Can a 10GE interface on a CE series switch connect to a GE interface

3

A 10GE optical interface can connect to a GE optical interface in the following situations:

1. The 10GE optical interface has a GE optical module installed. No other configuration is required.
2. The 10GE optical interface has a GE copper transceiver module installed and negotiates with the remote interface to use the same rate and duplex mode.

By default, auto-negotiation is enabled on a 10GE electrical interface. A 10GE electrical interface can connect to a GE electrical interface when they negotiate to use the same rate and duplex mode.

You can run the display interface [ interface-type [ interface-number ] ] command in any view to check the speed and Duplex fields of the local and remote interfaces to determine whether the two interfaces use the same rate and duplex mode.

Can GE optical modules be used on 10GE ports of CE series switches
10GE optical interface cards of the CE series switches support GE optical and copper modules. A GE optical module can only work at 1000 Mbit/s on a 10GE optical port. When a GE copper module is installed on a 10GE optical interface, the interface works as follows: - In V100R001C00, the interface cannot connect to a 10M/100M interface. - In V100R002C00 and later versions,?Interfaces 24-35 on the CE-L48XS-FDA/CE-L48XS-FD card cannot be connected to 10M/100M interfaces. Under other circumstances, 10GE optical interfaces can be connected to 10M/100M interfaces. - On the CE8860EI, CE6860EI, and CE5810EI, such an interface can only connect to a 1000M interface. - On the CE6880-24S4Q2CQ-EI, such an interface can only connect to a 100M/1000M interface. - On the CE6880-48S4Q2CQ-EI, interfaces 1 to 12 can connect to 10M/100M/1000M interfaces, whereas interfaces 13 to 48 can only connect to 100M/1000M interfaces. - On other switch models, such an interface can only connect to a 10M/100M interface.

Can a GE interface be configured as a trunk interface
A Layer 3 interface cannot be set to the trunk mode. For more information, see product documentations or consult Huawei enterprise robot through the URL: http://support.huawei.com/eirobot/.

Can 10GE optical interfaces of a switch work upon a unidirectional fiber connection
10GE optical interfaces of a switch cannot work upon a unidirectional fiber connection. A unidirectional fiber connection occurs between two 10GE optical interfaces when one interface is Down because the Rx fiber is removed, while the other interface is still Up because its Rx fiber can receive link_Up signals from the PHY layer. A switch determines the status of a 10GE optical interface according to the IEEE 802.3ae standard. As defined in this standard, the MAC layer of a 10GE optical can send local_fault and remote_fault signals. A switch can determine the link status based on only the link status of the PHY layer or based on the link status of the PHY layer and the local_fault and remote_fault signals from the MAC layer. On a Huawei switch, link status of a 10GE optical interface turns Up only when the link status of the PHY layer is Up and both the local_fault and remote_fault signals are 0. When two 10GE optical interfaces are interconnected and the Rx fiber on one interface is removed, this interface goes Down and the MAC layer of the interface generates a local_fault signal. Meanwhile, the local interface sends a fault signal to the remote interface through the Tx fiber. The remote interface receives the link_Up signal from the PHY layer and the remote_fault signal from the MAC layer. Therefore, the link status of the remote interface goes Down.
