Release Information
Statement introduced in Junos OS Release 10.4 for EX Series switches.
Description
(EX6200 switches, EX8200 switches, and EX8200 Virtual Chassis only) Define a line-card upgrade group for nonstop software upgrade (NSSU). All line cards in an upgrade group are upgraded to the new software version at the same time when an NSSU is initiated and an at least one upgrade group is configured.
You use this statement to configure line-card upgrade groups only. Line card upgrade groups are not required to initiate an NSSU, and are not supported on some EX Series switches that support NSSU. The request system software nonstop-upgrade command is used to initiate an NSSU.
The remaining statements are explained separately.
Default
If no line-card upgrade groups are defined, NSSU upgrades line cards one at a time in ascending order by slot number.
