NOTE:

The CX110 switch module GE switching plane and CX31x&CX91x series switch module 10GE switching planes do not support GE interfaces and the CX710 switch module 40GE converged switching plane only supports 40GE interfaces.

The Ethernet interfaces of CX11x&CX31x&CX91x Series switch modules all work in full-duplex mode and do not support the half-duplex mode.

The auto-negotiation capability of 10GE optical interfaces varies according to the optical modules installed. Therefore, the auto-negotiation mode configured on the interface may be different from the one that takes effect. You can run the display this interface command to check the auto-negotiation mode that takes effect on the interface.
