MAC ACL
A MAC ACL consists of a set of rules which are matched sequentially against a packet. When
a packet meets the match criteria of a rule, the specified rule action (Permit/Deny) is taken
and the additional rules are not checked for a match.
There are multiple steps involved in defining a MAC ACL and applying it to the switch:
1. Use the MAC ACL page to create the ACL ID.
2. Use t
he MAC Rules page to create rules for the ACL.
3. Use t
he MAC Binding Configuration page to assign the ACL by its ID number to a port.
4. Option
ally, use the MAC Binding Table page to view the configurations.
To display the MAC ACL page, click Sec
urity  ACL. The MAC ACL page is under the Basic
link.
The MAC ACL table displays the number of ACLs currently configured in the switch and the
maximum number of ACLs that can be configured. The current size is equal to the number of
configured IPv4 ACLs plus the number of configured MAC ACLs.
To configure a MAC ACL:
1. T
o add a MAC ACL, specify a name for the MAC ACL in the Name field, and click Add.
The name string may include alphabetic, numeric, dash, underscore, or space
characters only. The name must start with an alphabetic character.
Each configured ACL displays the following information:
• Rules. Displays the nu
mber of rules currently configured for the MAC ACL.
• Dir
ection. Displays the direction of packet traffic affected by the MAC ACL, which can
be Inbound or blank.
