PARAMETERS
These parameters are displayed:
◆ VLAN User – A software module that uses VLAN management services
to configure VLAN membership and VLAN port settings such as the
PVID or untagged VLAN ID. This switch supports the following VLAN
user modules:
■
Static: Ports statically assigned to a VLAN through the CLI, Web or
SNMP.
■
NAS: Provides port-based authentication, which involves
communications between a Supplicant, Authenticator, and an
Authentication Server.
■
MVR: Eliminates the need to duplicate multicast traffic for
subscribers in each VLAN. Multicast traffic for all channels is sent
only on a single (multicast) VLAN.
■
Voice VLAN: A VLAN configured specially for voice traffic typically
originating from IP phones.
■
MSTP: The 802.1s Multiple Spanning Tree protocol uses VLANs to
create multiple spanning trees in a network, which significantly
improves network resource utilization while maintaining a loop-free
environment.
