Speed and Duplex CCNA lab
We have two switches in this network scenario that are connected to each other.
On both devices, we will configure the speed and duplex settings.
Both switches are connected to each other using their Fa0/1 ports, which support a speed of 100 Mbps.
Speed and duplex settings are configured at the interface level.
On both switches, you have to adjust Fa0/1 to work in full duplex mode and also hardcode the speed to 100 Mbps.
After the configuration, verify using the tool given in the simulation.
While auto-negotiation of the device also works fine most of the time, hardcoding the speed and duplex is an important step to prevent a duplex mismatch and also to allow devices to communicate at the best possible speed. Configuring the speed is also helpful.

between switches.
Hard-coding both ends
to full / 100 eliminates
mismatch errors.
In networking, speed and duplex settings matter a lot as they define how connected devices will communicate with each other.
Below are the speeds at which switches can transfer data to connected devices:
10 Mbps
100 Mbps
1 Gbps (1000 Mbps)
10 Gbps (on supported models)
