Command introduced in Junos OS Release 10.4 for EX Series switches.
(EX8200 switches only) Perform a nonstop software upgrade (NSSU) of an EX8200
switch with redundant Routing Engines. When you execute this command, both the
backup and master Routing Engines are upgraded with minimal traffic disruption. At the
end of the upgrade, the previous backup Routing Engine is the new master Routing Engine.
This command has the following requirements:
The Routing Engines must be running the same Junos OS release.
Graceful Routing Engine switchover (GRES) must be enabled.
Nonstop active routing (NSR) must be enabled.
The command must be executed from the master Routing Engine.
For minimal traffic disruption, you must define link aggregation groups (LAGs) such
that the member links reside on different line cards.
