These two fully functioning <strong>4500</strong>s in<br />
VSS mode are actually running 2<br />
different versions of code. But these<br />
images are ISSU compatible.<br />
*** Do not attempt ISSU unless you<br />
are certain that the two images can coexist<br />
in a VSS platform, and are ISSUcapable.<br />
The current state in this example is<br />
that the standby has just completed an<br />
in-service loadversion upgrade from<br />
“SG511” to the “SG522” image, has<br />
reloaded, and is back in service.*<br />
