Description

This article provides information about the maximum achievable throughput for interfaces in switches.

Solution

Traffic statistics: The counters displayed here indicate the total number of bytes and packets both received by and transmitted out of the interface. These numbers give you an indication of how much traffic your interface is handling.

Input bytes: Number of bytes entering the interface and the current throughput rate in bits per second (bps).

Input packets: Number of packets entering the interface and the current throughput rate in packets per second (pps).

Output bytesNumber of bytes exiting the interface and the current throughput rate in bits per second (bps).

Output packets: Number of packets exiting the interface and the current throughput rate in packets per second (pps).

To calculate the total throughput, you need to add the inbound and outbound traffic(bps) as seen on the interfaces.

 As per the calculation, for inbound traffic the throughput stands around 9.24Gbps.

 And, for outbound traffic the throughput stands around 9.23Gbps.
