Assume that an XGE optical interface has an XGE/GE optical module installed and the interface rate is set to 1000 Mbit/s using the speed auto 1000 command. When you run the display interface command on the interface, the command output shows that auto-negotiation is enabled. However, you cannot run the negotiation auto command to configure the auto-negotiation mode.
