NOTE: - The guest VLAN function can take effect only in 802.1X and MAC address authentication.
- When free IP subnets are configured, the guest VLAN function becomes invalid immediately.
- If the authentication function of the built-in Portal server is enabled, the guest VLAN cannot be configured on interfaces.
- The guest VLAN function takes effect only when a user sends untagged packets to the device.
- Different interfaces can be configured with different guest VLANs. After a guest VLAN is configured on an interface, the guest VLAN cannot be deleted.
- To make the VLAN authorization function take effect,
the link type and access control mode of the authentication interface
must meet the following requirements:
- When the link type is hybrid in untagged mode, the access control mode can be based on the MAC address or interface.
- When the link type is access or trunk, the access control mode can only be based on the interface.
