I am using a CRS309 (using SWOS 2.10) as my core switch, off of which I have various Ubiquiti / TP-Link switches / APs connected. Today I have run into a situation that required me to reboot my CRS309 twice due to all of my downstream devices going offline.
It seems that communication on/to the CRS309 went in and out twice today, and I would know exactly when it would happen as all of my Ubiquiti devices (switches/APs) would alert to the outage. My Main PC is connected directly to the CRS309, and I was able to get sporadic communication to the CRS309 as I tried to determine what the problem was. Pings from my main PC would sometimes work to the CRS309, and other times not. Sometimes I was able to bring up the CRS309 web page, other times it would just hang. Both times all of the issues were resolved when I reboot the CRS309 via the web page (when I could get it up). Both times the reboot fixed everything and all worked normally after.
Any ideas? Temps on the CRS309 are typically in the 32-34C range, and I am using Cisco SR modules and 1 10Gtek DAC. (I have two other CRS309’s in my network downstream as well, no issues so far with them.)
