1. I did a direct USB recovery format boot from 17.4r2-S11, and afterwards recovered configs from FTP. The reason for this was because 15.1x54D51 screws up your /tmp directory and you wont have enough free space no matter what you try. - at least, this was the case for my installs
2. One caveat of mgmt_junos routing-instance is you wont be able to utilize vme interfaces (so if you have a virtual chassis, it still won't work), to get around this I did the following: set system management-instance rename interfaces vme.0 to em0.0 set routing-instances mgmt_junos description "OOB Mgmt Instance" set routing-instances mgmt_junos routing-options static route 0.0.0.0/0 next-hop x.x.x.x set snmp interface em0.0 set snmp routing-instance-access set system ntp server x.x.x.x routing-instance mgmt_junos set system ntp server x.x.x.x routing-instance mgmt_junos and deleted the static route for management out of the default inet.0 table Goodluck! -KV -----Original Message----- From: [email protected] <[email protected]> Sent: Tuesday, September 1, 2020 5:34 PM To: Kody Vicknair <[email protected]>; 'Roger Wiklund' <[email protected]>; 'Colton Conor' <[email protected]> Cc: 'Juniper List' <[email protected]> Subject: RE: [j-nsp] How to pick JUNOS Version *External Email: Use Caution* Thanks Kody, 2 questions sir... I recently began moving towards that same version (17.4R2-S11) as I was hitting PR1419761 high cpu. 1 - did you upgrade straight from 15.1x54D51 to 17.4R2-S11 , or did you take an intermediate step? Asking since JTAC recently told me that this was too far of a jump and I should go through 17.1 on my way to 17.4 15.1X54--------17.1----------17.4 2 - do you use that mgmt_junos route instance? I would've expected to see em0 or fxp0 in there or something like that, but I don't. name@acx5048> show system information | grep Junos Family: junos Junos: 17.4R2-S11 name@acx5048> show route instance mgmt_junos detail mgmt_junos: Router ID: 0.0.0.0 Type: forwarding State: Active -Aaron _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
