[j-nsp] Junos upgrade how to

[Prabhu Gurumurthy]

No, not needed, if you do not have the stanza mentioned, it would upgrade all the fpc's at the same time

The order of operation is the following
Secondary RE upgrade
Failover to secondary RE
Upgrade now secondary, previous primary
Then upgrade the fpc, if stanza given then upgrade them in the order mentioned or all of them at the same time

Am I making sense?

Hi Prabhu
Thanks for your help.

Regarding 8200 is this part mandatory (taken from the link you gave):

root# show chassis 
nssu {
     upgrade-group Bala {
         fpcs [ 0 2 4 ];
     }
     upgrade-group Mridhu {
         fpcs [ 1 3 ];
     }

Best regards

Hello James,

Yes, EX 8200 running 11.4 supports NSSU, It has supported NSSU since 10.4

Juniper KB: http://kb.juniper.net/InfoCenter/index?page=content&id=KB19987

The KB method(s) worked without any issues for us when we did twin EX 8200 upgrades with dual RE.

WRT to EX 4200, also supports NSSU, but you gotta be on 12.1 or over (http://www.juniper.net/documentation/en_US/junos13.3/topics/concept/nssu-ex-series.html)We have used NSSU on our production EX series equipment and have not seen anything that was really concerning or confusing for that matter.


WRT to SRX, sorry I cannot help with ISSU/NSSU on that one.

Hope this helps,

Prabhu
