type for PVCs. You cannot use this encapsulation type for SVCs.
LLC Encapsulation inserts an LLC SNAP header for each legacy LAN
network type that is being encapsulated onto ATM. LLC Encapsulation is
desirable when it is not feasible for a larger number of VCs to be supported,
due to ATM device capacity limitations or other outside factors.
