I have a PTP450i link that will drop a few times every day. Spectrum is clear. Power levels are perfect and the distance is short. I have changed cables, psu and even the link but still having the same issue. Its running on 16.2.2. When its operating its perfect.
Hi, thank you for the response.
Yes, i can change the software patch. I’m unsure why it is showing as the recommended software patch on the Maestro for this if its not the recommended software patch?
i have moved them back to 16.1.1 and will monitor. Thank you for the help.
We have had a long standing issue of having occasional sesion drops in strong signal conditions. This would depend upon the data traffic pattern and most susceptible to happen at 8X links. This has been addressed in release 20.0. The 20.0 Beta Release Notes read:
Improved Link Performance
A new encoding/decoding introduced in 20.0 improves the performance of the link in a variety of traffic payloads. It also decreases the likelihood of lower modulation or a dropped session due to a specific packet payload. For this reason, we recommend that SMs are upgraded first. If the AP is upgraded first, each link will run at a max of 2X MIMO-B until the SM side is also upgraded. As always, it is recommended that both sides of the link be running the same software version.
Would you mind being able to try the latest R20 beta and letting me know how the sessions are?
Another workaround in debugging could be to limit the max rate to 6X and monitoring the sessions. In R20 this will not be needed, can run at full 8X.
It was stated in this thread that 16.2.2 is for PMP and therefore should not be used for PTP450i. Is this correct? I generally assume that 450 software versions apply to both PMP450 and PTP450. (In our case we are mainly using PMP450i and PTP450i.) When we import software into our on-prem cnMaestro I don’t import different software for PMP and PTP. I did a (very) quick scan of 16.2.2 release notes and I didn’t see anything saying not to use it for PTP.
OK, that makes sense now. I was confused as to whether or not I was doing the right thing by applying the the same software patch to PMP450 and PTP450. I will would be inclined to try the R20 beta and see how it goes as I’ve had the same issue on other links with different software patches.
Really hope this solves the problem because when the links work they perform really well.
