Optical port speeds

We support optical port speeds on optical ports with a default speed set to 10 Gbps. Ensure that total configured port bandwidth does not exceed 100GbE to avoid packet loss. Interface names follow the et-x/y/z convention, where x and y are fixed at 0, an z represents the port index. Use the [show chassis pic fpc-slow 0 pic-slot 0] CLI command to check for bandwidth issues and adjust configurations accordingly. Specify unused ports to optimize bandwidth utilization.
