I have a MikroTik CRS312-4C+8XG running as a switch on RouterOS 7.13.4.
Uplink on SFP+ port 1 to a Unifi switch and gateway.
Interestingly / annoyingly:
- Internet works upstream (in the unifi part of the network)
- Internet sometimes works from the Mikrotik switch but drops off now and then (and it has been down for a while now)
- I can access my entire network from the Mikrotik switch, but not the internet
- When trying to checking for updates on the switch, I get a 'could not resolve dns name' error
(I have tried purging the DNS cache, without effect.)
See below more details. Thanks!
