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 device.
No configuration is required to activate collection of statistics for the device. 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 [<num> | ethernet <slot/port> | management <num> | | begin
<expression> | exclude <expression> | include <expression>]
The <portnum> parameter specifies the port number. You can use the physical port number or the
SNMP port number. 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, 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.
TABLE 183 Export configuration and statistics
This line... Displays...
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.
Packets The total number of packets received.
This number includes bad packets, broadcast packets, and multicast
packets.
