QFX10002-60C and PTX-10002-60C do not support ‘request system reboot’



Article ID: KB36367 KB Last Updated: 26 Apr 2021Version: 1.0
The command 'request system reboot' is not supported on the QFX10002-60C and PTX-10002-60C for any Junos version.  If ‘request system reboot’ is issued by mistake, then it will trigger a hypervisor reboot instead; which may lead to unexpected behavior.  As a replacement, ‘request vmhost reboot’ is the recommended command for these platforms.
Using 'request system reboot’ can cause a hypervisor reboot as well as unexpected behavior; such as kernel panic and FPC host loopback wedge (where interfaces are stuck in a down state).
QFX10002-60C and PTX-10002-60C do not support ‘request system reboot’ on any Junos version.  Because of this, the command ‘request system reboot’ is deprecated for vmhost platforms from Junos OS release 19.1 onwards through PRs 1386279 and 1411167.

Example showing the command is no longer valid:
root@qfx10002-60c> show version
Model: qfx10002-60c
Junos: 19.3R2-S3.4

root@qfx10002-60c> request system reboot
error: command is not valid on the qfx10002-60c

Hence ‘request vmhost reboot’ is recommended for these platforms.
The recommendation is to use ‘request vmhost reboot’ for  the QFX10002-60C and PTX-10002-60C platforms.
