Before enabling Mirror/SPAN port monitoring, you must first configure a switch port to mirror traffic to. Typically, the WAN port on the core switch is configured to mirror traffic to an unused port, which is cabled to the Exinda appliance. Alternatively, a network hub can be deployed in-path, and the Exinda appliance can be cabled directly to the hub (since a hub, by design, mirrors all traffic to all ports).
Any port not enslaved to a bridge or in use for another function, for example Cluster or WCCP, may be used to receive mirror port or SPAN port traffic.
