Detect MTU Mismatch Errors with Marvis

Juniper Routing Assurance utilizes the AIOps capability of Marvis to detect Mamixum Transmission Unit (MTU) mismatches between router ports and connected devices. Marvis gathers real-time telemetry data through gNMI, then evaluates MTU errors, framing errors, and oversized frame errors.

The Marvis Actions dashboard reports events, analyzes them, and provides diagnostic details that help you pinpoint port configuration issues quickly. Administrators can proactively address MTU mismatch errors on the ingress and egress interfaces to prevent packet fragmentation and packet drops.
