Configuring Port Mirroring
The page under the Mirroring link allows you to view and configure port mirroring on the system.
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.
