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 Foundry 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:
Syntax:
show rmon statistics [[<slotnum>/]<portnum>]
The <portnum> 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 on a chassis device, you
must also enter the slot number.
•
If the product is a Stackable device, the ports are numbered sequentially starting with 1.
•
If the product is a Chassis device, the ports are numbered according to slot and port. For example, the first
port in slot 1 is 1/1. The third port in slot 7 is 7/3.
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.

Octets
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.
Drop events
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.
