Aaron, 1. yes, I've seen this kb, but when I had someone I trust look at the diff, + the nature of the changes they were suggesting, I just wasn't comfortable making those changes. I personally avoided this at all cost. In my case, installs took about ~7 minutes per acx in a maintenance window and a majority of the routers are local, so it wasn't a big deal.
2. Not that I'm aware. I was including the caveat because for some reason during initial config we used vme.0 interfaces instead of em0.0 and I ran into issues with it not working properly in a lab setting and vme.0 was the gotcha for me. By the way, I was seeing the same PR1419761 issues you are seeing, those have been resolved since upgrading. -kv -----Original Message----- From: aar...@gvtc.com <aar...@gvtc.com> Sent: Wednesday, September 2, 2020 1:22 AM To: Kody Vicknair <kvickn...@reservetele.com>; 'Roger Wiklund' <roger.wikl...@gmail.com>; 'Colton Conor' <colton.co...@gmail.com> Cc: 'Juniper List' <juniper-nsp@puck.nether.net> Subject: RE: [j-nsp] How to pick JUNOS Version *External Email: Use Caution* 1 - https://link.edgepilot.com/s/6890e15f/hA34W4NyWUumQulQkNIdtw?u=https://kb.juniper.net/InfoCenter/index?page=content%26id=KB33988 (pretty sure that avoids the usb craziness, if memory serves me right, I think Juniper created that KB from my lab 5048 test back in March 2019. Now I'm wondering if I tried to go to like 15.x.D61 or something prior to trying to go to 17.3 if that would've helped) 2 - Virtual Chassis on an ACX5048? Can you do that? -Aaron -----Original Message----- From: Kody Vicknair <kvickn...@reservetele.com> Sent: Tuesday, September 1, 2020 7:52 PM To: aar...@gvtc.com; 'Roger Wiklund' <roger.wikl...@gmail.com>; 'Colton Conor' <colton.co...@gmail.com> Cc: 'Juniper List' <juniper-nsp@puck.nether.net> Subject: RE: [j-nsp] How to pick JUNOS Version 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: aar...@gvtc.com <aar...@gvtc.com> Sent: Tuesday, September 1, 2020 5:34 PM To: Kody Vicknair <kvickn...@reservetele.com>; 'Roger Wiklund' <roger.wikl...@gmail.com>; 'Colton Conor' <colton.co...@gmail.com> Cc: 'Juniper List' <juniper-nsp@puck.nether.net> 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 Links contained in this email have been replaced.
