Monitoring Device Performance 2-9

Using the TSX-1620 Hub View
Monitoring Device Performance
The information displayed in the Hub View can give you a quick summary of
device activity, status, and configuration. SPMA can also provide further details
about hub performance via its four-level menu structure. The Device, Module,
Interface/Bridge and Bridge Port menus give you control over the device at four
levels for both the Interface and Bridge application displays and give you access
to the tools, menus, and windows that let you monitor specific aspects of device
performance, change display options, and set TSX-1620 operating and notification
parameters. See Figure 2-5 and Figure 2-6 to view the different menus and their
contents.

Port Display Form

You can change the type of information displayed for each port by using the Port
Display Form option on the Interface or Bridge menus. Remember that you need
to change the application display to the proper mode to access the desired menu
(see The TSX-1620 Application Displays for details).
To change the port display form:
1. Click in the appropriate area to display the Interface or Bridge menu (refer to
Figure 2-3 on page 2-5).
2. Drag down to Port Display Form, then right as necessary to select one of the
port display options. The current selection will be displayed in the Port Display
Form text box, just above the ports.
Interface Port Display Form Options
Oper Status
The Oper Status port display form displays the current status of the port — ON,
OFF, NLK (no link), Test, or --- (unknown). Oper Status is determined by a
combination of MIB-II interface operational status (ifOperStatus), administrative
status (ifAdminStatus), and the interface’s physical link status (if applicable).
• The ON status indicates that the interface’s operational status is determined as
“UP”, that it has been administratively enabled, and that a physical link has
been detected at the port. A status of ON indicates that the port can send and
receive NMS packets, but does not indicate whether the port’s bridging
functions are enabled.
NOTE
To determine whether a port’s bridging functions are enabled, change the application
display mode to Bridge, and then select the Admin port display form. For more
information, see the definition of the Admin port display form, below.
