Port mirroring
Port mirroring copies all received and transmitted packets (including local traffic) from a source
port to a predefined destination port, in addition to the normal destination port of the packets.
Port mirroring, also known as “sniffing,” is useful in debugging network problems.
Port mirroring allows you to define a source port and a destination port, regardless of port type.
For example, a 10 Mbps and a 100 Mbps port can form a valid source/destination pair. You
cannot, however, define the port mirroring source and destination ports as the same source
and destination ports.
You can define one source port and one destination port on each Branch Gateway for received
(Rx), transmitted (Tx), or transmitted and received (both) traffic.

Port mirroring configuration examples
The following example creates a port mirroring pair in the Branch Gateway:
G430-001(super)# set port mirror source-port 10/3 mirror-port 10/4 sampling always
direction rx
Mirroring rx packets from port 10/3 to port 10/4 is enabled
The following example displays port mirroring information for the Branch Gateway:
G430-001(super)# show port mirror
port mirroring
Mirroring both Rx and Tx packets from port 10/3 to port 10/4 is enabled
The following example disables port mirroring:
Gxxx-001(super)# clear port mirror
