To upgrade an individual JUNOS Software package, follow these steps:
1.
Download the software packages you need from the Juniper Networks Support
Web site at
http://www.juniper.net/support/ . Choose either the Canada and U.S.
Version or the Worldwide Version.
To download the software packages, you must have a service contract and an
access account. If you need help obtaining an account, complete the registration
form at the Juniper Networks Web site:
https://www.juniper.net/registration/Register.jsp .
NOTE: We recommend that you upgrade all individual software packages using an
out-of-band connection from the console or
fxp0
interface, because in-band
connections can be lost during the upgrade process. On a TX Matrix Plus router and
the T1600 routers in a routing matrix, the management Ethernet interface is
em0
.
2.
Back up the currently running and active file system so that you can recover to
a known, stable environment in case something goes wrong with the upgrade:
user@host> request system snapshot
The root file system is backed up to /altroot , and /config is backed up to /altconfig .
The root and /config file systems are on the router’s CompactFlash card, and the
/altroot
and
/altconfig
file systems are on the router’s hard disk.
NOTE: After you issue the request system snapshot command, you cannot return to
the previous version of the software, because the running copy and the backup copy
of the software are identical.
3.
If you are copying multiple software packages to the router, copy them to the
/var/tmp
directory on the hard disk:
user@host> file copy ftp :// username : prompt@ftp . hostname
. net / filename /var/tmp/ filename
4.
Add the new software package:
user@host> request system software add/var/tmp/ installation package validate
installation-package
is the full URL to the file.
The system might display the following message:
pkg_delete: couldn’t entirely delete package
This message indicates that someone manually deleted or changed an item that
was in a package. You do not need to take any action; the package is still properly
deleted.
If you are upgrading more than one package at the same time, add jbase first.
If you are using this procedure to upgrade all packages at once, add them in the
following order:
