Configuring Port Mirroring
Use the port mirroring feature to send network traffic on a port copied to another
port for analysis by a network analyzer.
A mirroring session consists of a
destination probe port
and at least one
source
port
. A mirror copy of the traffic on the source port(s) being probed are
transmitted from the source port to the destination probe port. A network analyzer
can be connected to a destination probe port to analyze network traffic.
A port configured as a destination probe port acts as a mirroring port as long as
the session is operationally active. When the session is not active, the port
transmits and receives traffic based on the other configuration parameters.
NOTE
When a port is configured as a probe port, the switch does not forward or receive
any traffic or respond to a ping.
