The show configuration mode command displays the current configuration for a device running Junos OS.

Display the Current Configuration

To display the current configuration for a Juniper Networks device, use the show command in configuration mode. This command displays the configuration at the current hierarchy level or at the specified level.

content_copy zoom_out_map
user@host# show <statement-path> 

The configuration statements appear in a fixed order, interfaces appear alphabetically by type, and then in numerical order by slot number, PIC number, and port number. Note that when you configure the device, you can enter statements in any order.

You also can use the CLI operational mode show configuration command to display the last committed configuration, which is the configuration currently running on the router:

content_copy zoom_out_map
user@host> show configuration 

When you show a configuration, a timestamp at the top of the configuration indicates when the configuration was last changed:

content_copy zoom_out_map
## Last commit: 2018-07-18 11:21:58 PDT by echen
version 8.3

If you have omitted a required statement at a specific hierarchy level, when you issue the show command in configuration mode, a message indicates which statement is missing. If a mandatory statement is missing, the CLI continues to display this message each time you issue a show command.

For example:

content_copy zoom_out_map
[edit]
user@host# show
protocols {
    pim {
        interface so-0/0/0 {
            priority 4;
            version 2;
            # Warning: missing mandatory statement(s): 'mode'
        }
    }
}

Unsupported statements included in the CLI configuration are displayed with the “unsupported” text in the configuration. For example, if a statement is configured on an unsupported platform, the CLI displays a message that the statement is ignored in the configuration because it is configured on an unsupported platform. When you issue the show command with the | display xml option, you can see the unsupported="unsupported” attribute for configuration that is unsupported.

The “unsupported” attribute included in text configuration or XML configuration is provided to scripts when the unsupported="unsupported" attribute is included in the <get-configuration> RPC call.

Example: Display the Current Configuration

The following example shows how you can display the current device configuration.

Set and commit a configuration:

content_copy zoom_out_map
[edit]
user@host# set protocols ospf area 0.0.0.0 interface xe-0/0/0 hello-interval 5 
[edit]
user@host# commit 
commit complete
[edit]
user@host# quit
exiting configuration mode

Display the current configuration:

content_copy zoom_out_map
[edit]
user@host# show 
protocols {
    ospf {
        area 0.0.0.0 {
            interface xe-0/0/0 {
                hello-interval 5;
            }
        }
    }
}

Display the configuration at a particular hierarchy:

content_copy zoom_out_map
[edit]
user@host# show protocols ospf area 0.0.0.0
interface xe-0/0/0 {
    hello-interval 5;
}

Move down a level and display the configuration at that level:

content_copy zoom_out_map
[edit]
user@host# edit protocols ospf area 0.0.0.0
[edit protocols ospf area 0.0.0.0]
user@host# show 
interface xe-0/0/0 {
    hello-interval 5;
}

Display the last committed configuration:

content_copy zoom_out_map
user@host> show configuration
## Last commit: 2018-08-10 11:21:58 PDT by user
version 8.3
protocols {
ospf {
    area 0.0.0.0 {
        interface xe-0/0/0 {
            hello-interval 5;
        }
    }
}
}

Display Additional Information About the Configuration

In configuration mode only, to display additional information about the device configuration, use the display detail command after the pipe ( | ) in conjunction with a show command. The additional information includes the help string that explains each configuration statement and the permission bits required to add and modify the configuration statement.

content_copy zoom_out_map
user@host# show <hierarchy-level> | display detail 

For example:

content_copy zoom_out_map
[edit]
user@host# show | display detail

Display set Commands from the Configuration

In configuration mode, you can display the configuration as a series of configuration mode commands required to re-create the configuration. This is useful if you are not familiar with how to use configuration mode commands or if you want to cut, paste, and edit the displayed configuration.

To display the configuration as a series of configuration mode commands, which are required to re-create the configuration from the top level of the hierarchy as set commands, issue the show configuration mode command with the display set option:

content_copy zoom_out_map
user@host# show | display set <explicit>

When you issue the show configuration command with the | display set pipe option to view the configuration as set commands, those portions of the configuration that you do not have permissions to view are substituted with the text ACCESS-DENIED.

