Show Interface Counters

[Justin Reeve]

Hi,

Does the Show interface command use 32 or 64 bit counters. Only if I do an snmpget on ifHCInOctets for a sub interface the value is actualy higher than that displayed for the whole interface when executing a show interface. The only thing that I can think of is that the counters are wrapping on the show int as they are only 32 bit ?

Depends on the speed of the interface. IOS does not support 64-bit counters for interface speeds of less than 20Mbps. This means that 64-bit counters are not supported on 10Mb Ethernet ports! Only 100 Mb Fast-Ethernet and other high speed ports support 64-bit counters.
