Ethernet bridging
This section describes how the PTP 800 controls Ethernet data, in both the customer data
network and the system management network.
Customer network
Transparent Ethernet service
The PTP 800 Series provides an Ethernet service between the data port at a local CMU
and the data port at an associated remote CMU. 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
9600 octets.
Layer two control protocols
The PTP 800 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)
PTP 800 handles IEEE 802.3 Pause frames as a special case; each CMU can be configured
to either forward (tunnel) or discard Pause frames received at the Data port. PTP 800
discards all Pause frames received at the Management port.
The PTP 800 Series does not generate or respond to any L2CP traffic.
