CLI – This example shows how to create an Ingress MAC ACL and bind
it to a port. You can then see that the order of the rules have been changed
by the mask.
Binding a Port to an Access Control List
After configuring the Access Control Lists (ACL), you can bind the ports
that need to filter traffic to the appropriate ACLs. You can only bind a port
to one ACL for each basic type – IP ingress, IP egress, MAC ingress and
MAC egress.
Command Usage
• This switch supports ACLs for both ingress and egress filtering.
However, you can only bind one IP ACL and one MAC ACL to any
port for ingress filtering, and one IP ACL and one MAC ACL to any
port for egress filtering. In other words, only four ACLs can be bound
to an interface – Ingress IP ACL, Egress IP ACL, Ingress MAC ACL
and Egress MAC ACL.
• When an ACL is bound to an interface as an egress filter, all entries in
the ACL must be deny rules. Otherwise, the bind operation will fail.
