Chapter 44 Configuring 802.1X Port-Based Authentication
Configuring 802.1X Port-Based Authentication
When CISP is enabled on a trunk port, the following features are inert. When CISP is neither running
nor configured, these features operate as expected:
• VLAN assignment
• Guest, Authentication Failure, voice, and critical VLANs
• Critical authentication
• Wake-on-LAN
• Web authentication
• Port security
• Violation modes (restrict, shut down, and shut down VLAN)
The following example shows how to enable CISP on a port. You must configure the following procedure
in the Cisco ACS server. Configuring a user with Cisco AV Pair value, allows SSW to authenticate itself
with the ASW. Because the user is attached with the AV pair value, upon successful authentication on
ASW, the macro is executed on the interface on which SSW is authenticated:
Switch# configure terminal
Switch(config)# cisp enable
Switch(config)# interface GigabitEthernet5/23
Switch(config-if)# switchport mode access
Switch(config-if)# spanning-tree portfast
Switch(config-if)# dot1x pae authenticator
Switch(config-if)# authentication port-control auto
Cisco AV Pair Configuration
Next, you need to configure a Cisco AV pair value.
Log into ACS, and Select/Create a User. Go to User Setup and scroll down to the [009\001]
cisco-av-pair Tab. Enter device-traffic-class=switch (Figure 44-17).
