How Ruijie AP change management VLAN？

Ruijie AP has a native VLANN 1, and the native VLAN1 should be the management VLAN by default.
For Ruijie AP, each VLAN you've created can be selected as management VLAN. If you want to change the management VLAN, you need to add a new VLAN first.
You can use ACL to point out a VLAN (let's say vlan2 for example) as your AP's management VLAN:
1. Create VLAN 2 (192.168.1.0 /24):

Hostname#config
Hostname(config)# interface vlan 2
Hostname(config-if-vlan2)#ip address 192.168.1.0255.255.255.0
Hostname#wr
Hostname#end

2. Use ACL to restrict administrative requests other than VLAN 2 (192.168.1.0/24)

Hostname> enable
Hostname# configure terminal
Hostname(config)# ip access-list standard acl1
Hostname (config-std-nacl)# permit 192.168.1.00.0.0.255
Hostname(config-std-nacl)# exit
Hostname(config)# line v 0 6
Hostname(config-line)# access-class acl1 in
Hostname#wr
Hostname#end
