request node halt (Junos OS Evolved)



Use this command to halt a Routing Engine. Halt instructs the hardware to stop all CPU functions but leave the node in a powered-on, standby state. To un-halt the node, do one of the following:

  • Issue the request chassis cb slot slot-number online operational mode command from the primary Routing Engine.

  • Log in to the console port for that node and press any key to reboot the node.


We do not recommend leaving a node halted for a long period of time, because the node is not available as a backup in case something happens to the primary Routing Engine.



Specify the Routing Engine node (re0 | re1) to halt. You can halt the primary Routing Engine.

(at time | in minutes)

(Optional) Specify when the action should occur, either in time, in hh:mm format, or in number of minutes.
