RADIUS
The nv unset commands remove the configuration you set with the equivalent nv set commands. This guide only describes an nv unset command if it differs from the nv set command.

Command Syntax
| Syntax | Description |
|---|---|
<hostname-id> | The IP address or hostname of the RADIUS server. |

cumulus@switch:~$ nv set system aaa radius server 192.168.0.254 timeout 10
nv set system aaa radius debug
Configures the debug option for troubleshooting. The debugging messages write to /var/log/syslog. When the RADIUS client is working correctly, you can disable the debug option. You can specify enable or disable.
Version History
Introduced in Cumulus Linux 5.7.0
Example
cumulus@switch:~$ nv set system aaa radius debug enable
nv set system aaa radius enable
Enables (on) and disables (off) RADIUS.
Version History
Introduced in Cumulus Linux 5.7.0
Example
cumulus@switch:~$ nv set system aaa radius enable on
nv set system aaa radius port
Configures the port you want to use for all RADIUS communication. You can specify a value between 0 and 65535. The default value is 1812.
nv set system aaa radius privilege-level
Configures the minimum privilege level that determines if users can configure the switch with NVUE commands and sudo, or have read-only rights. The default privilege level is 15, which provides full administrator access. This is a global option only; you cannot set the minimum privilege level for specific RADIUS servers.
Version History
Introduced in Cumulus Linux 5.7.0
Example
cumulus@switch:~$ nv set system aaa radius privilege-level 10
nv set system aaa radius retransmit
Configures the maximum number of retransmission attempts allowed for requests when a RADIUS authentication request times out. This is a global option only; you cannot set the number of retransmission attempts for specific RADIUS servers.
