VLAN Attributes

The VLAN attributes page within the Common Objects menu allows additional configurations to be defined on a per VLAN basis within a network policy. VLAN attributes are applied when the VLAN is defined within an assigned port type or when the VLAN deployment option is enabled. If dynamic VLANs are utilized, then the VLAN deployment option can enabled within the VLAN attributes page to apply VLAN settings. A VLAN defined within Instant Port Profiles as Non-Forwarding will not apply VLAN attributes.

Override VLAN attributes for a single device through the Switch template. The override feature can apply to different port configuration VLAN attribute settings. Inherited VLANS can be modified but not deleted.

The VLAN Attributes page shows six columns:

VLAN ID - The numerical identification number of the VLAN
VLAN Name - The name of the VLAN
IGMP Snooping VLAN Settings - Allows the switches to identify ports to which multicast group member hosts are attached to optimize the distribution of multicast traffic
DHCP Snooping VLAN Settings - Enables snooping of DHCP packets and creates a DHCP bindings database of IP to MAC addresses for this VLAN
VLAN Deployment - Allows VLAN and VLAN attributes to be created on switches when no port types are assigned with the defined VLAN
Note
VLAN Deployment is disabled by default.
