fpcs (NSSU Upgrade Groups)

Syntax

Hierarchy Level

Description

Configure switch line cards, Virtual Chassis member switches, or Virtual Chassis Fabric (VCF) member switches as part of an NSSU upgrade group.

To reduce the time an NSSU takes, you can configure line-card upgrade groups for an EX6200 or EX8200 switch with redundant Routing Engines; an EX8200 Virtual Chassis; an EX4650 Virtual Chassis with more than three member switches; QFX3500, QFX3600, and QFX5100 Virtual Chassis; or a QFX5100 Virtual Chassis Fabric (VCF). NSSU upgrades the devices in the order in which you configure the upgrade groups, so you can also use upgrade groups to control the upgrade sequence.

For switches that have separate line cards, use this statement to assign one or more line cards to an NSSU upgrade group based on their line-card slot numbers.

For Virtual Chassis or VCF member switches that do not have separate line cards, use this statement to assign one or more Virtual Chassis or VCF members to an NSSU upgrade group by specifying their member IDs.

Note:

For a Virtual Chassis or VCF, you do not use this statement with the member option. When to use the member statement hierarchy is explained next.

To configure an upgrade group that includes line cards on switches that support multiple line cards and comprise a Virtual Chassis, use this statement with the member option to specify the Virtual Chassis member ID and the desired line card slot number or numbers on that member switch to include in the upgrade group. Use multiple statements to add line cards from different Virtual Chassis members to the upgrade group.

Options
