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.
request system reboot
request vmhost reboot
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 Example showing the command is no longer valid: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
