Mismatch in Native VLAN configuration on the AP and Switch

Resolution

When an IEEE 802.1Q trunk port is used, all frames are tagged except those on the VLAN configured as the "native VLAN" for the port. Frames on the native VLAN are always transmitted untagged and are normally received untagged. Therefore, when a Cisco Access Point (AP) is connected to the switchport, the native VLAN configured on the AP must match the native VLAN configured on the switchport.

For detailed information on how native VLANS works, refer to the Significance of Native VLAN section of Using VLANs with Cisco Aironet Wireless Equipment.

Note: If there is a mismatch in the native VLANs, the frames are dropped.

For more information related to VLANs, refer to Configuring VLANs.

For information on how to configure VLANs on bridges, refer to Configuring VLANs.

For configuration commands VLANs, refer to VLAN Configuration Example section of Configuring VLANs.
