The network board in a workstation is currently configured as follows: -Network speed = Auto -Duplexing = Auto The workstation is experiencing poor network performance and you suspect that the network board is not correctly detecting the network speed and duplex settings. Upon investigation, you find that it is running at 10 Mbps half-duplex. You know that your network switch is capable of much faster throughput. To fix this issue, you decide to manually configure these settings on the workstation. Before you do so, you need to verify the configuration of the switch port that the workstation is connected to. Given that it is a Cisco switch, which commands can be used on the switch to show a list of all switch ports and their current settings?
