Idle TimeEvery session line has its own idle-time. If the idle-time value is not changed, the default value of 30 minutes is used.RADIUS specifies idle-time allow for a user during a session before timeout. When a user logs in, the lower of the two idle-time values(configured or default) is used. The idle-time value is updated if both of the following happens:• The administrator changes the idle-time of the line on which the user has logged in.• The idle-time is lower than the RADIUS-returned idle-time.ACL Configuration InformationThe RADIUS server can specify an ACL. If an ACL is configured on the RADIUS server, and if that ACL is present, the user may be allowedaccess based on that ACL.If the ACL is absent, authorization fails, and a message is logged indicating this.RADIUS can specify an ACL for the user if both of the following are true:• If an ACL is absent.• If there is a very long delay for an entry, or a denied entry because of an ACL, and a message is logged.NOTE: The ACL name must be a string. Only standard ACLs in authorization (both RADIUS and TACACS) are supported.Authorization is denied in cases using Extended ACLs.Auto-CommandYou can configure the system through the RADIUS server to automatically execute a command when you connect to a specific line.The auto-command command is executed when the user is authenticated and before the prompt appears to the user.• Automatically execute a command.auto-commandPrivilege LevelsThrough the RADIUS server, you can configure a privilege level for the user to enter into when they connect to a session.This value is configured on the client system.• Set a privilege level.privilege levelConfiguration Task List for RADIUSTo authenticate users using RADIUS, you must specify at least one RADIUS server so that the system can communicate with and configureRADIUS as one of your authentication methods.The following list includes the configuration tasks for RADIUS.• Defining a AAA Method List to be Used for RADIUS (mandatory)• Applying the Method List to Terminal Lines (mandatory except when using default lists)• Specifying a RADIUS Server Host (mandatory)• Setting Global Communication Parameters for all RADIUS Server Hosts (optional)766 Security
