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.
The above configuration implements the following:
Sampling and monitoring interface GigabitEthernet 2/0/1
If the portion of broadcast packets received in the total packets is greater than or equal to 80%, the
system will log the event; if the portion is less than or equal to 5%, the system will take no action.
You can view the event log using the display rmon eventlog command.

Description
Use the rmon statistics command to create an entry in the RMON statistics table.
Use the undo rmon statistics command to remove a specified entry from the RMON statistics table.
After an entry is created, the system continuously calculates the information of the interface. Statistics
include number of collisions, CRC alignment errors, number of undersize or oversize packets, number
of broadcasts, number of multicasts, number of bytes received, number of packets received. The
statistics are cleared after the device reboots.
To display information for the RMON statistics table, use the display rmon statistics command.
