6, 7, and 8 and are assigned to the hardware egress queue 0, which is the default queue. All
other traffic is explicitly denied on these interfaces. To allow additional traffic to enter these
ports, you must add a new permit rule with the desired match criteria and bind the rule to
interfaces 6, 7, and 8.

Standard IP ACL Example Configuration

The following example shows how to create an IP-based ACL that prevents any IP traffic
from the Finance department from being allowed on the ports that are associated with other
departments. Traffic from the Finance department is identified by each packet's network IP
address.
1. From the IP ACL screen, create a new IP ACL with an IP ACL ID of 1 (See
page 6-531).
2. From the IP Rules screen, create a rule for IP ACL 1 with the following settings:
• Rule ID: 1
• Action: Deny
• Assign Queue ID: 0 (optional: 0 is the default value)
• Match Every: False
• Source IP Address: 192.168.187.0
• Source IP Mask: 255.255.255.0
For additional information about IP ACL rules, see
3. Click Add.
4. From the IP Rules screen, create a second rule for IP ACL 1 with the following settings:
• Rule ID: 2
• Action: Permit
• Match Every: True
5. Click Add.
6. From the IP Binding Configuration page, assign ACL ID 1 to the interface gigabit ports 2, 3,
and 4, and assign a sequence number of 1 (See
By default, this IP ACL is bound on the inbound direction, so it examines traffic as it
enters the switch.
7. Click Apply.
8. Use the IP Binding Table screen to view the interfaces and IP ACL binding information (See
"IP Binding Table" on page
The IP ACL in this example matches all packets with the source IP address and subnet mask
of the Finance department's network and deny it on the Ethernet interfaces 2, 3, and 4 of the
switch. The second rule permits all non-Finance traffic on the ports. The second rule is
required because there is an explicit deny all rule as the lowest priority rule.
