Can a network hub be connected to switch port in full-duplex mode?
When troubleshooting a switch interface operating in full-duplex mode, which error condition can be immediately ruled out?
An end user complains of slow access to the network. You issue the show interface command on the port the end user is connected to and you see a lot of collisions and runts on the interface. What is most likely the cause of the problem?
An end user complains of slow access to the network. You issue the show interface command on the port the user is connected to and you see a lot of collosions and cyclic redundancy check (CRC) errors on the interface. What ca be several causes for the problem?
You connect two switches using a straight-through UTP Cat 6 cable. The port link lights between the switches are not coming on. What is the problem?
You have a port on your switch that is not working properly. You enter the show interface command on the faulty port and the port status says "errDisable." What are some possible causes for this error?
What is the cause of multiple collisions on a port?
