Usage Guidelines
When access control lists (ACLs) are refreshed, this feature 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.
If you disable this feature, you may get unexpected results as the ACL is refreshed.
To enable this feature, use the following command:
enable access-list refresh blackhole
Example
The following command disables dropping of packets during an ACL refresh:
