RMON support
Statistics (RMON group 1)
Count information on multicast and broadcast packets, total packets sent, undersized and
oversized packets, CRC alignment errors, jabbers, collision, fragments and dropped events is
collected for each port on a Layer 2 Switch or Layer 3 Switch.
No configuration is required to activate collection of statistics for the Layer 2 Switch or Layer 3
Switch. This activity is by default automatically activated at system start-up.
You can view a textual summary of the statistics for all ports by entering the following CLI
command.
PowerConnect#show rmon statistics
Ethernet statistics 1 is active, owned by monitor
Interface 1/1 (ifIndex 1) counters
128 to 255 octets pkts
512 to 1023 octets pkts
Syntax: show rmon statistics [ethernet <port>]
The <port> parameter specifies the port number. You can use the physical port number or the
SNMP port number. The physical port number is based on the product. If you specify a physical
port, specify the <port> variable in one of the following formats:
•
The SNMP numbers of the ports start at 1 and increase sequentially. For example, if you are using
a Chassis device and slot 1 contains an 8-port module, the SNMP number of the first port in slot 2
is 9. The physical port number of the same port is 2/1.
This command shows the following information.

The total number of octets of data received on the network.
This number includes octets in bad packets. This number does not include framing bits
but does include Frame Check Sequence (FCS) octets.
Indicates an overrun at the port. The port logic could not receive the traffic at full line
rate and had to drop some packets as a result.
The counter indicates the total number of events in which packets were dropped by the
RMON probe due to lack of resources. This number is not necessarily the number of
packets dropped, but is the number of times an overrun condition has been detected.
The total number of packets received.
This number includes bad packets, broadcast packets, and multicast packets.
The total number of good packets received that were directed to the broadcast
address.
This number does not include multicast packets.
