How to configure the IP address for an Eth-Trunk interface on S series switches

8

For S series switches (except the S1700), you can configure an IP address for an Eth-Trunk interface as follows:
[HUAWEI]interface Eth-Trunk 10
[HUAWEI-Eth-Trunk10]undo portswitch
[HUAWEI-Eth-Trunk10]ip address 10.2.2.2 24

In which views can IPSG be enabled on S series switches
IPSG can be enabled on an S series switch (except the S1700) in an interface or a VLAN view. Interface views include the Ethernet interface view, GE interface view, 40GE interface view, XGE interface view, 100GE interface view, Eth-Trunk interface view, and port group view. Example 1: Enable IPSG in the GE0/0/1 view. [HUAWEI] interface gigabitethernet 0/0/1 [HUAWEI-GigabitEthernet0/0/1] ip source check user-bind enable Example 2: Enable IPSG in the VLAN 100 view. [HUAWEI] vlan 100 [HUAWEI-vlan100] ip source check user-bind enable

The type of Eth-Trunk member interfaces on S series switches
Observe the following guidelines when adding member interface to an Eth-Trunk on S series switches (except the S1700): 1. The member interface cannot be configured with some services or static MAC address entries. For example, when an interface is added to an Eth-Trunk, the interface must use the default link type. 2. An Eth-Trunk cannot be added to another Eth-Trunk. Member interfaces of an Eth-Trunk must use the same Ethernet type and rate. Interfaces that use different Ethernet types and rates cannot join the same Eth-Trunk. For instance, GE interfaces and FE interfaces cannot join the same Eth-Trunk, but GE electrical interfaces and GE optical interfaces can join the same Eth-Trunk. 3. Both devices of the Eth-Trunk must use the same number of physical interfaces, interface rate, duplex mode, and flow control mode. 4. If an interface of the local device is added to an Eth-Trunk, an interface of the remote device directly connected to the interface of the local device must also be added to an Eth-Trunk; otherwise, the two ends cannot communicate.

Can an Eth-Trunk Be Configured with an IP Address?
By default, an Eth-Trunk is a Layer 2 interface and cannot be configured with an IP address. If an Eth-Trunk is switched to a Layer 3 interface, it can be configured with an IP address.
