Port Mirroring Configuration
You can mirror the traffic from a target port to an analysis port for real-time
analysis. You can then attach a logic analyzer or RMON probe to the analysis port
and study the traffic crossing target port in a completely unobtrusive manner.
When mirroring a port, note that the analysis port must be included in the same
VLAN as the monitored port.
Use Port Monitoring Configuration to set up analysis ports as shown below:
Parameter Description
Capturing State Enables or disables the mirror function.
Analyzer Port The port that will "duplicate" or "mirror" all the traffic happening on the monitored
port.
Analyzed Port The port whose traffic will be monitored.
Port Statistics
Use the Port Statistics menu to display Etherlike or RMON statistics for any port on
the switch. The statistics displayed are indicated in the following figure and table.

Etherlike Statistics

Etherlike Statistics display key statistics from the Ethernet-like MIB for each port.
Error statistics on the traffic passing through each port are displayed. This
information can be used to identify potential problems with the switch (such as a
faulty port or unusually heavy loading). Values displayed have been accumulated
since the last system reboot.
