Description

Configure RADIUS for 802.1x authentication using a fully-qualified domain name (FQDN). Use an FQDN if the server name can translate to more than one address. The FQDN resolves dynamically at regular intervals so there is no need to modify the configuration for address changes.

The FQDN is first resolved at the time of configuration commit, and then at fixed intervals based on the configured value for the dns-query-interval statement.

You can combine the FQDN configuration with the round-robin algorithm to achieve load distribution among the available servers. Configure the round-robin algorithm at the [edit access profile profile-name radius options] hierarchy level.

To configure a RADIUS server using a fixed IP address, use the radius-server statement.

Options

hostname

Configure the FQDN to identify the RADIUS server. The hostname parameter supports only one FQDN. To configure more than one FQDN, use multiple radius-server-name statements.

dns-query-interval

Configure the interval for resolving an FQDN as the server address. The FQDN is resolved dynamically at fixed intervals based on the configured value.

  • Values: minutes—Interval of the FQDN resolution in minutes.
  • Range: 10 through 1440
  • Default: 60

The remaining statements are explained separately. Search for a statement in CLI Explorer or click a linked statement in the Syntax section for details.

Required Privilege Level

system—To view this statement in the configuration.

system-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 21.1R1.
