Setup Guide
Dell EMC Networking OS Behavior: In Dell EMC Networking OS versions prior to 8.2.1.0, the MAC address that Dell EMC Networking
systems use to overwrite the Bridge Group Address on ingress was non-congurable. The value of the L2PT MAC address was the Dell
EMC Networking-unique MAC address, 01-01-e8-00-00-00. As such, with these Dell EMC Networking OS versions, Dell EMC Networking
systems are required at the egress edge of the intermediate network because only Dell EMC Networking OS could recognize the
signicance of the destination MAC address and rewrite it to the original Bridge Group Address. In Dell EMC Networking OS version 8.2.1.0
and later, the L2PT MAC address is user-congurable, so you can specify an address that non-Dell EMC Networking systems can
recognize and rewrite the address at egress edge.

Implementation Information
• L2PT is available for STP, RSTP, MSTP, and PVST+ BPDUs.
• No protocol packets are tunneled when you enable VLAN stacking.
• L2PT requires the default CAM prole.
