Default Settings Chapter 34 Managing FLOGI, Name Server, FDMI, and RSCN Databases Send documentation comments to [email protected] Note Before performing a downgrade, make sure that you revert the RCSN timer value in your network to the default value. Failure to do so will disable the links across your VSANs and other devices. Compatibility across various Cisco MDS NX-OS releases during an upgrade or downgrade is supported by conf-check provided by CFS. If you attempt to downgrade from Cisco MDS SAN-OS Release 3.0, you are prompted with a conf-check warning. You are required to disable RSCN timer distribution support before you downgrade. By default, the RSCN timer distribution capability is disabled and is therefore compatible when upgrading from any Cisco MDS SAN-OS release earlier than Release 3.0. Configuring the RSCN Timer with CFS To configure the RSCN timer with CFS using Fabric Manager, follow these steps: Step 1 Step 2 Expand a fabric, expand a VSAN and then select Advanced in the Logical Domains pane. Select the RSCN Event tab. You see the VSAN advanced configuration in the Information pane shown in Figure 34-6. Figure 34-6 VSAN Advanced Configuration Step 3 Double-click the TimeOut value to change the value (in milliseconds) for the selected VSAN. Step 4 Click Apply Changes to save these changes, or click Undo Changes to cancel any unsaved changes.
