MPLS-TP In FOXMAN‑UN
Supported Features
The current FOXMAN‑UN release supports the following key features:
− Static network provisioning.
− Creation of Virtual Private Wire Service (VPWS).
− Creation of Virtual Private LAN Service (VPLS).
− Provisioning of tunnel between two nodes in the MPLS-TP enabled network. The provisioned tunnel can have a working and an optional protection Label Switched Path (LSP).
− Bandwidth management at the link level.
− Bandwidth management at Pseudo Wire level.
− VPLS services synchronization.
− Bridge Ports, VLANs and SVIs synchronization.
− All MPLS-TP LSPs are bidirectional co-routed as detailed in RFC5654.
− LSP manual or automatic routing. The recommended case is for FOXMAN‑UN to automatically calculate the working and protecting paths.
− LSPs are monitored through the use of OAM.
− 1:1 LSP bidirectional protection with sub-50 ms recovery.

Please note:
When using core unit redundancy with Ethernet stand-alone service units, FOXCST configuration instructions as described in the following example should be adhered to:
• Assume an Ethernet stand-alone service unit is assigned in slot 5. In this case the stand-alone service unit is connected to iport-5 of the core units in slots 11 and 13.
→ Configure both core unit internal ports, unit-11/iports/iport-5 and unit-13/iports/iport-5, to the port type “PWAC”.
→ Configure the QoS parameters on both core unit internal ports, unit-11/iports/iport-5 and unit-13/iports/iport-5.
→ When configuring the VPWS, attach the working core unit internal port unit-11/iports/iport-5 to the Pseudo Wire.
At a core unit switch-over and with the redundant core unit becoming active, the following behavior applies:
• Traffic will flow over unit-13/iports/iport-5. However, this is not reflected in the FOXCST. FOXCST still shows unit-11/iports/iport-5 as configured “PWAC”. Even if the working core unit is not plugged in slot-11, FOXCST still shows unit-11/iports/iport-5 as configured “PWAC”.
• Statistics counters are available on unit-13/iports/iport-5.
Limitations
The current FOXMAN‑UN release does not support the following MPLS-TP features:
− Modifications of labels (LSP and Pseudo Wire).
− Re-routing.
