Note: The configuration of Free Radius is done on Ubuntu(Linux) Server. Restart the Radius service, Now when you login to the device, User will get the level 3 privilege. User Based Privilege:If you want that user in the FreeRadius server should login and get level 3 privilege:Įdit /etc/freeradius/users file: sudo nano/etc/freeradius/usersĪdd another user "Life" with a privilege level of 3 Life Cleartext-Password := "testing" Service-Type = NAS-Prompt-User, Push the below role, The user in the IOS will get the level 15 Privilege.This would be applicable for all the users who are member of group cisco-rw DEFAULT Group = cisco-rw, Auth-Type = System, Service-Type = NAS-Prompt-User, cisco-avpair :="shell:priv-lvl=15"Īfter pushing the shell lvl 15, The user will get the privi level 15 access.

Create a local user on the switch with full privileges for fallback with the username command as shown here Switch(config)#username admin privilege 15 password 0 cisco123!Ģ. Switch Configuration - Authentication and Authorizationġ. PrerequisitesĮnsure that you have your Cisco switch defined as a client in free radius with the ip address and same shared secret key defined on the free radius and switch Components Used By adding authorization exec, we can bypass enable authentication and directly land the user to privilege 15 mode.
