We are having issue with Meraki MX84 uplink every two weeks or so where we get about 25% packet loss which keeps growing. Reached out to ISP and they show incomplete frames with CRC errors which would indicate that one end is set to half duplex. ISP sets their side to full duplex and so do we. I have swapped out the cable, switched port to half duplex and then back to full and packet loss dropped to 0%. However 2 weeks later we see the same behavior. Has anyone seen this issue before? Would this indicate FW going bad? Thanks in advance!
