On a network switch, the port mirroring function sends copies of network packets from one port to another switch or port for analysis.
Port mirroring is a safe, effective way to mirror traffic to CA ADA monitoring devices.
Some switches do not provide the diverse range of TCP packet mirroring capabilities that these scenarios require.
Where traffic cannot be mirrored optimally, use alternatives such as fiber taps.
Note: The port mirroring function on Cisco switches is named Switched Port Analyzer (SPAN).
Mirror the switch ports, where traffic travels to and from the monitored servers, to the monitor NIC on the CA ADA server or to the ports where CA ADA monitoring devices are connected. When mirror ports are configured correctly, CA ADA monitors the flow of application traffic between clients and servers without the use of desktop or server agents.
