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.
