• Conflicts 
Shows status of Conflicts whether exists or Not. When a Volatile 
VLAN User requests to set VLAN membership or VLAN port 
configuration, the following conflicts can occur:   
Functional Conflicts between features.   
Conflicts due to hardware limitation.   
Direct conflict between user modules.   
• VLAN User 
A VLAN User is a module that uses services of the VLAN 
management functionality to configure VLAN memberships and 
VLAN port configuration such as PVID, UVID. Currently we 
support following VLAN :   
-  CLI/Web/SNMP : This is referred as static.   
-  NAS : NAS provides port-based authentication, which involves 
communications between a Supplicant, Authenticator, and an 
Authentication Server.   
-  Voice VLAN : Voice VLAN is a VLAN configured specially for 
voice traffic typically originating from IP phones.   
-  MVR : MVR is used to eliminate the need to duplicate 
multicast traffic for subscribers in each VLAN. Multicast traffic 
for all channels is sent only on a single (multicast) VLAN.   
-  MSTP : The 802.1s Multiple Spanning Tree protocol (MSTP) 
uses VLANs to create multiple spanning trees in a network, 
which significantly improves network resource utilization 
while maintaining a loop-free environment.
