Access Control Lists

The following restrictions apply to ACLs:

The maximum number of ACLs is 128.

The maximum number of rules per system is 512 rules.

An ACL can have up to 64 rules. However, due to resource restrictions,

the average number of rules bound to the ports should not exceed 20.

The order in which active ACLs are checked is as follows:

User-defined rules in IP and MAC ACLs for ingress ports are checked in

Rules within an ACL are checked in the configured order, from top to

If the result of checking an IP ACL is to permit a packet, but the result

of a MAC ACL on the same packet is to deny it, the packet will be

denied (because the decision to deny a packet has a higher priority for

security reasons). A packet will also be denied if the IP ACL denies it

and the MAC ACL accepts it.

during which ACL functions are applied.
