The default LMI profile contains the following hard-coded parameters:
For information about configuring the LMI Profile ID field, see “FRF.5 Attributes” on
page 10-66.
NNI DLCI — If you select an LMI profile, you must specify the NNI DLCI for the
network interworking PVC. This DLCI can differ from the DLCI configured at the
UNI port. The LMI that the NNI runs will use this DLCI to identify the PVC.
The NNI DLCI value should be a valid DLCI value (in the range of 16 - 991, and
1022).
For information about configuring the NNI DLCI field, see “FRF.5 Attributes” on
page 10-66.

LMI Protocol
Q.933 Annex A
Note – The parameters listed above are hard-coded for the LMI running on the NNI
(Network Interworking) PVC.
The LMIs at both FR UNI DCE endpoints, however, do not have to be set to Q.933
Annex A. They can be set to any of the following protocols: Disable, LMI Rev1,
ANSI T1.617 Annex D, CCITT Q.933 Annex A, or Auto Detect.
Note – Review the Restrictions and Special Considerations section of the Software
Release Notice for CBX Switch Software that comes with your release for specific
PVC capacities. The information about PVC capacities describes the use of NNI
DLCI with VPI/VCI values.
