Description

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.

Symptoms

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).

Solution

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Example showing the command is no longer valid: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.
