Monitor switch traffic load on specific port (CISCO managed switch)

Question

For troubleshooting networks problems I need to know how to monitor the traffic (work load) on a managed switch.

I read about SPAN for CISCO switches. But it seems to be overkill since it does mirror a port for further analyzing.

Then I know that there are SNMP commands to query certain switch information. This is probably a lot of manual work.

What i really need is just the traffic in mega-bit or percentage on a specific port on a cisco managed switch (WS-C2960S).

Any help is appreciated.

Answer 1

This seems exactly what you need:

show controllers utilization

Use the show controllers utilization command in EXEC mode to display bandwidth utilization on the switch or specific ports.

show controllers [interface-id] utilization
