a: The 40GE optical interfaces work in auto-negotiation mode by default when they are connected to high-speed cables. If the interfaces on the peer device do not support auto-negotiation, run the negotiation disable command to disable the local 40GE optical interfaces from working in auto-negotiation mode.

NOTE:
  • CX11x switch module GE switching plane and CX31x&CX91x series switch module 10GE switching planes do not support GE optical interfaces. The CX11x switch module GE switching plane do not support 10GE electrical interfaces, and the CX31x&CX91x series switch module 10GE switching planes do not support GE electrical 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.
  • When a 10GE optical interface connects to a GE copper module, switches cannot connect to 10M/100M interfaces.
  • When a 10GE optical interface connects to a 10G optical module or high-speed cable, the interface works in non-auto-negotiation mode by default. The interface cannot be configured to work in auto-negotiation mode. If the remote interface supports auto-negotiation, the remote interface may not become Up and the local interface becomes Up. It is recommended that both interfaces work in non-auto negotiation mode so that traffic can be correctly forwarded.
