Configure Port Mirroring
Port mirroring lets you select the network traffic of specific switch ports for analysis by a
network analyzer. You can select many switch ports as source ports but a single switch port
only as the destination port. You can configure how traffic is mirrored on a source port by
selecting packets that are received, transmitted, or both.
A 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.
T
o globally enable port mirroring, specify the destination port, and specify one or
more source ports:

f-network using an Ethernet cable.
