Virtual Chassis - ISSU<br />

Configuring Virtual Chassis<br />

2 Create the flash/issu_dir directory and copy the image files, the issu_version file, the vcsetup.cfg, and<br />

vcboot.cfg files to the /flash/issu_dir directory.<br />

3 Enter ‘issu from issu_dir’ to begin the ISSU upgrade.<br />

4 The Master copies the /flash/issu_dir directory to the Slave chassis, the Slave is reloaded with the<br />

upgraded code and rejoins the Virtual Chassis.<br />

5 The Master chassis is now reloaded with the upgraded code which causes the Slave chassis to become<br />

the new Master chassis.<br />

As a result of this process all chassis are now running with the upgraded code and the Master and Slave<br />

chassis will have changed roles.<br />

6 Enter ‘copy running certified flash-synchro’ to certify the configuration.<br />

7 Enter ‘reload chassis-id 2’ to have the original Master resume its Master role.<br />
