UniFi Controller Software
The initial setup allows you to adopt the UniFi Switch later.
After initial setup, there are two methods available to adopt
the UniFi Switch via the UniFi Controller software:
• Over an untagged switch port by the default VLAN 1
• Over a tagged VLAN on a switch port, and you choose which
VLAN is used for management
Note: You have two management options:
• UniFi Controller Software
• CLI
You cannot use both simultaneously; otherwise,
changes may not be implemented properly.
