8.4.2Troubleshooting Help

Using the show mac-address-table command, it has been discovered that a port has failed to learn the MAC of a device connected to it. Possible reasons:

)The connected cable is broken. Replace the cable.

)Spanning Tree has started and the port is in “discarding” status; or the device was recently connected to the port and Spanning Tree is still under calculation. Wait until the Spanning Tree calculation finishes. The port will then learn the MAC address.

)If not the above-mentioned problem, please check for port healthy and contact technical
