ACCESS CONTROL LIST (ACL) COMMANDS

The Switch implements Access Control Lists that enable the Switch to deny network access to specific devices or device

groups based on IP settings and MAC address. Access profiles allow you to establish criteria to determine whether or not

the Switch will forward packets based on the information contained in each packet’s header. These criteria can be

specified on a VLAN-by-VLAN basis.

Creating an access profile is divided into two basic parts. First, an access profile must be created using the create

access_profile command. For example, if you want to deny all traffic to the subnet 10.42.73.0 to 10.42.73.255, you must

first create an access profile that instructs the Switch to examine all of the relevant fields of each frame:

create access_profile profile_id 1 ip source_ip_mask 255.255.255.0

Here we have created an access profile that will examine the IP field of each frame received by the Switch. Each source

IP address the Switch finds will be combined with the source_ip_mask with a logical AND operation. The profile_id

parameter is used to give the access profile an identifying number

−

in this case, 1. The deny parameter instructs the

Switch to filter any frames that meet the criteria

−

in this case, when a logical AND operation between an IP address

specified in the next step and the ip_source_mask match.

The default for an access profile on the Switch is to permit traffic flow. If you want to restrict traffic, you must use the deny

parameter.

Now that an access profile has been created, you must add the criteria the Switch will use to decide if a given frame

should be forwarded or filtered. Here, we want to filter any packets that have an IP source address between 10.42.73.0

and 10.42.73.255:

config access_profile profile_id 1 add access_id 1 ip source_ip 10.42.73.1 port 1 deny

Here we use the profile_id 1 which was specified when the access profile was created. The add parameter instructs the

Switch to add the criteria that follows to the list of rules that are associated with access profile 1. For each rule entered

into the access profile, you can assign an access_id that both identifies the rule and establishes a priority within the list of

rules. A lower access_id gives the rule a higher priority. In case of a conflict in the rules entered for an access profile, the

rule with the highest priority (lowest access_id) will take precedence.

The ip parameter instructs the Switch that this new rule will be applied to the IP addresses contained within each frame’s

header. source_ip tells the Switch that this rule will apply to the source IP addresses in each frame’s header. Finally, the

IP address 10.42.73.1 will be combined with the source_ip_mask 255.255.255.0 to give the IP address 10.42.73.0 for any

source IP address between 10.42.73.0 to 10.42.73.255.

Due to a chipset limitation, the Switch supports a maximum of fourteen access profiles. The rules used to define the

access profiles are limited to a total of 1792 rules for the Switch. One rule can support ACL per port or per portmap.
