member (NSSU Upgrade Groups)


Hierarchy Level


Specify the Virtual Chassis member whose line-card slot numbers you are assigning to an NSSU upgrade group.


This statement is not applicable to Virtual Chassis or VCF member switches that do not support separate line cards. To configure Virtual Chassis or VCF member switches that do not have separate line cards into an NSSU upgrade group, use the fpcs statement alone, and specify the Virtual Chassis or VCF member IDs to include in the upgrade group in place of line card slot numbers.

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

To configure an upgrade group that includes line cards on different switches that support multiple line cards and comprise a Virtual Chassis, use this statement hierarchy with the fpcs option to first specify the Virtual Chassis member ID and then 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.



The ID of the Virtual Chassis or VCF member switch containing one or more line cards to include in an NSSU upgrade group.

The remaining statement is explained separately. See CLI Explorer.
