Q&A
Q. I purchased an ISSU license for a Cisco Catalyst 4500 in the past. Do I get a refund?
A. No. ISSU license removal only applies to products purchased February 1, 2011 and beyond.
Q. I purchased a Cisco Catalyst 4500 in the past and did not purchase an ISSU license. Can I activate the ISSU feature now?
A. Yes. You can activate the ISSU feature now as long as you are using IP Base or Enterprise Service image.
Q. I have LAN Base image running on one of my Cisco Catalyst 4500 switches. Can I activate the ISSU feature?
A. No. LAN Base image does not support ISSU or NSF/SSO (Nonstop Forwarding with Stateful Switchover) you need to upgrade software image to IP Base or Enterprise Services to enable ISSU or NSF/SSO. Tables 2 and 3 give the product numbers required for upgrading from LAN Base image.
