1.1.9 Automatic Configuration At Power-Up
The TRMM-2 stores operational parameters in its Non-Volatile RAM
(NVRAM). Whenever the TRMM-2 is powered-up or reset, it compares
the MIMs currently in the hub with those last registered. All MIMs
recognized throughout the hub are placed in management mode and
reconfigured according to settings stored in the NVRAM. Thus,
configuration settings stored before power-down are reinstated at the next
power-up.
Any MIM that is not recognized at power-up is allowed to operate in the
configuration dictated by its own hardware settings. The TRMM-2
observes the MIM’s configuration and stores them in NVRAM.
1.1.10 RMON Functionality
The TRMM-2 performs RMON (Remote Monitoring MIB) statistical
monitoring on all interfaced LANs. See Appendix E, for a listing of
supported MIBs. Using the STATION port interface to make the
connection, the TRMM-2 can perform RMON monitoring on any Token
Ring network within a cable’s reach.
1.1.11 SNMP Traps
The TRMM-2 operates as a Ring Error Monitor (REM), collecting data
on the network, monitoring performance conditions, and noting station
access to the Token Rings. Using the Local Management application, you
may configure the TRMM-2 to issue SNMP traps to selected network
management stations to provide information about the network.
1.1.12 Ring Security
Ring Security is a feature that enables network managers to monitor and
restrict station access to Token Rings through an editable “allowed list”
which registers the MAC address of each station “allowed” on the ring.
See the TRMM-2 Local Management User’s Guide for details and
procedures.
