1.1.10 RMON Functionality
The TRMM-4 performs RMON (Remote Monitoring MIB) statistical
monitoring on all interfaced LANs. See Appendix D, for a listing of
supported MIBs.
1.1.11 SNMP Traps
The TRMM-4 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
can configure the TRMM-4 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-4 Local Management User’s Guide for details and
procedures.
1.1.13 Automatic Beacon Recovery Process (ABRP)
The TRMM-4’s Automatic Beacon Recovery Process (ABRP) actively
guards against network interruptions due to beaconing. When beaconing
is detected, ABRP isolates the problematic portion of the network from
the ring, enabling the network to recover without user intervention and
preventing beaconing conditions from halting network operations. See
Appendix B for more information on ABRP and the network problems it
addresses.
1.1.14 Access To MIB Libraries
Among the tools provided by the TRMM-4 Local Management is a MIB
Navigator. This tool allows you to browse through and access the library
of MIBs (Management Information Bases) available with the TRMM-4.
A list of supported MIB groups is provided in Appendix D. See the
TRMM-4 Local Management User’s Guide for further detail on the use
of the MIB Navigator tool.
