## Adding Configuration Statements and Identifiers

When you use the ? help to view a list of possible command completions, the output includes symbols that provide more information about the statement. The following symbols can appear in a list:

- Angle bracket ( > ) before the statement name indicates that the statement is a container statement and that you can define other statements at levels below it.
- No angle bracket ( > ) before the statement name indicates that the statement is a leaf statement; you cannot define other statements at hierarchy levels below it.
- Plus sign (+) before the statement name indicates that the statement can contain a set of values. To specify a set, include the values in brackets.
- Asterisk (*) before a statement name indicates a required statement or option that is not configured.
- Plus/Asterisk (+*) before a statement name indicates a required option that can contain a set of values.

The following example at the [edit system services] hierarchy level shows that authentication-order, domain-search, and name-server can contain more than one value.

    [edit system]
    user@host# show ?
    Possible completions:
      <[Enter]>            Execute this command
    + authentication-order Order in which authentication methods are invoked
    + domain-search        List of domain names to search
      host-name            Hostname for C Series Controller
    > ldap                 LDAP properties
    > login                Login properties
    + name-server          DNS name servers
    > ntp                  NTP configuration
    > radius-server        RADIUS server configuration
    > services             System services configuration
    > syslog               System log configuration
    > tacplus-server       TACACS+ server configuration
      time-zone            Time zone definition name
      |                    Pipe through a command

The following example at the [edit shared sae configuration driver] hierarchy level shows that mac-cache-expiration and unauthenticated-subscriber-dn are required statements.

    [edit shared sae configuration driver]
    user@host#  show ?
    Possible completions:
      <[Enter]>            Execute this command
    > junos                Parameters the SAE uses to manage JUNOS routing platforms
    > junose               Parameters the SAE uses to manage JUNOSe routers
    * mac-cache-expiration Time that a subscriber profile remains in SAE cache (0..I
    NF s)
    > pcmm                 Parameters that SAE uses to manage PCMM devices
    > scripts              Scripts to customize setup of SAE connections to devices
    > simulated            Parameters that the SAE uses for simulated drivers
    > snmp                 Global default SNMP communities
    > third-party          Parameters that SAE uses to manage third-party devices
    * unauthenticated-subscriber-dn
                           DN of an unauthenticated subscriber profile
      virtual-portal-address
                           IP address of the portal server
      |                    Pipe through a command

If you do not type an option for a statement that requires one, a message indicates the type of information expected. In this example, you need to type an area number as an identifier to complete the logger name:

    [edit]
    user@host# set shared sae configuration logger
                                                    ^
    syntax error, expecting <identifier>.
