A: No. The Nexus 9300v is a data center switch; it does not run MPLS. Use IOS XRv for that.
If you are on 9.3.8, the decision is nuanced. For production labs that are stable, the delta may not justify the downtime. But for new deployments, always start with the nexus9300v939qcow2 new image. nexus9300v939qcow2 new
Source: Internal lab testing, January 2025 Even with the "new" image, no software is perfect. Here are the top bugs reported in community forums for this specific build: Issue 1: Persistent Logging to VDC The default VDC logs excessively to vdc_2 even when unused. Workaround : Enter global config and run no logging logfile to suppress noise. Issue 2: Serial Console Freeze on High Traffic If you push >800 Mbps through a single virtio interface, the serial console may become unresponsive. Workaround : Use SSH for management and avoid using virsh console during stress tests. Issue 3: LACP Hangs on Port-Channel Creation When forming a vPC between two nexus9300v939qcow2 new nodes, the LACP negotiations might hang in SUSPENDED state. Workaround : Manually set lacp rate fast on both port-channels and restart the LACP module via system switchover . Advanced Configuration: Day-0 Bootstrap One of the best "new" features is the ability to auto-configure. Create a file bootstrap.cfg with: If you are on 9
