Best Answer
The show interface command will give you 5 minute input and output bandwidth
If you want to create a graph of the bandwidth, use something like MRTG to set up regular polling of the interface traffic through SNMP. MRTG will create a nice graph of the data i.e.
To enable PRTG, set up a Read-Only community string on the switch:
Then configure the device in PRTG using the following settings:
There are other options which allow you to look at the bandwidth of individual traffic flows on a port such as IP accounting and NetFlow, although these do not usually work properly on L3 switches as they rely on traffic being process switched.
