Mapping Security ACLs 391
To map a security ACL to a user session, follow these steps:
1 Create the security ACL. For example, to filter packets coming from
192.168.253.1 and going to 192.168.253.12, type the following:
WX1200# set security acl ip acl-222 permit
ip 192.168.253.1 0.0.0.0 198.168.253.12 0.0.0.0
hits
2 Commit the security ACL to the running configuration. For example, to
commit acl-222, type the following command:
WX1200# commit security acl acl-222
success: change accepted.
3 Apply the Filter-Id authentication attribute to a user’s session via an
external RADIUS server. For instructions, see the documentation for your
RADIUS server.
If the Filter-Id value returned through the authentication and
authorization process does not match the name of a committed security
ACL in the WX, the user fails authorization and cannot be authenticated.
4 Alternatively, authenticate the user with the Filter-Id attribute in the WX
switch’s local database. Use one of the commands shown in Table 33.
Specify .in for incoming packets or .out for outgoing packets.
When assigned the Filter-Id attribute, an authenticated user with a
current session receives packets based on the security ACL. For example,
to restrict incoming packets for Natasha to those specified in acl-222,
type the following command:
WX1200# set user Natasha attr filter-id acl-222.in
success: change accepted.
You can also map a security ACL to a user group. For details, see
“Assigning a Security ACL to a User or a Group” on page 494. For more
information about authenticating and authorizing users, see “About
Administrative Access” on page 54 and “AAA Tools for Network Users”
on page 441.
