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 should bind them
to the ports that need to filter traffic. You can only bind a port to one ACL
for each basic type – IP ingress, IP egress, MAC ingress and MAC egress.
Command Usage
• You must configure a mask for an ACL rule before you can bind it to
a port.
• 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.
