Remote AAA RADIUS server configuration requirements

The user-supplied RADIUS server must:
  • Have an IPv4/IPv6 address or fully qualified domain name (FQDN) that is visible to the switch.

  • Have a passkey (shared secret) that matches what is configured on the switch.

  • Provide username and password definitions for every switch user. Remote users do not require definition on the switch.

  • Use the Service-Type RADIUS attribute with the following values (as defined in RFC 2865):

    • 7 (NAS-Prompt): for users requiring the Operators role.

    • 6 (Administrative): for users requiring the Administrators role.

    • Any other Service-Type value results in the user being denied access.

NOTE:

Consult your RADIUS server documentation for installation and general configuration details.

NOTE:

If SSH public key authentication is used, the key information is stored locally on the switch, making username and password definition on the RADIUS server unnecessary.
