The shared secret is a password that is configured on each network device (RADIUS client) and RADIUS accounting server. The shared secret is used to verify communication between network devices and the server.
To configure the primary RADIUS accounting server, specify primary. To configure the secondary RADIUS accounting server, specify secondary.
If you do not specify the mgmt-access or netlogin keywords, the secret applies to both the primary and secondary switch management and network login RADIUS accounting servers.
Do not use the encrypted keyword to set the shared secret. The encrypted keyword prevents the display of the shared secret in the show configuration command output.
