Introduction
This document explains why do we get fault F0935 and the workaround/fix for the issue.

Problem
If you have multiple Named VLANs with same VLAN ID and you restrict permission of one of the named VLANs to an org or sub-org, we'll get this alarm. If there are more than one Named VLANs with same VLAN ID, all the Named VLANs (with same VLAN ID) should have same VLAN permission restrictions OR none of them should have VLAN permission restrictions.

For Example: If we have 2 named VLANs with the same VLAN ID 40 (we’ll create) and you have set permission on one of them to restrict to a specific org/sub-org.
Created 2 Named VLANs (test-vlan and prmt-vlan) with VLAN ID “40”.
UCSmin-B# scope eth-uplink
UCSmin-B /eth-uplink # create vlan test-vlan 40
UCSmin-B /eth-uplink/vlan* # commit-buffer
UCSmin-B /eth-uplink/vlan # exit
UCSmin-B /eth-uplink # create vlan prmt-vlan 40
UCSmin-B /eth-uplink/vlan* # commit-buffer
UCSmin-B /eth-uplink/vlan # exit
UCSmin-B /eth-uplink # show vlan
VLAN:
Name VLAN ID Fabric ID Native VLAN Sharing Type Primary Vlan Multicast Policy Name Compression Type
---------- ---------- --------- ----------- ------------ ------------ --------------------- ----------------
default 1 Dual Yes None Included
prmt-vlan 40 Dual No None Included
test-vlan 40 Dual No None Included
Restricted one of the named VLAN permission to specific org “org” in our example.
UCSmin-B# scope org
UCSmin-B /org # create vlan-permit prmt-vlan
UCSmin-B /org* # commit-buffer
UCSmin-B /org # show vlan-permit
VLAN Permit:

prmt-vlan
Faults are generated “There are multiple vlans with id 40 have different accessibility configured.”

Warning F0935 2017-09-01T02:41:34.028 4210550 There are multiple vlans with id 40 have different accessibility configured.
Solution
Workaround/Fix: Either assign equal VLAN permissions restrictions or remove the restrictions from all Named VLANs with same VLAN ID. In both cases, the alarms will be cleared.
Removing VLAN permission restrictions:
UCSmin-B /org # delete vlan-permit prmt-vlan
UCSmin-B /org* # commit-buffer
UCSmin-B /org # show vlan-permit
UCSmin-B /org # top
UCSmin-B# show fault | inc vlan

Adding VLAN permission restrictions:
UCSmin-B /org # create vlan-permit test-vlan
UCSmin-B /org* # commit-buffer
UCSmin-B /org # top
UCSmin-B# show fault | inc vlan
