Cisco Systems 3560 Manual De Usuario

If a downloadable ACL or redirect URL is configured for a client on the authentication server, a default 
port ACL on the connected client switch port must also be configured.

The switch uses these cisco-av-pair VSAs:

url-redirect is the HTTP to HTTPS URL.

url-redirect-acl is the switch ACL name or number.

The switch uses the CiscoSecure-Defined-ACL AV pair to intercept an HTTP or HTTPS request from 
the endpoint device. The switch then forwards the client web browser to the specified redirect address. 
The url-redirect AV pair on the Cisco Secure ACS contains the URL to which the web browser is 
redirected. The url-redirect-acl AV pair contains the name or number of an ACL that specifies the HTTP 
or HTTPS traffic to redirect. Traffic that matches a permit ACE in the ACL is redirected.

Define the URL redirect ACL and the default port ACL on the switch.

If a redirect URL configured for a client on the authentication server, a default port ACL on the 
connected client switch port must also be configured

You can set the CiscoSecure-Defined-ACL Attribute-Value (AV) pair on the Cisco Secure ACS with the 
RADIUS cisco-av-pair vendor-specific attributes (VSAs). This pair specifies the names of the 
downloadable ACLs on the Cisco Secure ACS with the #ACL#-IP-name-number attribute.

The name is the ACL name.

The number is the version number (for example, 3f783768).

If a downloadable ACL is configured for a client on the authentication server, a default port ACL on the 
connected client switch port must also be configured.

If the default ACL is configured on the switch and the Cisco Secure ACS sends a host-access-policy to 
the switch, it applies the policy to traffic from the host connected to a switch port. If the policy does not 
apply, the switch applies the default ACL. If the Cisco Secure ACS sends the switch a downloadable 
ACL, this ACL takes precedence over the default ACL that is configured on the switch port. However, 
if the switch receives an host access policy from the Cisco Secure ACS but the default ACL is not 
configured, the authorization failure is declared.

You can configure a guest VLAN for each 802.1x port on the switch to provide limited services to 
clients, such as downloading the 802.1x client. These clients might be upgrading their system for 802.1x 
authentication, and some hosts, such as Windows 98 systems, might not be  802.1x-capable.
