The following screen displays:
2. From the ACL Name field, specify the existing MAC ACL to which the rule applies.
For information about how to set up a new MAC ACL, use the
3. In the ID field, enter an ID for the rule.
The valid range is 1-10.
4. Configure the following settings:
• Action. Specify what action must be taken if a packet matches the rule's criteria.
• Permit. Forwards packets that meet the ACL criteria.
• Deny. Drops packets that meet the ACL criteria.
• Match Every. Requires a packet to match the criteria of this ACL. Select Enable or
Disable. Match Every is exclusive to the other filtering rules, so if Match Every is
True, the other rules on the screen are not available.
• CoS. Requires a packet's Class of Service (CoS) to match the CoS value listed here.
Enter a CoS value between 0–7 to apply this criteria.
• Destination MAC. Requires an Ethernet frame's destination port MAC address to
match the address listed here. Enter a MAC address in this field. The valid format is
xx:xx:xx:xx:xx:xx.
• Destination MAC Mask. If desired, enter the MAC mask associated with the
destination MAC to match. The MAC address mask specifies which bits in the
destination MAC to compare against an Ethernet frame. Use Fs and 0s in the MAC
mask, which is in a wildcard format. An F means that the bit is not checked, and a 0 in
a bit position means that the data must equal the value given for that bit. For example,
if the MAC address is aa:bb:cc:dd:ee:ff, and the mask is 00:00:ff:ff:ff:ff, all MAC
addresses with aa:bb:xx:xx:xx:xx result in a match (where x is any hexadecimal
number). A MAC mask of 00:00:00:00:00:00 matches a single MAC address.
