NX-OS always-on sandbox doesn't correctly support gRPC

[njrusmc]

Sandbox in question: https://devnetsandbox.cisco.com/RM/Diagram/Index/dae38dd8-e8ee-4d7c-a21c-6036bed7a804?diagramType=Topology

The tile text says "gRPC" and the feature is enabled, but there is no gRPC connectivity. I assume the gRPC port is being filtered. Let's open that up and add the connectivity details (auth/port, etc) to the instructions tab.

Hi @njrusmc,

This solution is unhelpful for two reasons:

1. Today, there is only one NX-OS sandbox (always-on). The reserved one no longer appears available.

2. Opening up the gRPC port in the always-on sandbox is a trivial task. What prevents the DevNet team from doing it?

Hello Nicholas, I enjoyed your white paper on MPLS. Are you still having trouble connecting via gRPC? I was able to establish a connection on port 50051 (internet connection; not on VPN).

ssh -l admin sbx-nxos-mgmt.cisco.com 50051
