Due to a chipset limitation, the switch currently supports a
maximum of ten access profiles, each containing a maximum of
50 rules
−
with the additional limitation of 50 rules total for all
ten access profiles.
Access profiles allow you to establish criteria to determine
whether 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, and specify
deny
:
create access_profile ip source_ip_mask 255.255.255.0 deny
profile_id 1
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,
