I hope this message finds you well. I'm currently facing a recurring issue with my MikroTik CRS354-48P-4S+2Q+. Approximately every 4 days, at different times, the device experiences a freeze. While power is present, and the ports are active, both the devices connected to it and the MikroTik itself lose connectivity. In Winbox, the device is not visible, and pinging it yields no response. Interestingly, the port on the connected device remains active. The switch connects multiple computers, phones, printers, with a relatively low traffic load.
I have checked the extended logs, but there are no apparent error messages. The only resolution is a power cycle, but this is only a temporary fix that lasts for about 4 days.
One observation is that during the freeze, I am able to connect through the management port. I've noticed that on the affected switch, the port labeled sfp-sfpplus1 goes into pause mode. In the TX Stats tab, the value of TX Pause becomes 1. Additionally, on the upstream switch (CRS326-24S+2Q) to which the problematic switch is connected, the RX Stats tab also shows a pause, with the value of RX Pause being 1.
To address this issue, suggestions include disabling Flow Control. However, it's worth noting that this parameter is already disabled on both switches for the uplink ports.
Has anyone encountered a similar problem or can provide insights into resolving this issue? Your assistance would be greatly appreciated.
