Installing Licenses After Standalone Switches Are Added to a Stack System

What Can I Do If No License Is Installed on Standalone Switches Before They Are Added to a Stack

    After standalone switches are added to a stack system, apply for a license file that contains the ESNs of all member switches, and install the license file in the stack system.

What Can I Do If Licenses Have Been Installed on Standalone Switches Before They Are Added to a Stack

    To ensure that the stack license can be used normally after standalone switches are added to the stack, you are advised to apply for a license file that contains ESNs of all stack members before the 60-day trial period of the stack license ends.

Before installing a new license file, run the license revoke command to revoke the original license file.
