What is accDhcpSrvRefusals?
This OID counts how many DHCP client requests were denied by the server, usually due to the pool being exhausted or a client being blacklisted. Administrators watch this counter to identify pool capacity problems or unauthorized access attempts that the server is blocking. For example, if refusals spike to 234 over one hour when they're normally near zero, it suggests either a surge in legitimate client activity exceeding pool size or a misconfiguration.
