Specify values for the following parameters:
Port Monitoring
Used to Enable or Disable the port monitoring function. The default is
Disable.
Monitoring Port
This is the slot.port that the monitored data is sent to. This is the slot.port
that a Network Analyzer is attached to. The slot can be 0, 1 or 2. The
default is 0. The port range is 1 to 16 for Slot 0; 1 to 2, 1 to 4, or 1 to 8 for
Slots 1 and 2.
When Port Monitoring is Enabled, make sure that the monitoring port is
connected to a network analyzer and not to the network itself to avoid
potential problems.
Port to be Monitored
This is the port from which data is captured and sent to the monitoring port
(the port under analysis). The port range is 1 to 16 for Slot 0; 1 to 2, 1 to 4,
or 1 to 8 for Slots 1 and 2.
