NOTE:
For a specific DLCI on a BRI interface, statistics are kept on one of the
B channels. To determine which B channel includes a particular DLCI, look at
the BRI-B1 and/or BRI-B2 interface’s LMI Reported DLCIs screen
(Path: main/status/dlcis/ [BRI-B1/BRI-B2]).
For total activity for a DLCI over the backup channels, check the DLCI’s
statistics on both BRI interfaces. Multiple backups of the DLCI may have
occurred, and backup may not have occurred over the same BRI interface
each time.
