Port Monitoring
Port Monitoring provides two levels of diagnostic tests:
- All Ports Display.
- Single Port Display.
All Ports Display provides diagnostic information about all the ports
simultaneously on a selected panel or server.
Single Port Display displays more detailed information on a selected
single port on a panel or server. The State and Device options
provide device information, communication parameters, throughput statistics
and status information for individual port devices. The Admin
option provides device manipulation functions, such as Flush, Reset,
Enable and Disable, while Tips and Report assist with reporting faults.
Access to All Port Display
To access the All Ports Display:
Step 1.
Highlight Analyze on the Panel Configuration Menu & press <Enter>.
Step 2.
Highlight Monitor and press <Enter>. The screen displays the All
Ports Display. This display provides useful diagnostic information
about all the ports on the selected panel or server.
Step 3.
Use the down arrow to scroll through the display.
Step 4.
To access the Single Port Display for a particular port, highlight
the port for further investigation and press <Enter>.
Step 5.
Activate any of the Single Port Display options if necessary.
See explanations of individual options, in this Section, for a description
of each available option.
Step 6.
<ESC> returns you to the All Ports Display.
Access to Single Port
Display
The Single Port Display can be accessed through the All Ports Display
as outlined above, or by selecting Analyze from the Port Configuration
Menu:
Step 1.
Highlight Select on the Panel Configuration Menu and press <Enter>.
Step 2.
Highlight the port to analyze and press <Enter>.
Step 3.
Highlight Analyze on the Port Configuration Menu and press <Enter>.
Step 4.
Highlight Monitor and press <Enter>.
The Single Port Display for the selected port is shown on the screen
displaying:
- Port Configuration Parameters.
- Percentage Throughput.
- Status of RS232 Signals.
Port Status
You can use the next level of diagnostics to further examine the port
setup. The options available for reporting and device manipulation
are: State, Device, Admin, Report, Tips
Single Port
Display Field Descriptions
Device Type identifies which of the port's devices is currently being
displayed.
Device identifies the device file in the /dev directory which corresponds
to the displayed device. For example, tty1a00 for /dev/tty1a00.
Comms summarizes the port's communications setup. This comprises
five communication parameters, each beginning with a word describing
the parameter, followed by the parameter's value as configured through
easyadm:
- Baud - the port's baud rate setting (bits/second).
- Data - the port's number of data bits per char setting.
- Stop - the port's number of stop bits per character.
- Par - the port's parity setting.
- Hndshk - the port's handshaking setting.
These parameters are identical for all of the port's devices.
Description describes the various attributes of the current device
(eg. terminal types, printer names, etc.).
Percentage Throughput shows receive and transmit throughput as a percentage
of the port's capacity at its Baud Rate.
Total Chars the total number of characters, including flow control
characters, exchanged on the current device.
Status displays the current device's line status and whether the device
is Open (Operating) or Closed (Not currently operating).
State
You can use the State option on the Single Port Display to acquire
detailed technical port information for the selected device. This
display records statistics on character exchange, hardware and software
flow control and error conditions:
Step 1.
Highlight State and press <Enter>.
Step 2.
The Technical Port Display for the selected port shows on the screen.
The information relates to Software and Hardware Flow Control and
character transmission data. See Technical
Port Display Field Descriptions in Part 2 for field specific information.
Step 3.
Press <Enter> at the Detail option if you need to toggle between
the two statistics screens.
Note: The Host State/Slave State statistics screen is offered
as diagnostic information for Stallion support use. The user is not
required to interpret the data displayed.
Step 4.
Press <Enter> at the View option if you wish to display more
advanced technical information.
View is accessed through State on the Single Port Display:
Step 1.
With the Technical Port Display on the screen, press <Enter>
to activate the View option.
Step 2.
Port State information displays:
- EasyConnection Port State.
- Port Control Flags.
- Port Input Flags.
- Port Output Flags.
