1.1 statistics group
After configuring the statistics group, view statistical information
1.1.1 Configuration
1) Enable the group statistics on the interface, the interface to the statistical data
xNet#configure terminal
xNet(config)#interface ge1
xNet(config-if)#rmon collection stats 1
xNet(config-if)#end
XNET #
1.1.2 results
View statistics, and statistics show interface consistency of:
1.2 alarm event group and the group
When the sampling value of the monitored variables in the same direction repeatedly exceeds the threshold value, will only generate an alarm event for the first time, a few times will not generate an alarm event back, the rising alarm and falling alarm are alternate, there has been a rising alarm, the next time will be for the lower limit alarm.
1.2.1 Configuration
1) with a good set of statistics, statistics for event triggering
xNet#configure terminal
xNet(config)#interface ge1
xNet(config-if)#rmon collection stats 1
xNet(config-if)#exit
xNet(config)#
2) even group configuration, operation of the trigger to transmit trap
xNet(config)#
xNet(config)#rmon event 1 log trap public description test_too_much owner xNet
xNet(config)#rmon event 2 log trap public description test_too_less owner xNet
xNet(config)#end
XNET #
3) Configure alarm group, etherStatsPkts monitoring data, trigger events when etherStatsPkts value reaches a certain threshold, it will send trap
xNet#configure terminal
xNet(config)#rmon alarm 1 etherStatsPkts.1 interval 5 delta rising-threshold 10 event 1 falling-threshold 3 event 2
xNet(config)#end
XNET #
4) arranged trap receivers snmp
xNet#configure terminal
xNet(config)#snmp-server host public 10.204.253.202
xNet(config)#end
XNET #
1.2.2 results
1) Start snmptrapd process at the receiving end for receiving trap Trap
snmptrapd profile mysnmptrad.conf
{
authCommunity log,execute,net public
}
2) a distal administrator (10.204.253.202) trap message received
root@xNet-weil:/home/xnet/test# snmptrapd -c mysnmptrad.conf -f -Leo -O a
3) When the connection MIB-Browser SNMP, comm verification is unsuccessful or not match, there will be a trap
4) When the link up / down will also send trap
1.3 history group
History can set the timing of the sampling statistics and save.
Configuring
xNet#configure terminal
xNet(config-if)#rmon collection history 1 buckets 7 interval 5
xNet(config-if)#end
XNET #
1.3.2 results
History can set the timing of the sampling statistics, the administrator can view this record.
Note: If history is full, the new data will overwrite the oldest sample of a sample data record.
Content for the recently sampled seven statistical data, the following information using the MIB-Browser view:
