Markus, I have jbundle packages present in /var/sw/pkg/ directory:

Oliver, if I check the release notes for versions 12.3, 13.2, 13.3 or 14.1 then they all say that one can not issue the "request system software rollback" command to return to previously installed software. According to Junos command reference, the behavior of "request system software rollback" command changed in version 12.1. Since Junos 12.1 the "request system software rollback" restores the system to known good state. What does this known good state mean? In addition, I have one older router which had Junos 7.4R1.7 installed. I executed "request system snapshot" and then upgraded to Junos 8.5R4.3 using a jinstall package. Once the router booted up with the Junos 8.5R4.3 I executed "request system software rollback" command, but this still does not seem to do anything: root> show version brief Model: m20 JUNOS Base OS boot [8.5R4.3] JUNOS Base OS Software Suite [8.5R4.3] JUNOS Kernel Software Suite [8.5R4.3] JUNOS Crypto Software Suite [8.5R4.3] JUNOS Packet Forwarding Engine Support (M/T Common) [8.5R4.3] JUNOS Packet Forwarding Engine Support (M20/M40) [8.5R4.3] JUNOS Online Documentation [8.5R4.3] JUNOS Routing Software Suite [8.5R4.3] root> file list detail /var/sw/pkg/ /var/sw/pkg/: total 750828 -r-xr-xr-x 1 root wheel 68303371 Oct 16 14:11 jbundle-7.4R1.7.tgz* -rw-r--r-- 1 root wheel 155872954 Oct 16 14:38 jbundle-8.5R4.3.tgz -rwxr-xr-x 1 root wheel 160039672 Oct 16 14:28 jinstall-8.5R4.3-domestic-signed.tgz* -rw-r--r-- 1 root wheel 122 Oct 16 14:38 rollback root> request system software rollback root> Any comments? thanks, Martin On 10/2/15, Olivier Benghozi <olivier.bengh...@wifirst.fr> wrote: > http://www.juniper.net/techpubs/en_US/junos13.3/information-products/topic-collections/release-notes/13.3/topic-83364.html#rn-downgrade > <http://www.juniper.net/techpubs/en_US/junos13.3/information-products/topic-collections/release-notes/13.3/topic-83364.html#rn-downgrade> > > "To downgrade from Release 13.3 to another supported release, follow the > procedure for upgrading, but replace the 13.3 jinstall package with one that > corresponds to the appropriate release." > > and > > "Note: After you install a Junos OS Release 13.3 jinstall package, you > cannot issue the request system software rollback command to return to the > previously installed software.
