Configuration Output Format Overview
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 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.
Table 31: Output Locations for Layer 2 and Layer 3 Interface Configurations
Format | Layer 2 Only Interfaces | Layer 3 Only Interfaces | Layer 2 and Layer 3 Combination Interfaces |
|---|---|---|---|
Format 1 | Entire configuration appears in the default router output | Entire configuration appears in the layer 3 virtual router output | Layer 2 configuration appears in the default router the layer 3 virtual router output |
Format 2 | Entire configuration appears in the default router output | Entire configuration appears in the layer 3 virtual router output | Layer 2 configuration appears in the default router output; layer 3 configuration appears in the layer 3 virtual router output |
