20radius-scheme radius-scheme-name: Specifies a RADIUS scheme by its name, a case-insensitivestring of 1 to 32 characters.Usage guidelinesYou can specify one primary authentication method and multiple backup authentication methods.When the primary method is invalid, the device attempts to use the backup methods in sequence.For example, the authentication ipoe radius-scheme radius-scheme-name local none commandspecifies a primary RADIUS authentication method and two backup methods (local authenticationand no authentication). The device performs RADIUS authentication by default and performs localauthentication when the RADIUS server is invalid. The device does not perform authentication whenboth of the previous methods are invalid.Examples# In ISP domain test, perform local authentication for IPoE users. system-view[Sysname] domain test[Sysname-isp-test] authentication ipoe local# In ISP domain test, perform RADIUS authentication for IPoE users based on scheme rd and uselocal authentication as the backup. system-view[Sysname] domain test[Sysname-isp-test] authentication ipoe radius-scheme rd localRelated commandsauthentication defaultlocal-userradius schemeauthentication lan-accessUse authentication lan-access to specify authentication methods for LAN users.Use undo authentication lan-access to restore the default.SyntaxIn non-FIPS mode:authentication lan-access { ldap-scheme ldap-scheme-name [ local ] [ none ] | local [ none ] |none | radius-scheme radius-scheme-name [ local ] [ none ] }undo authentication lan-accessIn FIPS mode:authentication lan-access { ldap-scheme ldap-scheme-name [ local ] | local | radius-schemeradius-scheme-name [ local ] }undo authentication lan-accessDefaultThe default authentication methods of the ISP domain are used for LAN users.ViewsISP domain viewPredefined user rolesnetwork-admin
