Requirements for using ACL logging

  • The switch configuration must include an ACL assigned to a port, trunk, or static VLAN interface. This ACL must contain an ACE configured with the deny action and the log option.

  • If the RACL application is used, then IPv4 routing must be enabled on the switch.

  • For ACL logging to a Syslog server:
    • The server must be accessible to the switch and identified in the running configuration.

    • The logging facility must be enabled for Syslog.

    • Debug must be configured to:
      • support ACL messages

      • send debug messages to the desired debug destination

These requirements are described in more detail under Enabling ACL logging on the switch.
