warning: Traffic will be interrupted while the PFE is re-initialized
Toggle mastership between Routing Engines ? [yes,no] (no) yes
Resolving mastership...
Complete. The other Routing Engine becomes the master.
If the Routing Engines are running the same Junos OS Release and are configured for
graceful switchover, the standby Routing Engine immediately assumes Routing Engine
functions and there is no interruption to packet forwarding. Otherwise, packet
forwarding halts while the standby Routing Engine becomes the master and the Packet
Forwarding Engine components reset and connect to the new master Routing Engine.
For information about configuring graceful switchover, see the Junos OS High Availability
Configuration Guide.
NOTE: Packet transport switch performance might change if the standby
Routing Engine's configuration differs from the former master's
configuration. For the most predictable performance, configure the two
Routing Engines identically, except for parameters unique to a Routing
Engine, such as the hostname defined at the [edit system] hierarchy level
and the management interface (em0 or equivalent) defined at the [edit
interfaces] hierarchy level.
To configure Routing Engine-specific parameters and still use the same
configuration on both Routing Engines, include the appropriate
configuration statements under the re0 and re1 statements at the [edit
groups] hierarchy level and use the apply-groups statement. For
instructions, see the Junos OS System Basics Configuration Guide.
3. To halt the packet transport switch:
user@host> request system halt
Halt the system ? [yes,no] (no) yes
*** FINAL System shutdown message from user@host ***
System going down IMMEDIATELY
Terminated
...
syncing disks... 11 8 done
The operating system has halted.
Please press any key to reboot.
NOTE: The request system halt command halts all Routing Engines on
the control plane from which it was issued. To reboot a Routing Engine
that has been halted, you must connect through the console. For more
information about system commands, see the Junos OS System Basics and
Services Command Reference.
