I have 6500 switch at a remote office. I don't have an LMS and I am unable to run Netflow because the link is very slow. I have to find out the average tx utilization and average rx utilization (in percentage) for all interfaces of the switch. How can I calculate that?
The following cisco link gives the calculation for Input & Output utilization
#show interfaces gigabitEthernet 1/1 counters will give me the InOctets & OutOctets and with a delta time of 30seconds, but I am getting a wrong value.
Thanks in advance
The formula in this tech tip is correct. Can you provide the raw numbers for input and output octets from a few polling intervals for one sample interface in addition to the ifSpeed of that interface?
