Which mnemonic in Cisco IOS logs indicates a packet matching the log criteria for a given access list?

The mnemonic %SEC-6-IPACCESSLOGP in Cisco IOS logs specifically indicates that a packet has successfully matched the criteria defined in an access list. This log message is part of the security logging system that informs administrators about events related to network access, providing visibility into which packets were allowed or denied based on access control rules.

In the context of network security, monitoring access lists is crucial, as they control the flow of traffic into and out of network interfaces. When a packet matches the conditions set by an access list, generating this log helps system administrators audit and analyze network traffic, providing insights for security assessments and troubleshooting.

The numerical level associated with this particular mnemonic (6) denotes the severity of the message, indicating that the logged event is informational and does not inherently signal an error or failure. This contrasts with other mnemonics that represent more severe or error-based conditions, providing a clearer understanding of the network's state and traffic patterns.
