Usage Guidelines
When access control lists (ACLs) are refreshed, this command provides that any packets arriving during
the refresh will be blackholed. As the ACL is being refreshed, packets may arrive while the ACL is in an
indeterminate state, and packets may be permitted that otherwise are dropped. This feature protects the
switch during an ACL refresh. To disable this feature, use the following command:
disable access-list refresh blackhole
Example
The following command enables dropping of packets during an ACL refresh:
