WAN router bandwidth usage

Question:

Need some help to figure out Cisco 3560 Switch the bandwidth usage for the WAN router f2/0 interface, sending you what we have from this interface

30 second input rate 881000 bits/sec, 296 packets/sec

30 second output rate 395000 bits/sec, 292 packets/sec

1297322378 packets input, 1616261346 bytes

Received 59127 broadcasts, 0 runts, 0 giants, 0 throttles

Answer:

If you want to validate the speed of the link transmit and receive at the time you take the sample, you should only check the following lines:

30 second input rate 2952000 bits / sec, 555 packets / sec

30 second output rate 479000 bits / sec, 470 packets / sec

Here you should not add or subtract anything. As I mentioned earlier in a FastEthernet link in full duplex mode, the transmission is independent (30 seconds output rate) incoming (30 seconds input rate).

These statistics are based on bits per second as this is handled in terms of transmission in data networks.

For the snapshot you send you:

30 second input rate 2952000 bits / sec, 555 packets / sec

30 second output rate 479000 bits / sec, 470 packets / sec

That is for you reception: 2952000 bits / sec,

so if you want to refer this value in kilobits divide by 1000 and you have:

2952000/1000 = 2952 kbps

if you want to refer this value in megabits divide between 1000000 and have:

2952000/1000000 = 2.952 Mbps

Importantly, as the point referring transmission rates in data networks (x Gbps Mbps x, x Kbps, x bps) that are expressed in terms of bits, as opposed to storage that is expressed in terms of Bytes (Gbytes, Mbytes, Kbytes, bytes). It is also important to note that the second character of the velocity:

xbps = second character is "b" in lower case that which be interpreted as bits. "x" or first character can be G, g, M,m,K,k, or not exist if the rate is expressed in bits.

There are statistical tools that add these two values:

Input Ouput rate + rate to generate a total, but personally I'm not decuerdo with this and usually do not use this type of graph. Prefer separate or overlapping graphs.
