Rmon Statistics - H3C SR6600 Command Reference Manual

If the result is equal to or smaller than the falling threshold, triggers the event specified by the
event-entry2 argument.
Examples
# Monitor the ratio of the broadcast packets received on the interface by using the private alarm.
Calculate the private alarm variables with the (1.3.6.1.2.1.16.1.1.1.6.1*100/.1.3.6.1.2.1.16.1.1.1.5.1) formula
and sample the corresponding variables at 10-second intervals. (Broadcast packet ratio= total number of
broadcast packets received on the interface/total number of packets received on the interface. The
formula is user configurable.)
The rising threshold (80%) triggers event 1 to log the event. The falling threshold (5%) triggers event 2,
but the event defines neither log nor trap action.
Set the lifetime of the entry to forever and owner to user1.

1.3.6.1.2.1.16.1.1.1.6.1 is the OID of the node etherStatsBroadcastPkts.1, and 1.3.6.1.2.1.16.1.1.1.5.1 is the
OID of the node etherStatsPkts.1. 1 indicates the serial number of the interface statistics entry. Therefore,
if you execute the rmon statistics 5 command, you should use 1.3.6.1.2.1.16.1.1.1.6.5 and
1.3.6.1.2.1.16.1.1.1.5.5.
This example enables the RMON agent to do the following:
Samples and monitors GigabitEthernet 2/0/1.
•
If the portion of incoming broadcast packets in the total traffic crosses 80%, the system logs the
•
event. If the portion is less than or equal to 5%, the system takes no action. To view the event log,
use the display rmon eventlog command.
