Configuring RMON

The RMON configuration contains two parts: RMON statistics and RMON alarm.

Configuring RMON Statistics

RMON statistics contains RMON ethernet statistics and history statistics:

RMON Ethernet statistics monitors traffic with continuous statistics on the Ethernet interface. It counts the number of broadcast and multicast messages, the number of network conflicts, the number of CRC checksum error messages, the number of undersized (or oversized) data messages, the number of dropped messages, and the number of received packets in bytes.
Configure RMON historical statistics function when you want to periodically collect data on a specified interface. It gathers statistics for the bandwidth utilization, the number of error packets, the total number of packets, etc.

Configuring RMON Ethernet Statistics

Step1 Configure RMON ethernet statistics on a specified interface.

set protocols snmp rmon statistics <entry-index> interface <interface-name>

Step2 Configure the owner’s name of the RMON ethernet statistics table.

set protocols snmp rmon statistics <entry-index> owner <string>

Step3 Commit after completing all the above configurations.

commit

Step4 View RMON Ethernet statistics information.

run show rmon statistics [<entry-index>]

Configuring RMON History Statistics

Step1 Configure RMON history statistics on a specified interface.

set protocols snmp rmon history <entry-index> interface <interface-name>

Step2 Configure the sampling interval of RMON history statistics.

set protocols snmp rmon history <entry-index> interval <interval>

Step3 Configure the history statistics table capacity, that is, the maximum number of records that the history table can hold.

set protocols snmp rmon history <entry-index> buckets <number>

Step4 Configure the owner’s name of the RMON history statistics table.

set protocols snmp rmon history <entry-index> owner <string>

Step5 Commit after completing all the above configurations.

commit

Step6 View RMON history statistics information.

run show rmon history [<entry-index>]

Configuring RMON Alarm

To configure RMON alarm function, users need to configure both RMON event definition function and RMON alarm threshold setting function. The RMON alarm threshold setting function configures the monitoring object and threshold. The RMON event definition function defines the action whether to record a log or send a trap information to the NMS when a RMON alarm event triggered.

Configuring RMON Event

Step1 Configure the community for the RMON event.

set protocols snmp rmon event <entry-index> community <community>

Step2 Configure the RMON event action type.

set protocols snmp rmon event <entry-index> type <none | log | trap | log-trap>

Step3 Enable SNMP trap. If the event is triggered and the event action type is trap or log- trap, an SNMP trap will be sent to the management station. The value of community and security-name here should be the same as the community in step 1.

set protocols snmp community <community>

set protocols snmp trap-group targets <ip_address> security-name <security-name>

Step4 Configure the description for the RMON event.

set protocols snmp rmon event <entry-index> description <event_description>

Step5 Configure the owner’s name of the RMON event.

set protocols snmp rmon event <entry-index> owner <owner>

Step6 Commit after completing all the above configurations.

commit

Step7 View RMON event and event log information.

run show rmon events [<entry-index>]

run show rmon eventlog [<entry-index>]

Configuring RMON Alarm

Step1 Configure the OID of the RMON alarm.

set protocols snmp rmon alarm <entry-index> variable <oid-variable>

Step2 Configure the sampling type of RMON alarm.

set protocols snmp rmon alarm <entry-index> sample-type <absolute | delta>

Step3 Configure the sampling interval of RMON alarm.

set protocols snmp rmon alarm <entry-index> interval <interval>

Step4 Configure the rising threshold of the RMON alarm, and the event to fire when the rising threshold is crossed.

set protocols snmp rmon alarm <entry-index> rising-threshold <alarmRisingThreshold>

set protocols snmp rmon alarm <entry-index> rising-event-index <alarmRisingEventIndex>

Step5 Configure the falling threshold of the RMON alarm, and the event to fire when the falling threshold is crossed.

set protocols snmp rmon alarm <entry-index> falling-threshold <alarmFallingThreshold>

set protocols snmp rmon alarm <entry-index> falling-event-index <alarmFallingEventIndex>

Step6 Configure the owner’s name of the RMON alarm.

set protocols snmp rmon alarm <entry-index> owner <owner>

Step7 Commit after completing all the above configurations.

commit

Step8 View RMON alarms information.

run show rmon alarms [<entry-index>]
