Cisco ONS 15454 Installation and Operations Guide, R3.2
March 2002
Chapter 11 SNMP
SNMP Remote Network Monitoring
ONS 15454 RMON implementation is based on the IETF-standard MIB Request for Comment
(RFC)1757. The ONS 15454 implements five groups from the standard MIB: Ethernet Statistics, History
Control, Ethernet History, Alarm, and Event.
11.7.1 Ethernet Statistics Group
The Ethernet Statistics group contains the basic statistics for each monitored subnetwork in a single table
named etherstats.
11.7.2 History Control Group
The History Control group defines sampling functions for one or more monitor interfaces. RFC 1757
defines the historyControlTable.
11.7.3 Ethernet History Group
The ONS 15454 implements the etherHistoryTable as defined in RFC 1757, within the bounds of the
historyControlTable.
11.7.4 Alarm Group
The Alarm group consists of a single alarm table. This table provides the network performance alarm
thresholds for the network management application. With CTC, you can provision the thresholds in the
table.
11.7.5 Event Group
The Event group consists of two tables, eventTable and logTable. The eventTable is read-only. The ONS
15454 implements the logTable as specified in RFC 1757.
