MES3000 Ethernet switch series 115
 PDU-frame is transmitted to all VLAN ports with enabled tunneling
 Encapsulated PDU-frame (initial frame with Destination MAC-address changed to tunneling) is
transmitted to all VLAN ports with disabled tunneling.
If setting is disabled:
 PDU-frame is transmitted to handler of corresponding protocols.
Decapsulation
1. Ethernet-frames (with destination MAC address) interception is implemented on CPU. Destination
MAC-address is set by l2protocol-tunnel address xx-xx-xx-xx-xx-xx command. Interception is enabled
only when at least one port have enabled l2-protocol-tunnel setting (regardless of the protocol)
2. Interception of packet with destination MAC address xx-xx-xx-xx-xx-xx:
 l2 protocol is defined from packet's header in L2PT subsystem
 L2PT subsystem checks whether l2protocol-tunnel setting is enabled on the transmitting port or not
If setting is enabled:
 port, from which encapsulated PDU-frame was received, is blocked by l2pt-guard.
If setting is disabled:
 Decapsulated PDU frame is transmitted to all VLAN ports with enabled tunneling
 Encapsulated PDU frame is transmitted to all VLAN ports with disabled tunneling

Ethernet-interface configuration mode commands
- STP protocol must be disabled on boundary interface (spanning-tree disable)
- Boundary interface must be set in access or customer mode.
Command line request in Ethernet -interface and group ports configuration mode interface appears
