NetBrain path calculation currently does not evaluate or carry forward Layer 2 QoS DSCP markings established at the first hop, so downstream L3 routers and SD-WAN devices such as Viptela are not assessed for DSCP inheritance during path analysis. This enhancement would extend the path calculation engine to check the L2 QoS DSCP value at the first hop and verify that it is correctly inherited by subsequent L3 or SD-WAN devices along the calculated path. Customers relying on QoS-based traffic prioritization would gain accurate end-to-end path visibility into DSCP handling, improving confidence in SLA compliance and reducing manual verification during performance troubleshooting.
