              Fabric Domain Switch Mapping

              The first time a network is created with any mobility domain, the reference is kept, so that subsequently selecting the same switch with a different mobility domain is not allowed.

              For example, the user has a default Mobility Domain as md0 and has created several networks. In UCSD, the rule is that one switch can be mapped with one mobility domain. So, if the N1K switch was selected while creating the network, then it is mapped with the md0 Mobility Domain.

              If the user logs in to DCNM and updates the Default Mobility Domain to a different domain name, for example, Cluster_10, and then does an Inventory Collection, the UCSD is updated and the default Mobility Domain will show as Cluster_10 in the General Settings tab.

              However, the original Mobility Domain and the associated Switch Mapping will not be updated since there are networks in UCSD. Attempting to associate the same switch with another mobility domain in UCSD is not allowed until the mapping between md0 and the initial N1K association is removed. if there are networks already created in UCSD, the association will not be removed.

              The following are suggested workarounds:

              • Remove the DCNM account and re-add it into UCSD. This will not remove any networks from DCNM

              • Delete the network already created with md0 so UCSD will remove the association

              • Delete the network in DCNM that has the older Mobility association and do Inventory Collection in UCSD

              Deleting a Fabric Network

                Step 1   On the menu bar, choose Physical > Network.
                Step 2   In the left pane, click the Multi-domain Manager entry.

                          Examining the Fabric SegmentID Range

                          Each network can have an associated segment ID range. Each network has an account ID. Cisco Unified Fabric Automation assigns a segment ID range to one Orchestrator. OpenStack can also talk to Cisco Data Center Network Manager (DCNM). When Cisco UCS Director Orchestrator creates a network, it uses the segments listed in these segment ID ranges.

                            Step 1   On the menu bar, choose Physical > Network.
                            Step 2   In the left pane, click the Multi-domain Manager entry.

                            Along with the double-click, you can select the arrow button, double-click on the DCNM Account created, and see the Fabric SegmentID Range Management tab.

                            Step 4   Click the Fabric SegmentID Range Management tab. The Account Name, Orchestrator Name, and SegmentID Range are displayed.
