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

Configuring a trunk interface on a WLAN device
The following example describes how to configure a trunk interface on an AC: A trunk interface connects an AC to a switch. [HUAWEI]vlan batch 2 3 //Create VLANs. [HUAWEI]interface gigabitethernet 0/0/1 [HUAWEI-GigabitEthernet0/0/1]port link-type trunk //Set the link type of the interface to trunk. The link type of the interface is hybrid by default. [HUAWEI-GigabitEthernet0/0/1]port trunk allow-pass vlan all //Allow packets from all VLANs to pass through. By default, the interface allows only packets from VLAN 1 to pass through. [HUAWEI-GigabitEthernet0/0/1]port trunk pvid vlan 2 //(Optional) Specify VLAN 2 as the default VLAN of the interface (default: VLAN 1).
