Add Private MPLS WAN LINK
In the Oracle SD-WAN Edge Configuration Editor, once users click + (Add) under Sites [Site Name] WAN Links, the Add WAN Link pop-up appears.
Figure 1 illustrates how to configure the new WAN Link Access Type of Private MPLS.
Selecting a WAN Link Access Type of Private MPLS defines the Basic Settings for the WAN Link. The configurable settings include the physical (permitted) rate for WAN Ingress and WAN Egress. The MPLS Queues cannot exceed the physical (permitted) rate values. There are also no Audit errors if the sum of all MPLS Queues is below the WAN Link physical rates. See Figure 2 for a screen shot of the defined MPLS Queues.
Figure 2: Defined MPLS
Queues
Figure 2 illustrates the Basic Settings for a Private MPLS WAN Link. Under the Basic Settings, there is now a new MPLS Queues Tab. Users click + Add to add specific MPLS Queues. These should correspond with the queues defined by the Service Provider.
Users must define the following attributes for the MPLS Queues option:
- MPLS Queue Name
- DSCP Tag: This setting should correspond to the Service Provider's DSCP tag setting for the queue.
- Unmatched: When enabled, any frames arriving that do not match defined tags within the configuration file are mapped to this queue and the bandwidth defined for this queue.
- WAN Ingress Permitted Rate: The amount of bandwidth that Oracle devices are permitted to use for upload, which cannot exceed the defined physical upload rate of the WAN Link.
- WAN Egress Permitted Rate: The amount of bandwidth that Oracle devices are permitted to use for download, which cannot exceed the defined physical download rate of the WAN Link.
When users expand the MPLS Queue definition (by clicking the +), additional options appear.
These options include:
- Tracking IP Address: WAN Link tracking address
- Congestion Threshold: The defined amount of time for congestion (in microseconds) after which the MPLS Queue will throttle packet transmission to avoid additional congestion. When congestion exceeds the set Threshold, Oracle will back off the sending rate.
- Eligibility: The MPLS Queue's eligibility to process specific classes of traffic. When eligibility is disabled for a specific class of traffic, that class of traffic is unlikely to route through the MPLS Queue unless network conditions require it.
Users should configure the MPLS Queues that correspond to the existing Service Provider WAN Link queue definitions.
Since this is a new WAN Link Access Type, any existing MPLS WAN Links that are configured prior to Oracle SD-WAN Edge 4.3 are not impacted. Users should discuss migrating to the 4.3 features if desired, but migration is not required. Please contact your implementation team or support for additional recommendations when migrating to the new WAN Link Access Type.
