S3300 Smart Switch
The ACL named Sales_ACL looks for Ethernet frames with destination and source MAC
addresses and MAC masks defined in the rule. Also, the frame must be tagged with VLAN ID
2, which is the Sales department VLAN. The CoS value of the frame must be 0, which is the
default value for Ethernet frames. Frames that match this criteria are permitted on interfaces
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 Configuration Example
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.
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.
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
3.
Click the Add button.
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 the Add button.
6.
From the IP Binding Configuration screen, assign ACL ID 1 to the Ethernet ports 2, 3, and 4,
and assign a sequence number of 1.
and assign a sequence number of 1.
By default, this IP ACL is bound on the inbound direction, so it examines traffic as it
enters the switch.

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
