Multiple Port 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
