Log in

Indicates things to keep in mind regarding IPv4 and IPv6 addressing.


Understand these points about Catalyst Center and IPv4/IPv6 addressing:

  • Catalyst Center does not support dual stack addressing, which is the simultaneous use of both IPv4 and IPv6 addressing.

  • To switch from one addressing scheme to the other, you must Reimage the appliance.

  • You cannot restore a backup file from an appliance that uses IPv4 to an appliance that uses IPv6, or vice versa.

  • If your appliance uses IPv6 addressing, see the "IPv6 Limitations" section in the Release Notes for Cisco Catalyst Center for a description of the features that are not supported.


Password considerations


VLAN mode considerations

Consider these details about VLAN mode:

  • For a description of VLAN mode, refer to Configure the primary node using the Maglev wizard.

  • VLAN mode:

    • Can only be enabled when you configure a Catalyst Center appliance using the Maglev Configuration wizard.

    • Cannot be enabled using any of the browser-based configuration wizards.

    • Cannot be disabled without reimaging the appliance.

  • Disaster recovery is not supported by Catalyst Center deployments that have VLAN mode enabled.
