AT-S7/AT-S9 Operations Manual

Received BPDUs will be submitted for transmission. They will also be
processed as required by the STP algorithm.
Disabled indicates a port that is NOT PARTICIPATING in frame relay. Nor
is it participating in the operation of the STP algorithm and protocol.
Received frames are discarded. Submitted frames are not forwarded for
transmission.
Disabled is left when the port is enabled by management action and the
blocking state is entered.
Polarity. The Polarity column shows the state of each UTP port’s receive
pair polarity: either Normal or Reversed.
Normal indicates correct polarity.
Reversed indicates incorrect polarity — software has detected that
your wiring has been installed with reversed polarity. It has also
subsequently corrected it. Operator intervention is not required.
Port Configuration To change port information, enter a port number from the Port Status menu.
The Port Configuration Menu appears. In this case, port #16 was selected.
The system and port name appear at the top of the screen. Below that is the
port’s status and configuration. And, below that, you see three menu options.
The following configuration options are available:
Enable/Disable. Selecting
Enable changes the port’s state to allow it to
transmit or receive data. Selecting Disable turns the port logically off, thus
preventing port traffic.
