Packets transmitted on a WLAN include management packets and service data packets.
It is recommended that you use different VLANs for the management VLAN and service VLAN.
You are not advised to use VLAN 1 as the management VLAN or service VLAN.
In tunnel forwarding mode, management VLAN and service VLAN must be different.
In actual WLAN networking, management VLANs and service VLANs must be properly planned. The following example assumes that an AP connects to an AC through a Layer 2 network.
In direct forwarding mode, ensure that the AP can exchange management VLAN packets with the AC and exchange service VLAN packets with upstream devices.
In tunnel forwarding mode, ensure that the AP can exchange management VLAN packets with the AC and the AC can exchange service VLAN packets with upstream devices.
Networking restrictions
In tunnel forwarding mode, the AC and AP do not support IP packet fragmentation.
- In the AC AP networking, to prevent loops, port flapping, or AP disconnection, do no use Smart Link, equal-cost routing, or port protection services.
- The AC cannot manage APs through VPNs. That is, the source interface can not be added to a VPN.
