Use the Interface > Port > Mirror page to mirror traffic from any source

Traffic can be mirrored from one or more source ports to a destination

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

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.
