Chapter 1 Configuring Switch-Based Authentication
Controlling Switch Access with RADIUS
To disable AAA, use the no aaa new-model global configuration command. To disable the AAA server
functionality on the switch, use the no aaa server radius dynamic authorization global configuration
command.
Monitoring and Troubleshooting CoA Functionality
The following Cisco IOS commands can be used to monitor and troubleshoot CoA functionality on the
switch:
• debug radius
• debug aaa coa
• debug aaa pod
• debug aaa subsys
• debug cmdhd [detail | error | events]
• show aaa attributes protocol radius
Step 4
client {ip-address | name} [vrf vrfname]
[server-key string]
Enter dynamic authorization local server configuration mode and specify
a RADIUS client from which a device will accept CoA and disconnect
requests.
Step 5
server-key [0 | 7] string Configure the RADIUS key to be shared between a device and RADIUS
clients.
Step 6
port port-number Specify the port on which a device listens for RADIUS requests from
configured RADIUS clients.
Step 7
auth-type {any | all | session-key} Specify the type of authorization the switch uses for RADIUS clients.
The client must match all the configured attributes for authorization.
Step 8
ignore session-key (Optional) Configure the switch to ignore the session-key.
For more information about the ignore command, see the Cisco IOS
Intelligent Services Gateway Command Reference on Cisco.com.
Step 9
ignore server-key (Optional) Configure the switch to ignore the server-key.
For more information about the ignore command, see the Cisco IOS
Intelligent Services Gateway Command Reference on Cisco.com.
Step 10
authentication command bounce-port
ignore
(Optional) Configure the switch to ignore a CoA request to temporarily
disable the port hosting a session. The purpose of temporarily disabling
the port is to trigger a DHCP renegotiation from the host when a VLAN
change occurs and there is no supplicant on the endpoint to detect the
change.
Step 11
authentication command disable-port
ignore
(Optional) Configure the switch to ignore a nonstandard command
requesting that the port hosting a session be administratively shut down.
Shutting down the port results in termination of the session.
Use standard CLI or SNMP commands to re-enable the port.
Step 12
end Return to privileged EXEC mode.
Step 13
show running-config Verify your entries.
Step 14
copy running-config startup-config (Optional) Save your entries in the configuration file.
