ProSAFE M7100 Managed Switches
RMON Stats and History Commands
The various MIBs within RFC 2819, 3273, and 3434 are arranged into groups. The managed
switch supports some of the groups in these RFCs but not all. The managed switch complies with
MODULE-COMPLIANCE and OBJECT-GROUP definitions within these RFCs for supporting
individual groups.
The managed switch supports the following groups:
RFC 2819
• Group 1 - Statistics
Contains cumulative traffic and error statistics.
• Group 2 - History
Gener
ates reports from periodic traffic sampling that are useful for analyzing trends. This
group includes His
tory Control Group and Ethernet History Group.
• Group 3 - Alarm
Enables the definition and setting of thresholds for various counters. Thresholds can be
passed in either a rising or f
alling direction on existing MIB objects, primarily those in the
Statistics group. An alarm is triggered when a threshold is crossed and the alarm is passed to
the Event group. The Alarm requires the Event Group.
• Group 9 - Event
C
ontrols the actions that are taken when an event occurs. RMON events occur when:
• A threshold (alarm) is exceeded
• There is a match on certain filters.
RFC 3273
• Group 1 - Media Independent Group
Contains media-independent statistics that provide information for full and/or half-duplex
links as w
ell as high capacity links.
• Group 2 - Ether Stats High Capacity Group
Contains the High Capacity RMON extensions to RMON-1 etherStatsTable (RFC 2819
Group 1).
• Group 3 - Ether History High Capacity Group
C
ontains the High Capacity RMON extensions to RMON-1 etherHistoryTable (RFC 2819
Group 2).
