Hello,
I'm currently facing an intermittent issue with a link going down and then coming back up on the CCR2004-16G-2S+ RouterOS 7.11, affecting both the WAN and LAN ports and consequently impacting the service.
I've taken several steps to address the problem:
-Replaced the cables.
-Manually configured the interface speed to 1 Gbps after disabling auto-negotiation.
-Deactivated loop protection.
-Restarting the device.
Example of the recurring log entries appear as follows every few minutes:
22:16:44, interface, info ether1- link down.
22:16:47, interface, info ether1- link up (speed 1G, full duplex).
I'm actively working on resolving this issue to restore stable connectivity.
any help is appreciated
Thank you
