Transparent Ethernet service
The PTP 600 Series provides an Ethernet service between the Ethernet port at a local
ODU and the Ethernet port at an associated remote ODU. The Ethernet service is
based on conventional layer two transparent bridging, and is equivalent to the
Ethernet Private Line (EPL) service defined by the Metro Ethernet Forum (MEF).
The service is transparent to untagged frames, standard VLAN frames, priority-tagged
frames, provider bridged frames, and provider backbone bridged frames. In each case,
the service preserves MAC addresses, VLAN ID, Ethernet priority and Ethernet
payload in the forwarded frame. The maximum frame size for bridged frames in the
customer network is 2000 octets.
Layer two control protocols
The PTP 600 Series is transparent to layer two control protocols (L2CP) including:
•
Spanning tree protocol (STP), rapid spanning tree protocol (RSTP)
•
Multiple spanning tree protocol (MSTP)
•
Link aggregation control protocol (LACP)
•
Link OAM, IEEE 802.3ah
•
Port authentication, IEEE 802.1X
•
Ethernet local management interface (E-LMI), ITU-T Q.933.
•
Link layer discovery protocol (LLDP)
•
Multiple registration protocol (MRP)
•
Generic attribute registration protocol (GARP)
The PTP 600 Series does not generate or respond to any L2CP traffic.
