APPENDIX B
STATION PORT INTERFACE
The STATION port interface of the TRMM-2 can be used to:
• Monitor network activity on a second Token Ring within the host
MMAC
• Monitor conditions on a Token Ring outside the host MMAC
•
Provide side-band management of the LAN monitored by the FNB
interface (see
Section B.3 )
B.1 CONNECTIONS WITHIN THE HOST MMAC
The TRMM-2 can control all Token Ring MIMs within the host MMAC.
For instance, it can assign ports to different rings, enable or disable ports,
or configure ports for RO use, even if the STATION port interface is not
attached. FNB Ring 1 is always fully managed; however, the STATION
port interface must be connected for the TRMM-2 to monitor a second
Token Ring.
You must use the Local Management application to designate the location
of the STATION port interface or the TRMM-2 will not:
• Report the Active Monitor of the ring.
•
Provide ABRP.
•
Report the ring status (it is listed as
Closed
).
NOTE
The STATION port interface should not be connected where it
will duplicate the TRMM-2’s fixed connection to FNB Ring 1. In
this case, the TRMM-2 would track network activity on both
interfaces as if they were connected to separate networks,
possibly causing administrative conflicts if the TRMM-2 was to
exercise two different management control policies over the
same ring.
