A500: show signaling stats a1.2 qsaal screen
NOTE:
If there is no connection between the TN230X and the A500 at the Q.SAAL
protocol layer, no report appears.
— If
Port A1.2
(or the port of interest) is
not configured for
UNI signaling
, then the port was administered for no UNI
signaling (admin link command). Use the show signaling
summary command to verify that
Signaling
is
UNI3.1
.
— The
Supported only for UNI 3.0
line for the
SDP PDUs:
field means that the port was administered for UNI3.0 signaling
(admin link command). Use the show signaling summary
command to verify that
Signaling
is
UNI3.1
.
— The
POLL PDUs
and
STAT PDUs
counters should be increasing if
the TN230X is actively sending and receiving Q.SAAL Protocol Data
Units with the A500. This occurs even if the TN230X did not achieve
board insertion.
