We have a MikroTik CHR running in our network with third party switches ( Huawei & Cisco ) and Access points ( Aruba ). Sometimes access points are not able to ping from our CHR and it is intermittent. Once I have made the ARP entry into a static binding it is no more intermittent.
This issue persists in both huawei and cisco switch environment and I believe this is related to MikroTik CHR. Pleas share if you face similar issues in CHR environment.
