• The [ and ] symbols denote an optional feature. Features enclosed by these
symbols are not essential for execution of the command, although omitting such
features might adversely affect the outcome.
• The | symbol denotes an “or” relationship between two features. When this
symbol appears between two features on the same line, you can use either
feature (but not both). When this symbol appears at the end of a line, you can
use the feature on that line, or the one below it.

Many CLI commands have nested dependencies, which make features optional in some
contexts, and mandatory in others. The three hypothetical features shown below
demonstrate this principle.
[ feature_1 { feature_2 | feature_3 } ]
In this example, the delimiters [ and ] surround the entire clause. Consequently, you can
omit feature_1, feature_2, and feature_3, and still execute the command successfully.
However, because the { and } delimiters surround feature_2 and feature_3, you must
include either feature_2 or feature_3 if you include feature_1. Otherwise, you cannot
successfully execute the command.
The following example shows some of the set interface command’s feature dependencies.
set interface vlan1 broadcast { flood | arp [ trace-route ] }
The { and } brackets indicate that specifyng either flood or arp is mandatory. By contrast,
the [ and ] brackets indicate that the arp option’s trace-route switch is not mandatory.
Thus, the command might take any of the following forms:
ns-> set interface vlan1 broadcast flood
ns-> set interface vlan1 broadcast arp
ns-> set interface vlan1 broadcast arp trace-route

As you execute CLI commands using the syntax descriptions in this manual, you may find
that certain commands and command features are unavailable for your NetScreen device
model.
Because NetScreen devices treat unavailable command features as improper syntax,
attempting to use such a feature usually generates the unknown keyword error
message. When this message appears, confirm the feature’s availability using the ?
switch. For example, the following commands list available options for the set vpn
command:
ns-> set vpn ?
ns-> set vpn vpn_name ?
ns-> set vpn gateway gate_name ?
