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 1:1 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.
