●TD(2), etc. – The signal names (with connector pin numbers in parentheses) are
listed as ON, OFF, or UNK (unknown: non-functional, unused, or in transition
between states). For different physical interfaces, the names remain the same,
but the numbers change.

Monitoring Traffic

Serial Po rts

The port monitor displays the con trol data and information data of traffic passing over
a serial interface. Data can be gathere d in real time for an X.25, SDLC , BSC, or async
port, or an LLC2 session.

Running the traffic monitor on a frame relay port will degrade

performance on the port.

Press [A] at the Traffic Monitor Menu (or [C], [E], [A] from t he Main Me nu) and, wh en
prompted, enter a Port number: 0–7 for physical ports, 8–63 for log ica l ports , or 65 to
monitor LLC2 sessions. Valid numbers for physical ports depend on the model of
SmartSwitch 1800—see port locations on page 6-1.
While remotely controlling a node, you cannot monitor the line to which
you are connected.
A message like the following will appear:
