N-series and ACL Hardware Limitation


Hardware Limitation with ACLs on N-series and following with a true example:

Customer encountered the error listed below while adding access list.

"Error encountered applying ACL to HW. HW limit may have been exceeded."

It is not an error. The N-Series switches have the following ACL software limits:

For additional information on ACL limitations, see the User’s Configuration Guide by visting the Dell Support Site.

Port ranges (highlighted in RED) are NOT supported on egress (out) interfaces. The only port operator supported on egress is the "eq" operator. This is a HW limitation and cannot be "fixed" via SW fix.
