Symptom
Similar syslog is observed:
%SESSION_MGR-5-FAIL: Chassis 1 R0/0: wncd: Authorization failed or unapplied for client (xxxx.xxxx.xxxx) on Interface capwap_xxx AuditSessionID xxxx. Failure Reason: VLAN Failure. Failed attribute name 192_168_0_0-XXX.
Conditions
ISE is configured with Vlan name, in case of fabric, vnid is not mapped to vlan name
Workaround
Instead of using vlan name use the attribute "Airespace-Interface-Name" with the vlan name as the value for the switch to pick up vnid as vlan name in case of fabric.
Access Type = ACCESS_ACCEPT
Airespace-Interface-Name = 100
or
We can use cisco-av-pair bsn-vlan-interface-name with value of the vnid name.
Access Type = ACCESS_ACCEPT
cisco-av-pair = bsn-vlan-interface-name=100
