Hi there!
The management interface is a Layer 3 interface that can be configured with an IP address. To configure an IP address for the management interface, you can run the following commands:
<huawei> system-view
[HUAWEI]interface meth 0/0/1
[HUAWEI-MEth0/0/1] ip address 192.168.1.2 24
But only some switch models have management interfaces.
