Overview
From Cisco DCNM Release 11.4(1), the Classic LAN deployment is unsupported. If you are planning to upgrade your Classic LAN deployment to DCNM Release 11.4(1), the only available upgrade option is to the DCNM Release 11.4(1) LAN Fabric deployment, and it is done automatically during the DCNM inline upgrade process.
In the LAN Fabric deployment, there are two new fabric templates that you can use to manage your switches. For more information, see Managing Switches Using Classic LAN Templates.
The following table summarizes upgrades for your Classic LAN deployment to the Cisco DCNM Release 11.4(1):
From Classic LAN deployment in DCNM Release | To LAN Fabric deployment in DCNM Release | Upgrade |
---|---|---|
11.3(1) | 11.4(1) | Inline upgrade |
11.2(1) | 11.4(1) | Inline upgrade |
11.1(1) | 11.4(1) | Inline upgrade |
When you perform the inline upgrade from older releases to Cisco DCNM Release 11.4(1), automatic conversion to LAN Fabric mode using LAN_Classic and Fabric_Group fabric templates is done.
Note |
We recommend that you to familiarize yourself with the Cisco DCNM LAN Fabric functionalities before proceeding with the upgrade. For information, see Cisco DCNM LAN Fabric Configuration Guide, Release 11.4(1). |
Prerequisites
-
Review the Cisco DCNM 11.4(1) LAN Fabric System Requirements to ensure that your existing deployment meets those criteria. See System Requirements.
-
Review the Cisco DCNM LAN Fabric Verified Scalability section to ensure your existing deployment needs are met. See Verified Scalability Guide for Cisco DCNM.
Guidelines and Limitations
-
In the Classic LAN deployment, if you are managing switches using the in-band interfaces, upgrading to the LAN Fabric deployment is not supported. You need to change to managing switches using the management (mgmt0) interfaces, and then upgrade.
The support for in-band interface management is expected to be available in a future release.
-
VDC Auto-Provisioning (VOAP) for Cisco Nexus 7000 Series switches is not supported in the LAN Fabric installation mode.
-
The following configurations are not migrated from Classic LAN to the LAN Fabric Deployment:
-
Config archive jobs.
Post upgrade, you should configure the fabric backups from the fabric settings.
-
CLI jobs.
-
POAP DHCP configuration.
Post upgrade, you should configure the Fabric Settings for POAP.
