Using the TRMMIM Hub View

Managing the Hub

The number of frames addressed to the selected station that have the A bits 
already set to 1, which indicates a possible electrical line disturbance, or a 
duplicate address on the ring.

The number of times the selected station, while acting as the active monitor, has 
detected an error that required the transmission of a token.

The number of times the selected station has detected that the incoming signal’s 
frequency differed from the expected frequency by more than allowed.

In addition to the performance information described in the preceding sections, 
the Hub View also provides you with the tools you need to configure your hub 
and keep it operating properly. Hub management functions at the device level 
include finding a MAC address and setting the polling intervals to contact the 
device. At the module level, you can configure the module’s FNB left and right 
connections, set board speed and operating mode, and enable all ports on the 
module. At the station or ring port levels, you can remove a station from the ring, 
convert a station port to a ring-out port; and enable or disable station or ring 
ports. 

From the Device menu, you can select the Find MAC Address and Polling 
Intervals menu options.

The Find MAC Address menu command will let you search for any station on the 
TRMMIM-controlled ring by MAC address. When a station is found, its location 
will be described by module and port number.

To start the Find MAC Address command:

1.

Drag down to Find MAC Address, and release. The following window will 
appear.
