vPC Auto-recovery Feature

[SATORU SAEGUSA]

Hi, all

I understood vPC auto-recovery feature as the following but are they correct?

• vPC auto-recovery becomes effective command only when vPC role is secondary.
• In order to change to secondary state, a pair of vPC devices need synchronize.
• Even if one of a pair vPC devices fails boot after a power cut, vPC auto-recovery does not work.  The vPC role is "none established" because the vPC device does not synchronize with peer vPC device.

Thank you for your cooperation in advance.

Hi Satoru,

This document explains pretty well how auto-recovery works.

Hi richbarb,

Thank you for introducing me to the document.
The document is easy to understand, and I correctly understood vPC auto-recovery reload-delay.
