Description: Counter of DHCP packets dropped by CPU due to no associated Traffic IP Interface found.

What is cmEthernetTrafficPortStatsDhcpDropNoAssocIf?

This counter records the number of DHCP packets dropped on this port by the CPU because no associated Traffic IP Interface could be found for them. A rising count tells the admin that DHCP requests are arriving on this port but can't be mapped to a configured IP interface, meaning affected subscribers will fail to obtain an address. For example, if a newly provisioned customer can't get a DHCP lease, the admin would check cmEthernetTrafficPortStatsDhcpDropNoAssocIf on that port to see if the request is being dropped for lack of a matching Traffic IP Interface.
