Thank you all for the wonderful help and suggestions, Really appreciated.
so SPC 2 card throuput is limitation 3G? if not what is the limitation value for spc2?
This SRX 5400 only for ipsec, not for non ipsec testing so I can't see any non ipsec traffic.
I will ask user setup again and will monitor spc performance and cos values.

Hi Bala,
First of all i think u need to upgrade your firmware first. If after u upgrade the result is same then possiblity due to maximum limitation SPC2 card. Please take note on SRX5k series all the security feature throughput depend on SPC2 card.
Thanks

Thank you, it means SPC2 not supported for SRX 5400, needs to get a New SPC3 card in order to work? so what is the limitation for SPC2, no throuput at all? Can I run 1G date on SPC2? just want to understand.
Thanks alot.

Hi,
One SPC2 model just can cater 5g IPSec throughput only. So u need to change ypur SPC2 to SPC3 since SRX5400 just have limited slot.
Thanks

Thank you Steve again, we are not running any vpn monitoring, The Main issue on SRX 5400 it's tunnel is not stable when traffic started, the problem is peer dead detection happening due the peer ike unreachable message from remotes site. Why this happening because of srx 5400 kind of congestion, around ~7G data going through that interface link, but as I told you already it's 20G link, I am quite not sure why srx 5400 making congestion and packet loss coming and then peer ip not reachable once in a while and tunnel going up/down, because BW is 20G.
is there any way I can check on hardware level All the cards working as expected? Also this release JUNOS 12.3X48-D105.4 will support 7G throuput?
Please advice.

For the vpn troubleshooting the logging level would need to be increased to information level to get detailed messages as noted in the kb.
Also verify that vpn monitoring is either not in use or adjusted as needed per the later steps.
On the upgrade path, there are maximum jump levels that would need to be observed. And those files are not publicly available as you note. This requires opening a service ticket with JTAC support. The particular versions vary by platform which is why they were running the open sessions a few months back. But a JTAC ticket can also help parse this as well.
The alternative is to do a clean boot format install on the SRX. Naturally, this deletes the current configuration so a backup would need to be pulled. And this would take the device to factory default so local physical access also needed. But you can format to any version with the upgrade jump maximums in play.

Thank you Steve for the prompt reply and really appreciated.
First issue, for the tunnel up/down, this is only happening when traffic started otherwise tunnel always are up and not fluctuating, I tested SRX 5800 with same config and it's working fine, so something SRX 5400 it's causing issue but I can't find any alarm on srx 5400 in order to debug, Maybe any card issue or software? This is first time I am testing ipsec on SRX 5400.
This is the reason I am thinking maybe update the software
I can't see much info on FAQ about the upgrade, SRX 5400 with Routing engine SRX5k RE-1800X4 recommended load is
Also I checked on juniper website under download for SRX 5400, only showing load is 12.3 X48 and then showing 19.3 there is no middle releases there, not sure what is the full path in order to reach 21.4.
Curently SRX 5400 running this firmware, JUNOS 12.3X48-D105.4 .
Please suggest how move forward.

For a vpn that is going up/down follow the outline in this kb article to identify the cause.
https://supportportal.juniper.net/s/article/SRX-How-to-troubleshoot-a-VPN-tunnel-that-is-going-up-and-down?language=en_US
Upgrades from the EOL version 12 generally require multiple steps up to a current version. Check the FAQ and other notes on these old version upgrades from this previous announcement.

Hi,
I have srx 5400 just recently installed and setup done for ipsec, tunnel is stable if no traffic, but tunnel is going up/down when traffic started. Traffic is less than 7 GB, but link BW is 20G, so I don't think this causing issue.
There is no alarm on SRX,
Could you please someone suggest, maybe load issue or SCB/SPC issue?
SRX 5400 running on JUNOS 12.3X48-D105.4, if you think load issue can I upgrade to 19.3R1.8..
Please kindly advice.
Thanks,
Nesan
