To enable err-disabled ports on Cisco 3750 switch series. NBAR is quite similar in nature. n accordingly. That’s a whopping 640Gbps of test traffic. Preconfigure switches for zero-touch deployment 2. Analyze traffic on switch ports with SPAN and RSPAN. The connected device may have been powered off at the time the port was checked. A SPAN port is. Max of 6 SPAN Sessions can be created in a CISCO Switch. This document provides a sample configuration and verification for the port-based traffic control features on your Catalyst 3550/3560 Series Switches. Sorry about that.
