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 is configured by selecting a specific port to copy all packets, and different ports from
which the packets copied. Before configuring Port Mirroring, note the following:
When a port is set to be a target port for a port-mirroring session, all normal operations on it are
suspended. This includes Spanning Tree.
Before configuring Port Mirroring, note the following:
• Monitored port cannot operate faster than the monitoring port.
• All the RX/TX packets should be monitored to the same port.
The following restrictions apply to ports configured to be destination ports:
• Destination ports cannot be configured as a source port.
• Destination 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.
