Configuring Traffic Mirroring

Traffic mirroring allows the user to configure the switch to send copies of packets on a port that is being
mirrored to the mirroring port. The mirroring can be port-based or flow-based.
Use the Traffic Mirroring menu page to define port mirroring sessions and configure flow-based
mirroring.
To display this page, click Switching → Traffic Mirroring in the tree view. The Traffic Mirroring menu
page contains links to the following features:

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.
To display the Port Mirroring page, click Switching → Traffic Mirroring → Port Mirroring in the tree
view.
