CLI Configuration Mode ! 645
Appendix A: Command-Line Interface Overview
The CLI represents the statement path shown in Figure 235 as [protocols ospf area
area-number interface interface-name ], and displays the configuration as follows:
protocols {
ospf {
area 0.0.0.0 {
interface so-0/0/0 {
hello-interval 5;
}
interface so-0/0/1 {
hello-interval 5;
}
}
}
}
The CLI indents each level in the hierarchy to indicate each statement’s relative
position in the hierarchy and generally sets off each level with braces, using an
open brace at the beginning of each hierarchy level and a closing brace at the end.
If the statement at a hierarchy level is empty, the braces are not printed. Each leaf
statement ends with a semicolon. If the hierarchy does not extend as far as a leaf
statement, the last statement in the hierarchy ends with a semicolon.
The CLI uses this indented representation when it displays the current system
configuration, and you use this format when creating ASCII files that contain the
software configuration. However, the format of ASCII configuration files is not as
strict as the CLI output of the configuration. Although the braces and semicolons are
required, the indentation and use of new lines, as shown above, are not required in
ASCII configuration files.
