Managing Faults on Avaya Virtual Services Platform 7200 Series and 8000 Series Version 4.2.1

Chapter 3: Fault management fundamentals
Fault management includes the tools and features available to monitor and manage faults. This
section provides overview for local alarms, remote monitoring (RMON), traps and logs, and link
stage changes (port flapping).
Local alarms
The switch contains a local alarms mechanism. Local alarms are raised and cleared by applications
running on the switch. Active alarms are viewed using the show alarm database command in
ACLI. Local alarms are an automatic mechanism run by the system that do not require any
additional user configuration. Check local alarms occasionally to ensure no alarms require additional
operator attention. The raising and clearing of local alarms also creates a log entry for each event.
Remote Monitoring (RMON)
This section provides information on Remote Monitoring (RMON1) and RMON2.
Remote Monitoring
Remote Monitoring (RMON) is a management information base (MIB) or a group of management
objects that you use to obtain or configure values using the Simple Network Management Protocol
(SNMP). Use ACLI, or EDM, to globally enable RMON on the system. After you globally enable
RMON, you enable monitoring for individual devices on a port-by-port basis.
RMON1 is the original version of the protocol, which collects information for OSI Layer 1 and Layer
2 in Ethernet networks. RMON1 provides traffic statistics at the MAC layer, and provides statistics
on Ethernet segments for packets and bytes received and transmitted.
You can use RMON1 to:
• Configure alarms for user-defined events.
• Collect Ethernet statistics.
• Log events.
• Send traps for events.
