services as specified by the
ITU-T (formerly CCITT).
• LMI Switch offers limited management services for the DCE side of the
connection as specified by Revision 1 of the Local Management Interface
standard.
• Annex D Switch provides limited management services for the DCE side of
the connection as specified in Annex D to ANSI standard T1.617-1991.
• Annex A Switch provides limited management services for the DCE side of
the connection as specified by the ITU-T.
If you are connecting two routers back to back, use one of the DTE parameter
options (Rev 1 LMI, ANSI T1.617D, CCITT Annex A) for the router acting as a
DTE, and one of the DCE options (LMI Switch, Annex D Switch, Annex A
Switch) for the router acting as the DCE. Although you can configure the router
for the DCE side of a connection, the router cannot act as a full switch, and it will
not perform complete bidirectional signaling.
The LMI Switch, Annex D Switch, and Annex A Switch options are primarily for
troubleshooting.
