Symptom
Cat9800 WLC. The clients can't connect to a Flex WLAN and or SSID will not broadcast.
show logging displays:
Nov 29 21:31:41.269: %SESSION_MGR-5-FAIL: Chassis 1 R0/0: wncd: Authorization failed or unapplied for client (xxxx.xxxx.xxxx) on Interface capwap_90000004 AuditSessionID 00000000000000196154D1F7. Failure Reason: VLAN Failure. Failed attribute name VLAN2673.
Conditions
Site TAG has Local Site disabled.
The VLAN that you want to assign to the client exists in the WLC and at the AP, but the name is different.
For example:
At the WLC:
vlan 2673
name VLAN2673
At the Flex Profile you add the VLAN 2673 using the name "Corporate"
Workaround
Configure the same VLAN name at the WLC and at the Flex Profile.
Or, instead of selecting the VLAN from the dropdown at the Policy Profile, manually enter the VLAN ID. For example 2673.
Further Problem Description
This is not a bug and is expected behavior.
You have to define the vlan name mapping in the flex profile as well
