Hello all,
When using Huawei WLAN devices, users generally retain the default settings to simplify configuration. For example, the default service and management VLAN IDs of an AP may be both 1. In this case, various problems may occur.
This document describes impact of APs' service VLAN and management VLAN configurations on services in tunnel and direct forwarding modes, recommended configurations, and common VLAN configuration errors. It aims to instruct users to deploy services and reduce such errors.
The following table analyzes impact of different combinations of service and management VLANs in direct and tunnel forwarding modes, and provides configuration recommendations.
NOTE:For easy description, the VLANs in the table are only examples.
Forwarding Mode | Service VLAN | Management VLAN | Configuration Impact | Recommended Configuration |
|---|---|---|---|---|
Direct forwarding | 1 | 100 | Management VLAN tags are added to user service packets, causing service disorder. | Not recommended |
100 | 1 | Network congestion may occur due to the large broadcast domain of VLAN 1 and broadcast flooding, affecting user experience. | Not recommended | |
1 | 1 | Network congestion may occur due to the large broadcast domain of VLAN 1 and broadcast flooding, affecting user experience. | Not recommended | |
100 | 100 | Data is incorrectly forwarded. | Not recommended | |
100 | 50 | Recommended standard configuration. | Recommended | |
Tunnel forwarding | 1 | 100 | Network congestion may occur due to the large broadcast domain of VLAN 1 and broadcast flooding, affecting user experience. | Not recommended |
100 | 1 | Network congestion may occur due to the large broadcast domain of VLAN 1 and broadcast flooding, affecting user experience. | Not recommended | |
1 | 1 | MAC address flapping occurs, causing incorrect data forwarding. | Not recommended | |
100 | 100 | MAC address flapping occurs, causing incorrect data forwarding. | Not recommended | |
