2. Ensure that the fields have the following indicated values.
Receive
Cell Count
Each field’s values should be increasing if the TN230X is
actively sending and receiving cells with the A500. (Even if
a TN230X did not achieve board insertion, it will still try to
talk to the A500.)
Transmit
Cell Count
If neither field is increasing, the A500 port may have been
marked down using the admin down command. Use the
show system interfaces command to verify that the
Admin Status is up.
If the
Receive Cell Count
is increasing but the
Transmit Cell Count is not increasing, this may be
because the port was administered with no UNI signaling
(admin link command). Use the show signaling summary
command to ensure that
Signaling
is
UNI3.1
.
The error counters may not be zero, but should not be large
either compared to the receive and transmit cell counters. If
the counters are large and increasing, check the fiber
integrity. Make sure the fiber pairs are securely plugged into
both the TN230X and the A500.
If the fiber has been pulled and reinserted as part of fault
diagnosis, the non-zero
Loss of Signal Err counter
may be correct.
