Copy a File on a Routing Engine

Purpose

When you configure one Routing Engine and another Routing Engine needs to have a similar configuration, or when you upgrade the JUNOS software version on one Routing Engine, you can simplify the process by copying files from one Routing Engine to another.

To copy a file, follow these steps:

1. Copy a File from One Routing Engine to Another
2. Copy Files between the Local Router and a Remote System

Copy a File from One Routing Engine to Another

Purpose

When you have a dual Routing Engine configuration, you can copy a configuration file from Routing Engine 0 to Routing Engine 1 or vice versa.

Action

To copy a configuration file from Routing Engine 0 to Routing Engine 1, use the following JUNOS command-line interface (CLI) operational mode command:

Sample Output

Meaning

In this case, source is the name of the configuration file on Routing Engine 0. Configuration files are stored in the directory /config. The active configuration is /config/juniper.conf, and older configurations are in /config/juniper.conf {1...9 }. destination is a file on Routing Engine 1.

Note: Refer to Maintain a Single Configuration File for Both Routing Engines for details about naming the Routing Engines correctly.

Copy Files between the Local Router and a Remote System

Action

You can copy a configuration file from a Routing Engine to a remote system in the network using the File Transfer Protocol (FTP) or secure copy protocol (scp) in any one of the following ways:

• To use anonymous FTP to copy a local file to a remote system, enter the following command:

  root@host> file copy filename ftp://hostname/filename

  In the following example, /config/juniper.conf is the local file and hostname is the FTP server:

  root@host> file copy /config/juniper.confftp://hostname/juniper.confReceiving ftp: //hostname/juniper.conf (2198 bytes): 100% 
  2198 bytes transferred in 0.0 seconds (2.69 MBps)

• To use FTP where a valid username and password are required, enter the following command:

  root@host> file copy filename ftp://user:password@hostname/filename

  In the following example, /config/juniper.conf is the local file, user is the username, testing123 is the password, and hostname is the FTP server:

  root@host> file copy /config/juniper.conf ftp://user:testing123@hostname/juniper.conf
  Receiving ftp: //user:testing123@hostname/juniper.conf (2198 bytes): 100%
  2198 bytes transferred in 0.0 seconds (2.69 MBps)

• To use FTP where you require more privacy and are prompted for a password, enter the following command:

  root@host> file copy filename ftp://user@hostname/filename

  In the following example, /config/juniper.conf is the local file, user is the username, and hostname is the FTP server:

  root@host> file copy /config/juniper.conf ftp://user@hostname/juniper.conf
  Password for user@hostname: ******
  Receiving ftp: //user@hostname/juniper.conf (2198 bytes): 100%
  2198 bytes transferred in 0.0 seconds (2.69 MBps)

• To use scp to copy a local file to a remote system, enter the following command:

  root@host> file copy filename scp://user@hostname/path/filename

  In the following example, /config/juniper.conf is the local file, user is the username, and ssh-host is the scp server:

  root@host> file copy /config/juniper.conf scp://user@ssh-host/tmp/juniper.conf
  user@ssh-host's password: ******
  juniper.conf         100% |*********************************************************************************|  2198       00:00

Note: You cannot use scp or ssh to copy a file in the worldwide version of the JUNOS software.
