I'm having an issue with a CCR1036 where it loses link on all copper ethernet ports after a week or so. SFP ports are unaffected luckily as my uplink is on one of those so I can get in and software reboot the system, but it does cause an outage for the local devices.
The symptoms are that copper ports simply lose link despite no changes to the servers plugged to them. The 'R' disappears from /interface print. Rebooting the box brings it back.
My firmware is old (3.10 routerboard and 6.20 RouterOS) so I'm going to update both tonight during a maintenance window, however I wondered whether anyone else had seen this issue and had any experiences they could share, please?
