In-Order Delivery Chapter 32 Configuring Fibre Channel Routing Services and Protocols Send documentation comments to [email protected] Enabling In-Order Delivery Globally To ensure that the in-order delivery parameters are uniform across all VSANs on an MDS switch, enable in-order delivery globally. Only enable in-order delivery globally if this is a requirement across your entire fabric. Otherwise, enable IOD only for the VSANs that require this feature. Note Enable in-order delivery on the entire switch before performing a downgrade to Cisco MDS SAN-OS Release1.3(3) or earlier. Enabling In-Order Delivery for a VSAN When you create a VSAN, that VSAN automatically inherits the global in-order-guarantee value. You can override this global value by enabling or disabling in-order-guarantee for the new VSAN. To use the lowest domain switch for the multicast tree computation using Fabric Manager, follow these steps: Step 1 Step 2 Expand a fabric and select All VSANS. Select the Attributes tab. You see the general VSAN attributes in the Information pane shown in Figure 32-15. Figure 32-15 General VSAN Attributes Step 3 Check the InOrder Delivery check box to enable IOD for the switch. Step 4 Click Apply Changes to save these changes, or click Undo Changes to discard any unsaved changes. Configuring the Drop Latency Time You can change the default latency time for either the entire switch or a specified VSAN in a switch. To configure the drop latency time for a switch using Fabric Manager, follow these steps: 32-18 Cisco MDS 9000 Family CLI Configuration Guide OL-16184-01, Cisco MDS SAN-OS Release 3.x
