Troubleshooting Tips

•Link down is the superset of all other causes. A port is brought to down state if the total number of other causes equals to the number of allowed link-down failures.

•Even if the link does not flap due to failure of the link, and port guard is not enabled, the port goes into a down state if too many invalid FLOGI requests are received from the same host. Use the shut and the no shut commands consecutively to bring up the link.
