cmFlowPointHistoryAclDropNoMatch
Module: CM-PERFORMANCE-MIB
OID (symbolic): CM-PERFORMANCE-MIB::cmFlowPointHistoryAclDropNoMatch
OID (numeric): 1.3.6.1.4.1.2544.1.12.5.1.26.1.37
Node type: OBJECT-TYPE
Type: PerfCounter64
Access: read-only
Description: The number of dropped packets due to no match in ACL rule.
What is cmFlowPointHistoryAclDropNoMatch?
This read-only PerfCounter64 counts packets dropped at this flow point because they matched no rule in the applicable ACL, implying a default-deny policy took effect. It helps an administrator distinguish traffic silently rejected by a catch-all deny from traffic explicitly blocked by a specific rule, which changes the troubleshooting approach. For example, a customer reporting a new application can't reach the network would prompt a check of cmFlowPointHistoryAclDropNoMatch to see if its traffic is simply falling through to the default deny because no permit rule was added.
