Impact of change in FQDN and IP address on the Geographic Redundancy feature

Last Updated : Nov 30, 2021 |

In a Geographic Redundancy configuration, the system automatically communicates any change in the IP address or FQDN of the primary or the secondary System Manager to the elements.

Impact of the change in IP address or FQDN on the primary System Manager

  • The system changes the identity certificates of the primary System Manager. Therefore, reinitialize trust on the primary System Manager.

  • The secondary System Manager does not require any trust changes.

  • System Manager notifies the change to the elements. If the event notification fails due to a temporary disconnect, the system sends the event when the elements resume the network connectivity.

Impact of the change in IP address or FQDN on the secondary System Manager in the active and stand-by modes

  • The system changes the identity certificates of the secondary System Manager. Therefore, reinitialize trust on the secondary System Manager.

  • The primary System Manager does not require any trust changes.

  • System Manager notifies the change to the elements. If the event notification fails due to a temporary disconnect, the system sends the event when the elements resume the network connectivity.

Impact of the change in IP address or FQDN during a network split

When the split network heals, run the IPFQDN pair.
