Zero speed at the interface - 0 bits/sec

Hello. Look at the post until the end.

It is true that cisco counters:

5 minute input rate 0 bits/sec, 0 packets/sec

5 minute output rate 0 bits/sec, 0 packets/sec

do not include multicast packets?

Hello.

There is no answer, but can anyone know

considered as speed counters on the interface of cisco?

I think this should be the number of bytes multiplied by 8 and divided by time, but something is wrong.

4695622 * 8 / 305 = 1,231,634 bit / s

five-minute counter shows the rate = 304 000 bit / s

Cat6509_ABK1#clear counters gi1/1

Clear "show interface" counters on this interface [confirm]
