Requirements for using ACL logging

• The switch configuration must include an ACL (1) assigned to a port, trunk, or static VLAN interface and (2) containing an ACE configured with the deny or permit action and the log option.

• For ACL logging to a 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 in Enabling ACL logging on the switch.
