Configuring Generation 2 Module Interface Shared Resources Chapter 22 Configuring Generation 2 Switches and Modules Send documentation comments to [email protected] To disable bandwidth fairness on a single 48-port or 24-port 4-Gbps Fibre Channel switching module using Device Manager, follow these steps: Step 1 Step 2 Step 3 Right-click a module and select Configure. You see the Module dialog box as shown in Figure 22-11. Click the disable radio button to disable bandwidth fairness. Click Apply to save the changes. Upgrade or Downgrade Scenario When you are upgrading from a release earlier than Cisco SAN-OS Release 3.1(2), all modules operate with bandwidth fairness disabled until the next module reload. After the upgrade, any new module that is inserted has bandwidth fairness enabled. When you are downgrading to a release earlier than Cisco SAN-OS Release 3.1(2), all modules keep operating in the same bandwidth fairness configuration prior to the downgrade. After the downgrade, any new module that is inserted has bandwidth fairness disabled. Taking Interfaces Out of Service You can take interfaces out of service on Generation 2 switching modules. When an interface is out of service, all the shared resources for the interface are released as well as the configuration associated with those resources. Note The interface must be disabled before it can be taken out of service. Caution Taking interfaces out of service releases all the shared resources to ensure that they are available to other interfaces. This causes the configuration in the shared resources to revert to default when the interface is brought back into service. Also, an interface cannot come back into service unless the default shared resources for the port are available. The operation to free up shared resources from another port is disruptive. Note The interface cannot be a member of a PortChannel. To take an interface out of service using Fabric Manager, follow these steps: Step 1 Step 2 Step 3 Step 4 Select a switch from the Fabric pane, or select a group of switches (SAN, fabric, VSAN) from the Logical Domains pane. Expand Switches, expand Interfaces and select FC Physical in the Physical Attributes pane. You see the FC Physical > General tab in the Information pane. Scroll down until you see the row containing the switch and port you want to configure. Scroll right (if necessary) until you see the Status Service column. 22-28 Cisco MDS 9000 Family CLI Configuration Guide OL-16184-01, Cisco MDS SAN-OS Release 3.x
