Description: Counter of DHCP packets dropped by CPU due to no associated Traffic IP Interface found.
What is cmEthernetTrafficPortHistoryDhcpDropNoAssocIf?
This counter records the number of DHCP packets dropped on this port during the archived historical interval because no associated Traffic IP Interface could be found. A historical review lets the admin date exactly when a subscriber's DHCP requests began failing due to a missing interface association, useful for a provisioning-ticket investigation. For example, if a customer says they couldn't get online since yesterday, the admin would check cmEthernetTrafficPortHistoryDhcpDropNoAssocIf from around that time to confirm DHCP was being dropped on their port.
