Mirroring

Port mirroring selects the network traffic for analysis by a network analyzer. This is done for specific ports
of the switch. As such, many switch ports are configured as source ports and one switch port is configured
as a destination port. You have the ability to configure how traffic is mirrored on a source port. Packets that
are received on the source port, that are transmitted on a port, or are both received and transmitted, can be
mirrored to the destination port.
The packet that is copied to the destination port is in the same format as the original packet on the wire.
This means that if the mirror is copying a received packet, the copied packet is VLAN tagged or untagged as
it was received on the source port. If the mirror is copying a transmitted packet, the copied packet is VLAN
tagged or untagged as it is being transmitted on the source port.
Use the Multiple Port Mirroring page to define port mirroring sessions. To access the Multiple Port Mirroring
page, click System > Port > Mirroring in the navigation menu.
