Cabletron Systems TSX-1620 Manuel D’Utilisation

Monitoring Device Performance

2-9

Using the TSX-1620 Hub View

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 

 to view the different menus and their 

contents.

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 

To change the port display form:

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.

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.
