Hierarchy Level

Description

Assign a name to a line-card upgrade group being created for nonstop software upgrade (NSSU).

To reduce the time an NSSU takes, you can configure line-card upgrade groups on an EX6200 or EX8200 switch with redundant Routing Engines; EX8200 Virtual Chassis; EX4650 Virtual Chassis; QFX3500, QFX3600, and QFX5100 Virtual Chassis; and QFX5100 Virtual Chassis Fabric (VCF).

NSSU upgrades the groups in the order that they appear in the configuration (in other words, in the order you configure them). If you do not define any line-card upgrade groups, NSSU upgrades line cards or members of a Virtual Chassis or VCF one at a time in ascending order by slot or member number.
