ONFIGURATION
The switch can mirror traffic from a source port to a target port, packets
containing a specified source address from any port on the switch to a
target port, or traffic from one or more source VLANs to a target port. (Port
mirroring and MAC address mirroring are described in this section. For
information on VLAN mirroring see “ Configuring VLAN Mirroring .”)

IRRORING
Use the Port > Mirror Port Configuration 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.

Traffic can be mirrored from one or more source ports to a destination
port on the same switch.
Monitor port speed should match or exceed source port speed,
otherwise traffic may be dropped from the monitor port.
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" ).
When mirroring VLAN traffic (see "Configuring VLAN Mirroring" ) or
packets based on a source MAC address (see "Configuring MAC Address
Mirroring" ), the target port cannot be set to the same target ports as
that used for port mirroring by this command.
When traffic matches the rules for both port mirroring, and for
mirroring of VLAN traffic or packets based on a MAC address, the
matching packets will not be sent to target port specified for port
mirroring.
