CRS226-24G-2S+ and CCR1016-12S-1S+

hi
i have setup a 5 star resort with 600 rooms and i have big problems with the fiber connection between the devices
the devices that i have in the network is

  1. CCR1016-12S-1S+ working as hotspot server with radius server and as capsman server
  2. 35 Sxt G-2HND
  3. 15 RB951Ui-2HND
  4. 9 CRS226-24G-2S+
  5. 5 CRS210-8G-2S+
  6. 10 SFP MODULES S-85DLC05D
  7. 10 SFP+ MODULES S+85DLC03D

i have the connected with fiber
suddenly i lose connection between the crs and the ccr and if i connect to crs that i can see with winbox i can see that the sfp link is running but i have no packets request from the other crs (i have tested either with auto negotiation on or off) if then i go to the next crs that i cannot see from the previous and make a restart all works ok for 1-2 hours and then the same again happens after i had this done in 1 day 12 times i have connect the crs between them with Ethernet cable all
is ok to this 2 crs that i have connect with cable and the problem goes to the next 2 crs that is connected with fiber

P.S i use 6.27 ros but i have tested and 6.28, 6.29rc,6.26

any suggestion what the problem is because all this makes me crazy

Thanks for reporting, we found that this issue started in 6.28, and will be fixed in 6.29.

Can you repeat this if both CRS and CCR have 6.27 ? And have you tested if both running 6.29rc 20 ?

If you can repeat this with 6.27 or 6.29rc20, please let me know.
