In reference to: http://www.cisco.com/c/en/us/support/docs/ip/simple-network-management-protocol-snmp/8141-calculate-bandwidth-snmp.html

Looking at the input and output utilization. for instance if my number of seconds is 60

It says: Input utilization = ((ifInOctets * 8) * 100) / (60 * ifspeed)

What metric does it want for Ispeed? Megs? bytes? Gigs?
