EC2 instance - nic speed

Question

I have a EC2 instance, running RHEL 8.  I would like to view
the network interface card (nic) speed from the command
line.  Is there a command that will display the speed for the
nic?   I've used the **ethtool** command, but I only get an output
of 2 lines of information - neither of which is the speed.

#  ethtool  eth0
Settings for eth0:
        Link detected: yes

Accepted Answer

The "ethernet" port that is presented to your instance is a virtual port - it's not a physical port and therefore doesn't have a speed that is negotiated (like a physical port does).

Different instance types have different networking capabilities. [The documentation](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-network-bandwidth.html) talks about how to find the available bandwidth for your instance type.
