Hi,   Initially we only suffered this on the MS425 despite Meraki extended the impact to some other MSXXX series.  The solution proposed was a combination of new firmware release (but as you will see it is not yet available as stable, only as beta) with a possible replacement of the SFP (if it is a Meraki one, of course).  However, please bear in mind in case of replacement that for Meraki is not easy to control which are the SFP impacted and which not. I mean, considering SKU  MA-SFP-1GB-TX I am not sure if Meraki has a clear control or can identify which are impacted ... View more

Thanks a lot for the feedback @akh223.   In our case we are facing the same situation with additional problem on top. We insert the Copper SFP until possible, the SFP is detected by the MS, the port provide link and everything works. But, if that link fails down, for example because the remote device turns off or because remote disconnection, there is no way to recover it unless you "unplug" the SFP and insert it again. It is the only way to recover the link, phisically disconnect it from the MS and insert it again.   That behavior has been reproduced in several MS425 in different location and with the old MS 12.28.1 and also with the newest stable MS 14.31. In all of them we suffer from the lack of "lock in" of the Copper SFPs.   Have you suffered the same issue? ... View more

Hi @akh223 ,   One question. Independently of not being able to reach the lock in mechanism with the SFP are you still able to get link from the switch? ... View more

Hi @UCcert,   I was providing the 8 sensor per MV or MR number based on the MT Frequently Asked Questions webpage from Meraki.   Regarding the question "How many sensors can be used per gateway?" it is stated that it is recommended to have a maximum of 8 sensors per gateway to ensure connection quality.   I have to recognize that I have not checked in a real environment this number. Therefore, I can only refer to the document.   The good point is that 7 or 8 are at least bigger numbers than the 6 stated by @NGleich    https://documentation.meraki.com/MT/MT_Frequently_Asked_Questions ...

Hi NGleich,   As far as I know the MV and MR are able to support up to eight sensors each to ensure connection quality. I suppose it is not yet enough for what you are looking for but it is a little bit more than six anyway.   Hope it helps,   KR,   Raúl ... View more
