Question

A network administrator has configured a 4-port port-channel between two Dell EMC Campus networking switches. The physical interfaces show as administratively up and operationally up on both switches. However, the port-channel shows as operationally up on switch A and operationally down on Switch B. What is a potential reason for the inconsistent port-channel state?

Options

  • ASwitch A is configured to use dynamic port-channels and Switch B is configured to use static port- channels
  • BPorts in the port-channel on Switch A are at the same speed but the ports in the port-channel on Switch B are a mix of speeds
  • CSwitch A is configured using channel-group # mode on and Switch B is configured using channel-group # mode auto
  • DN-Series supports a maximum number of physical interfaces that can be included in port-channels on a per-device basis