You can use the <explicit> option with the | display set command, to explicitly display all the configuration statements that the system internally creates, as a series of set commands, when you configure certain statements from the top level of the hierarchy.

For example, assume you issue the set interfaces ge-0/0/0.0 family inet configuration mode command. You then show the resulting configuration with the show interfaces ge-0/0/0 | display set command. The output displays the same set command you entered. If you include the explicit argument, the output also shows the configuration statements needed to create the hierarchy where the family inet statement is specified. Specifically for this example, the output therefore includes the set interfaces ge-0/0/0 unit 0 statement in addition to the set interfaces ge-0/0/0.0 family inet statement.

Example: Display set Commands with the match Option

Example: Display set Commands from the Configuration

Display the set commands from the configuration at the [edit interfaces] hierarchy level:

content_copy zoom_out_map
[edit interfaces xe-0/0/0]
user@host# show 
unit 0 {
    family inet {
        address 192.107.1.230/24;
    }
    family iso;
    family mpls;
}
inactive: unit 1 {
    family inet {
        address 10.0.0.1/8;
    }
}

[edit interfaces ge-0/0/0]
user@host# show | display set 
set interfaces ge-0/0/0 unit 0 family inet address 192.107.1.230/24
set interfaces xe-0/0/0 unit 1 family inet address 10.0.0.1/8
deactivate interfaces xe-0/0/0 unit 1 

[edit interfaces ge-0/0/0]
user@host# show | display set | explicit
set interfaces ge-0/0/0 unit 0 family inet address 192.107.1.230/24
set interfaces xe-0/0/0 unit 0 family iso
set interfaces xe-0/0/0 unit 0 family mpls
set interfaces ge-0/0/0 unit 0 family inet
set interfaces ge-0/0/0 unit 0
set interfaces xe-0/0/0 unit 1 family inet address 10.0.0.1/8
deactivate interfaces xe-0/0/0 unit 1 

To display the configuration as a series of configuration mode commands required to re-create the configuration from the current hierarchy level, issue the show configuration mode command with the show | display set relative option. You can use the <explicit> option to explicitly display, as a series of commands, all the configurations that the system internally creates when you configure certain statements from the current hierarchy level.

content_copy zoom_out_map
[edit interfaces fe-0/0/0]
user@host# show
unit 0 {
family inet {
address 192.107.1.230/24;
}
family iso;
family mpls;
}
inactive: unit 1 {
family inet {
address 10.0.0.1/8;
}
}

[edit interfaces xe-0/0/0] 
user@host# show | display set relative 
set unit 0 family inet address 192.107.1.230/24 
set unit 0 family iso 
set unit 0 family mpls 
set unit 1 family inet address 10.0.0.1/8 
deactivate unit 1

user@host# show | display set relative | explicit
set unit 0 family inet address 192.168.1.230/24
set unit 0 family inet
set unit 0 family iso
set unit 0 family mpls
set unit 0
set unit 1 family inet address 10.0.0.1/8
set unit 1 family inet
deactivate unit 1

Example: Display set Commands with the match Option

To display the configuration as set commands and search for text matching a regular expression by filtering output, specify the match option after the pipe ( | ):

content_copy zoom_out_map
user@host# show | display set | match regular-expression

Display IP addresses associated with an interface:

content_copy zoom_out_map
xe-2/3/0 {
        unit 0 {
                family inet {
                        address 192.107.9.106/30;
        }
    }
}
so-5/1/0 {
        unit 0 {
                family inet {
                        address 192.107.9.15/32 {
                                destination 192.107.9.192;
            }
        }
    }
}
lo0 {
        unit 0 {
                family inet {
                        address 127.0.0.1/32;
        }
    }
}
user@host# show interfaces | display set | match address
set interfaces xe-2/3/0 unit 0 family inet address 192.168.9.106/30
set interfaces so-5/1/0 unit 0 family inet address 192.168.9.15/32 destination 192.168.9.192
set interfaces lo0 unit 0 family inet address 127.0.0.1/32
