Defining Port Mirroring Sessions
Port mirroring monitors and mirrors network traffic by forwarding copies of incoming and
outgoing packets from one port to a monitoring port. Port mirroring can be used as a
diagnostic tool and/or debugging feature. Port mirroring also enables switch performance
monitoring.
Network administrators configure port mirroring by selecting a specific port to copy all
packets, and different ports from which the packets are copied. Before configuring port
mirroring, note the following:
• Monitored ports cannot operate faster than the monitoring ports.
• All the RX/TX packets should be monitored to the same port.
• PowerConnect 3348 mirrors between ports 1-24 and ports 25-48 in the same unit.
Mirroring is also possible to and from ports 25-48, and to and from ports 25-48 of a
different PowerConnect 3348 or any PowerConnect 3324 port.
• PowerConnect 3348 can mirror to any PowerConnect 3324 unit as long as the source
port is not the G2 port. PowerConnect 3348 can mirror to and from another
PowerConnect 3348 unit as long as the port is in the PowerConnect 25-48 port range.
The following restrictions apply to ports configured to be destination ports:
• Ports cannot be configured as a source port.
• Ports cannot be a LAG member.
• IP interfaces are not configured on the port.
• GVRP is not enabled on the port.
• The port is not a VLAN member.
• Only one destination port can be defined.
The following restrictions apply to ports configured to be source ports:
• Source ports cannot be a LAG member.
