Perform the following configuration in VLAN view.
By default, the system adds all the ports to a default VLAN, whose ID is 1.
You can add or delete trunk port and hybrid ports to or from a VLAN by the port
and undo port commands in Ethernet port view, but not in VLAN view.

You can use the following command to set or delete the VLAN description
character string.
You can use description character strings, such as workgroup_name and
department_name, to distinguish the different VLANs.

By default, the VLAN description character string is the VLAN ID of the VLAN,
VLAN 0001. The VLAN interface description character string is the VLAN interface
name, for example, 3Com, Switch 8800, Vlan-interface1 Interface.

implement the network layer function on a VLAN interface, the VLAN interface
should be configured with an IP address and mask. For the corresponding
configuration, refer to
