Chapter 6. VLAN Management
based on the Generic Attribute Registration Protocol (GARP) and propagates
VLAN information throughout a bridged network.
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.
Voice VLAN: Voice VLAN is a VLAN configured specially for voice traffic
typically originating from IP phones.
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.
DMS: Shows DMS VLAN membership status.
VCL: shows MAC-based VLAN entries configured by various MAC-based
VLAN users.
Port:
The logical port for the settings contained in the same row.
Port Type:
Shows the Port Type. Port type can be any of Unaware, C-port, S-port, Custom
S-port.
If Port Type is Unaware, all frames are classified to the Port VLAN ID and tags
are not removed. C-port is Customer Port. S-port is Service port. Custom S-
port is S-port with Custom TPID.
Ingress Filtering:
Shows the ingress filtering on a port. This parameter affects VLAN ingress
processing. If ingress filtering is enabled and the ingress port is not a member
of the classified VLAN, the frame is discarded.
Frame Type:
Shows whether the port accepts all frames or only tagged frames. This
parameter affects VLAN ingress processing. If the port only accepts tagged
frames, untagged frames received on that port are discarded.
Port VLAN ID:
Shows the Port VLAN ID (PVID) that a given user wants the port to have.
The field is empty if not overridden by the selected user.
Tx Tag:
