The statistics include the number of the following items: collisions, packets with cyclic redundancy
check (CRC) errors, undersize (or oversize) packets, broadcast packets, multicast packets, and
received bytes and packets.
With the RMON statistics management function, you can monitor the use of a port and make statistics
on the errors occurred when the ports are being used.
RMON Configuration
Before performing RMON configuration, make sure the SNMP agents are correctly configured. For the
information about SNMP agent configuration, refer to section “ Configuring Basic SNMP Functions ”.

Before adding an alarm entry,
you need to use the rmon
event command to define the
event to be referenced by the
alarm entry.

already created for a given port, you will fail to create another statistics entry with a different index
for the same port.
