PSE: GNSS on IE-5000 / Catalyst IE-9300 In Stacked Configurations

[BrianSekleckiGE]

Pre-Sales Engineering Question:

When the IE-5000 ( H-Stacked ) and/or the Catalyst IE-9300 (IE-9320-22S2C4X with GPS/GNSS, StackWise) are Stacked, how does the combined switch IOS-XE instance deal with the presence of two GNSS receivers?

For simplicity-sake, presume a 2-switch stack (limitation of the IE-5000 H-Stack anyway).

• Under normal operations scenario: Are they both available and if the signal is lost in one, the other takes over feeding NTP and PTP refclock?  How does it pick which one to use?
• Hardware Fault Scenario: If the StackWise Master's GNS/GPS is being used under normal operations, and the Master switch crashes, does it automatically fail over to the GNS/GPS in another switch in the stack?
• Lastly PTP: Any chance they can operate independently, with the combined IOS-XE OS stack announcing PTP Grandmaster with two different priorities, one PTP instance associated with one receiver?

Thanks, ~Brian

Well, I may have answered one of my own questions:

Apparently Stackwise stacking disabled protocols PTP, PRP, and CIP on the IE-9300.  At least in the current firmware.

PTP over IE9320 stack is on the roadmap.  No time frame for release.

will ensure dual GNSS receiver is covered and if not it will be documented.

PS: thanks for reading the documentation.
