What Are Mac Acls - Dell Networking 7048 Configuration Manual

Depending on whether an ingress or egress ACL is applied to a port, when the
traffic enters (ingress) or leaves (egress) a port, the ACL compares the criteria
configured in its rules, in order, to the fields in a packet or frame to check for
matching conditions. The ACL forwards or blocks the traffic based on the
rules.
NOTE:
Every ACL is terminated by an implicit deny all rule, which covers any
packet not matching a preceding explicit rule.
You can set up ACLs to control traffic at Layer 2, Layer 3, or Layer 4. MAC
ACLs operate on Layer 2. IP ACLs operate on Layers 3 and 4. PowerConnect
7000 Series switches support both IPv4 and IPv6 ACLs.

What Are MAC ACLs?

MAC ACLs are Layer 2 ACLs. You can configure the rules to inspect the
following fields of a packet:
• Source MAC address
• Source MAC mask
• Destination MAC address
• Destination MAC mask
• VLAN ID
• Class of Service (CoS) (802.1p)
• EtherType
L2 ACLs can apply to one or more interfaces.
Multiple access lists can be applied to a single interface; sequence number
determines the order of execution.
You can assign packets to queues using the assign queue option.
