Configuring a MAC ACL Mask - Web
Configure the mask to match the required rules in the MAC ingress or egress ACLs. Set the mask to check for
any source or destination address, a host address, or an address range.
Use a bitmask to search for specific VLAN ID(s) or Ethernet type(s). Or check for rules where a packet format
was specified. Then click Add.
Configuring a MAC ACL Mask - 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 - Web
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.
