X Authentication With Downloadable Acls And Redirect Urls - Cisco 3032 Software Configuration Manual

Understanding IEEE 802.1x Port-Based Authentication
RADIUS supports per-user attributes, including vendor-specific attributes. These vendor-specific
attributes (VSAs) are in octet-string format and are passed to the switch during the authentication
process. The VSAs used for per-user ACLs are
the egress direction. MAC ACLs are supported only in the ingress direction. The switch supports VSAs
only in the ingress direction. It does not support port ACLs in the egress direction on Layer 2 ports. For
more information, see
Use only the extended ACL syntax style to define the per-user configuration stored on the RADIUS
server. When the definitions are passed from the RADIUS server, they are created by using the extended
naming convention. However, if you use the Filter-Id attribute, it can point to a standard ACL.
You can use the Filter-Id attribute to specify an inbound or outbound ACL that is already configured on
the switch. The attribute contains the ACL number followed by .in for ingress filtering or .out for egress
filtering. If the RADIUS server does not allow the .in or .out syntax, the access list is applied to the
outbound ACL by default. Because of limited support of Cisco IOS access lists on the switch, the
Filter-Id attribute is supported only for IP ACLs numbered 1 to 199 and 1300 to 2699 (IP standard and
IP extended ACLs).
Per-user ACLs are supported only in single-host mode.
The maximum size of the per-user ACL is 4000 ASCII characters but is limited by the maximum size of
RADIUS-server per-user ACLs.
For examples of vendor-specific attributes, see the

802.1x Authentication with Downloadable ACLs and Redirect URLs

You can download ACLs and redirect URLs from a RADIUS server to the switch during 802.1x
authentication or MAC authentication bypass of the host. You can also download ACLs during web
authentication.
Note A downloadable ACL is also referred to as a dACL.
If the host mode is single-host, MDA, or multiple-authentication mode, the switch modifies the source
address of the ACL to be the host IP address.
You can apply the ACLs and redirect URLs to all the devices connected to the 802.1x-enabled port.
