parameter affects VLAN ingress processing. If the port only accepts tagged
frames, untagged frames received on that port are discarded.
• Tx Tag Shows egress filtering frame status whether tagged or untagged.
• UVID
Shows UVID (untagged VLAN ID). Port's UVID determines the packet's behavior
at the egress side.
• 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 feature.
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 are reffered 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.
