RMON support 11

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 Brocade Layer 2 Switch or Layer 3 Switch.

The statistics group collects statistics on promiscuous traffic across an interface. The interface group collects statistics on total traffic into and out of the agent interface.

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.

Brocade#show rmon statistics

Syntax: show rmon statistics [ethernet <stack-unit>/<slot>/<port>]

Specify the Ethernet port in the <stack-unit>/<slot>/<port>format. Stack-unit is 1.

You can use the physical port number or the SNMP port number. The physical port number is based on the product. The SNMP numbers of the ports start at 1 and increase sequentially.

This command shows the following information.

ParameterDefinition

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.
Broadcast pkts	The total number of good packets received that were directed to the broadcast
	address.
	This number does not include multicast packets.
Multicast pkts	The total number of good packets received that were directed to a multicast address.
	This number does not include packets directed to the broadcast address.
