2. Configure the RMON alarms.
The following example creates an alarm that tests every sample for a rising threshold
switch(config)#rmon alarm 5 1.3.6.1.2.1.16.1.1.1.5.65535 interval 30 absolute
rising-threshold 95 event 27 owner john_smith
The following example creates an alarm that tests the delta between samples for a falling
threshold
switch(config)#rmon alarm 5 1.3.6.1.2.1.16.1.1.1.5.65535 interval 10 delta
falling-threshold 65 event 42 owner john_smith
3. Enter the copy command to save the running-config file to the startup-config file.
switch(config)#end
switch#copy running-config startup-config
Configuring RMON events
You can add or remove an event in the RMON event table that is associated with an RMON alarm
number.
To configure RMON events, perform the following steps from Privileged EXEC mode.
1. Enter the configure terminal command to access global configuration mode.
switch#configure terminal
2. Configure the RMON event.
switch(config)#rmon event 27 description Rising_Threshold log owner john_smith
trap syslog
3. Enter the copy command to save the running-config file to the startup-config file.
switch(config)#end
switch#copy running-config startup-config
Configuring RMON group statistics collection
You can collect RMON group statistics on an interface. RMON alarms and events must be
configured for you to display collection statistics. By default, RMON group statistics are not
enabled. The statistics are measured by the probe for each monitored interface on the switch.
These statistics include, but aren’t limited to:
• Packets dropped and sent
• Bytes sent (octets)
• Broadcast packets
• Multicast packets
• CRC errors
To collect RMON group statistics on an interface and enable collection history, perform the
following steps from Privileged EXEC mode.
1. Enter the configure terminal command to access global configuration mode.
switch#configure terminal
2. Enter the interface command to specify the CEE interface type and slot/port number.
