Appendix A Upgrading From Cisco IAC 4.1 to 4.1.1
Upgrading and Sub-Interface Support
Existing Organizations, Before Upgrade
• New networks added to existing Virtual Data Centers (VDCs) as well as new VDCs will use physical
interface creation. (Only if upgrading from 4.0 patch 4.)
• Decommissioning of existing VDCs works as expected and is not affected by the upgrade.
Newly-Created Organizations, After Upgrade
• Newly created VDCs, as well as networks added to the new VDCs, will use sub-interface creation.
Note Only new Organizations support sub-interface creation. New VDCs and new networks within these
VDCs that belong to new organizations will use the sub-interface creation functionality. New VDCs and
their networks created in existing Organizations do not support sub-interfaces and will continue to use
physical interface creation.
Upgrading CSR and Sub-Interfaces Support
When deploying Cloud Services Routers (CSRs) from version 3.12 to CSR version 3.1.3, we expect the
following behavior:
• Existing organizations with CSR 3.12 will not be affected by the Cisco IAC upgrade nor by the CSR
upgrade and will continue to use only physical interfaces.
