[j-nsp] Automation of EX code upgrade

[Georgios Vlachos]

Junos Space (VM version) is pretty inexpensive as well for required
functionality using the built in application "Network Management Platform". 

Thanks,
George

If you're talking green fields (out-of-the-box) then there are a couple of
ways depending on the current Junos release the switch is running:

<12.2 - Automatic Software Download

ies-software-automatic-download-upgrading.html

>=12.2 - Zero Touch Provisioning

http://www.juniper.net/techpubs/en_US/junos12.2/topics/concept/software-imag
e-and-configuration-automatic-provisioning-understanding.html

Try to stagger upgrades if you can, or learn the effects of having a hundred
switches hitting a TFTP server for a ~110MB image file.  Neither of these
methods will display the success of the upgrades though.

If your switches are already deployed, then a better way to do it is with
Junos Space.  

The nice thing about the Space method is that you can upgrade smaller groups
of switches at a time, pre-stage the images up to each switch and schedule
the entire process.  Each upgrade is given a Job ID and that Job ID will
return success or failure depending on the outcome, even in the pre-staging
if you don't have room on your flash for the image..

This functionality is built into the base Space platform too, which you can
download and install with a 60(?)-day trial license.

Cheers,

Ben
