VLANs

The VLAN Identifier is used to identify the VLAN in tagged Ethernet frames according to IEEE 802.1Q.

VLAN Name

Synopsis: Any 19 characters

Default:

The VLAN name provides a description of the VLAN purpose (for example, Engineering VLAN).

Forbidden Ports

Synopsis: Any combination of numbers valid for this parameter

Default: None

These are ports that are disallowed to be members of the VLAN. Examples:

None - all ports of the switch are allowed to be members of the VLAN

2,4-6,8 - all ports except ports 2,4,5,6 and 8 are allowed to be members of the VLAN

IGMP

Synopsis: { Off, On }

Default: Off

This parameter enables or disables IGMP Snooping on the VLAN.

MSTI

Synopsis: 0 to 16

Default: 0

This parameter is only valid for Multiple Spanning Tree Protocol (MSTP) and has no effect, if MSTP is not used. The parameter specifies the Multiple Spanning Tree Instance (MSTI) that the VLAN should be mapped to.

Note: If IGMP Snooping is not enabled for the VLAN, both IGMP messages and multicast streams will be forwarded directly to all members of the VLAN. If any one member of the VLAN joins a multicast group then all members of the VLAN will receive the multicast traffic.
