Using the 7C0x SmartSwitch Hub View

Monitoring Hub Performance

Displays each port’s logical index number, which reflects the port’s logical 
position in relation to the SMT entity to which it is assigned. (Each FDDI interface 
has its own SMT entity; these are indexed from left to right in the hub, and from 
top to bottom on each module.) Note that the assigned logical index numbers do 
not necessarily reflect each port’s physical position on the module or in the hub; 
for example, an interface whose physical index is 20002 might have individual A 
and B logical indices of 1.1 and 1.2, indicating that the A and B ports which 
together form the interface are ports number 1 and 2 assigned to SMT number 1.

For all FDDI port display forms, the color coding is the same: 

•

 indicates that the port is active; this is, the port has been enabled by 

management, has a valid Link signal, and is able to communicate with the 
station at the other end of the port’s cable segment.

•

 indicates that the port has been disabled through management, or that it 

is in a standby state.

•

 indicates that the port is enabled but does not currently have a valid 

connection. This usually indicates that the device at the other end of the 
segment is turned off, or that no cable segment is attached.

•

 indicates that port is administratively enabled, but not operational due to 

some hardware or network problem.

The Switch Application Display — available only for devices which have been 
configured (via Local Management) to operate as SecureFast switches — allows 
you to view each switch interface according to switching status and statistics; it 
also provides access to the Switch menu (

), from which you can launch 

a Switch Status window and change the port display form. This is the default 
display mode for devices configured for SecureFast operation.
