CONFIGURING LOCAL
PORT MIRRORING
Use the Interface > Port > Mirror page to mirror traffic from any source
port to a target port for real-time analysis. You can then attach a logic
analyzer or RMON probe to the target port and study the traffic crossing
the source port in a completely unobtrusive manner.

COMMAND USAGE
â—† Traffic can be mirrored from one or more source ports to a destination
port on the same switch (local port mirroring as described in this
section), or from one or more source ports on remote switches to a
destination port on this switch (remote port mirroring as described in
"Configuring Remote Port Mirroring" on page 134).
â—† Monitor port speed should match or exceed source port speed,
otherwise traffic may be dropped from the monitor port.
â—† When mirroring port traffic, the target port must be included in the
same VLAN as the source port when using MSTP (see "Spanning Tree
Algorithm" on page 203).
â—† When mirroring VLAN traffic (see "Configuring VLAN Mirroring" on
page 193) or packets based on a source MAC address (see "Configuring
MAC Address Mirroring" on page 200), the target port cannot be set to
the same target ports as that used for port mirroring by this command.
