disable access-list permit to-cpu

disable access-list permit to-cpu


Allows special packets to be blocked by low priority ACLs.

Syntax Description

This command has no arguments or variables.



Usage Guidelines

This command allows ACLs to deny certain special packets from reaching the CPU, even if the packets match ACLs that would otherwise deny them. The special packets include STP and EAPS BPDUs, and ARP replies for the switch.

When this feature is disabled, these same packets will be denied if an ACL is applied that contains a matching entry that denies the packets. Contrary to expectations, the packets will still be denied if there is a higher precedence entry that permits the packets.

To enable this feature, use the following command:

enable access-list permit to-cpu


The following example enables ACLs to deny STP BPDU packets from reaching the switch CPU:

disable access-list permit to-cpu


This command was first available in ExtremeXOS 11.3.2.
