, etc. – The signal names (with connector pin numbers in parentheses) are
listed as
ON
,
OFF
, or
UNK

between states). For different physical interfaces, the names remain the same,
but the numbers change.
If displaying signal information for a remote subscriber, press

Monitoring Traffic
Serial Ports
The port monitor displays the control data and information data of traffic passing over
a serial interface. Data can be gathered 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 the Main Menu) and, when
prompted, enter a
Port
number:
0–7
for physical ports,
8–63
for logical 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.
