# Add an extended alarm entry in the fifth line of the extended alarm table. 
Perform operation on the corresponding variant by means of the formular 
((.1.3.6.1.4.1.43.45.1.6.1.2.1.1.2.1-.1.3.6.1.4.1.43.45.1.6.1.2.1.1.3.1)*100/.1.3.

interface 1/1/1. Monitor the operation results at the sampling interval of 10 
seconds. When the variation rate exceeds the upper threshold 50, trigger event 1; 
when the variation rate gets below the lower threshold 2, trigger event 2. Set the 
alarm instance sampling type to "forever", and set the owner of the extended 
alarm table to "user1".

RMON statistic management concerns the statistics and monitoring of the usage 
and error on a port. Statistics includes collision, undersized or oversized packet, 
timeout, fragment, broadcast, multicast, unicast, and bandwidth utility.

You can use the display rmon statistics command to view information about 
statistics table entry.
