Local VLANs and Local VLANs act as “holding” VLANs in the event that LAN Emulation VLAN Move connectivity is incomplete. Although local VLANs cannot be directly
established by the ATMVLAN manager, they can be activated during a VLAN Move operation involving
When Ethernet segments in a device are reassigned to a different VLAN they are detached from the LEC of the old VLAN and attached to the LEC of the new VLAN. When the new VLAN already exists in the device, then the new segments are simply added to the others.
A different situation occurs when the new VLAN does not yet exist in the device. A new LEC for the new VLAN needs to be established in the device and that LEC needs to be connected to its LES. This process can take time and in some cases may not succeed. Meanwhile, the Ethernet segments to be moved are placed in a local VLAN created to hold them temporarily. This is signified by a new VLAN icon with the label “Local VLAN” appearing on the VLAN window. The segments to be moved are inside the local VLAN icon and will appear on the destination VLAN display only when the connection to the LES is complete.

Snooping
The device or proxy enforcing a policy will first snoop the frames going throughout the device. Snooping allows the device to recognize various frames or frame contents. This information is then used in the policy resolution process.
For example: If a segment is assigned to a
