Chapter 11 Configuring Web-Based Authentication
Configuring Web-Based Authentication
Hosts that are more than one hop away might experience traffic disruption if an STP t opology
change results in the host traffic arriving on a different port. This occurs because the ARP and DHCP
updates might not be sent after a Layer 2 (STP) topology change.
Web-based authentication does not support VLAN assignment as a downloadable-host policy.
Web-based authentication is not supported for IPv6 traffic.

Configuring the Authentication Rule and Interfaces
This example shows how to enable web-based authentication on Fast Ethernet port 5/1:
Switch(config)# ip admission name webauth1 proxy http
Switch(config)# interface fastethernet 5/1
Switch(config-if)# ip admission webauth1
Switch(config-if)# exit
Switch(config)# ip device tracking
Command Purpose
Step 1 ip admission name name proxy http Configure an authentication rule for web-based authorization.
Step 2 interface type slot/port Enter interface configuration mode and specifies the ingress Layer 2 or
Layer 3 interface to be enabled for web-based authenti cation.
type can be fastethernet, gigabit ethernet, or tengigabitethernet.
Step 3 ip access-group name Apply the default ACL.
Step 4 ip admission name Configures web-based authentication on the specified interface.
Step 5 exit Return to configuration mode.
Step 6 ip device tracking Enables the IP device tracking table.
Step 7 end Return to privileged EXEC mode.
Step 8 show ip admission configuration Display the configuration.
Step 9 copy running-config startup-config (Optional) Save your entries in the configuration file.
