Defining the Configuration Output Format

The JUNOSe show configuration command displays the entire system configuration.
For very large configurations, the show configuration report can take a long time to
generate and display.
The service show-config format command enables you to run the show
configuration command using one of two formats original format (format 1; the
default) and a format that provides a much faster output (format 2). Using format 2
can significantly reduce the amount of time it takes to generate and display
configurations that contain three or more virtual routers and a large number of
interfaces.
The primary difference between format 1 and format 2 output is the way in which
each displays layer 2 and layer 3 interface configurations. Table 31 on page 262
indicates where layer 2 and layer 3 interface configurations appear within the show
configuration command output when the system is using format 1 or format 2.
