Use Cases

Some ports become error-disabled if their operational speeds differ. Use the speed-duplex command to align speeds and select appropriate ports for aggregation to achieve optimal bandwidth.

For example, if there are two ports, 1-Gbps and 10-Gbps, the 10-Gbps port will be error-disabled because the 1-Gbps port comes up first. If you use the speed-duplex command, the operational speed of the 10-Gbps port becomes 1-Gbps to match the lowest common speed.
