Enables blackholing of packets during ACL (Access Control List) refresh.
This command has no arguments or variables.
Enabled.
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
The following command enables dropping of packets during an ACL refresh:
enable access-list refresh blackhole
This command was first available in ExtremeXOS 11.0.
