dhcp option 60 seems not to working

[Karl_Yealink]

Yealink phone can obtain the VLAN ID via the LLDP/CDP or Manual or DHCP VLAN.
And the priority of each method is: LLDP/CDP>Manual>DHCP VLAN.

Yealink phone use option 132 of DHCP to obtain the VLAN ID, you need to change to option 60.
You can configure it from the web interface->network->advanced->DHCP VLAN->Option (1-255)

There is also a syntax you need to configure.
network.vlan.vlan_change.enable=
Description:
Enables or disables the IP phone to obtain VLAN ID using lower priority of VLAN
assignment method or disable VLAN feature when the IP phone cannot obtain
VLAN ID using the current VLAN assignment method.
0-Disabled
1-Enabled
The priority of each method is: LLDP/CDP>Manual>DHCP VLAN.
If it is set to 1 (Enabled), the IP phone will attempt to use the lower priority of VLAN
assignment method when failing to obtain the VLAN ID using higher priority of VLAN
assignment method. If all the methods are attempted, the phone will disable VLAN
feature.
Note: If you change this parameter, the IP phone will reboot to make the change
take effect.
