Overview
Learn how to upgrade a switch in vPC topology that holds either the Secondary or Operational Secondary vPC roles.
Summary
This procedure describes the upgrade process initiated by the install all command on the vPC secondary switch, including compatibility checks, image installation, stateful restart, and configuration unlock on both primary and secondary switches to complete the upgrade.
Step 1 and Step 8 differ from a switch upgrade in a non-vPC topology.
Workflow
- The install all command issued on the vPC secondary switch triggers the installation upgrade.
- The compatibility checks display the impact of the upgrade.
- The installation proceeds or not based on the upgrade impact.
- The current state is saved.
- The system unloads and runs the new image.
- The stateful restart of the system software and application occurs.
- The installer resumes with the new image.
- The configuration is unlocked on the primary and secondary switches.
- The installation is complete.
