Commonly Used WDS Link Fault Location Methods

Link establishment between the root AP and leaf AP is used as an example:

The root-middle-leaf networking can be considered as a combination of root-leaf APs (root-(leaf root)-leaf).

Therefore, the troubleshooting methods for root-middle-leaf scenarios are similar to the root-leaf scenarios.

The following figure shows the root-leaf networking. The WDS network is established through 5 GHz radio links.

1. A single-band AP supports a maximum of 16 VAPs, with their numbers ranging from 0 to 15. The 16 VAPs correspond to 16 separate air interface addresses. The MAC address of the air interface increases by 1 from the base address every time the VAP number increases by 1.

   If the WDS function is enabled, VAP12 and VAP13 are only used for WDS.

2. A dual-band AP supports a maximum of 32 VAPs, with their numbers ranging from 0 to 31. The 32 VAPs correspond to 32 separate air interface addresses. The MAC address of the air interface increases by 1 from the base address every time the VAP number increases by 1.

   If the WDS function is enabled on the 2.4 GHz radio, VAP12 and VAP13 are only used for WDS.

   If the WDS function is enabled on the 5 GHz radio, VAP28 and VAP29 are only used for WDS.

• The root AP provides the VAP ath 12 for the leaf AP to connect to.
• The leaf AP uses the VAP ath 13 to connect to the root AP.

Radio calibration may change the radio channels and power; therefore, radio calibration may interrupt WDS or mesh services if implemented on radios that have WDS bridges or mesh links configured.
