> # Monitoring Without SPAN

> You can monitor traffic using interface fc1/1 in a Cisco MDS 9000 Family switch that is connected to another switch or host. You need to physically connect a Fibre Channel analyzer between the switch and the storage device to analyze the traffic through interface fc1/1 .

> This type of connection has the following limitations:

> - It requires you to physically insert the FC analyzer between the two network devices.
> - It disrupts traffic when the Fibre Channel analyzer is physically connected.
> - The analyzer captures data only on the Rx links in both port 1 and port 2. Port 1 captures traffic exiting interface fc1/1 and port 2 captures ingress traffic into interface fc1/1.
