Cisco SME Interface Configuration


This chapter describes how to configure and start Cisco SME interfaces using Fabric Manager and Device Manager.

After completing the preliminary tasks described in Chapter 2 "Getting Started," you need to configure the Cisco SME interface on a Cisco MDS switch with an installed MSM-18/4 module or on a Cisco MDS 9222i switch.

This section contains the following topics:

Configuring and Starting the Cisco SME Interface

Configuring and Starting the Cisco SME Interface

Cisco SME interfaces are configured either by using the Device Manager or the CLI. For information about creating Cisco SME interfaces using the CLI, see Chapter 7 "Using the Command Line Interface to Configure SME."

This section describes the following:

Configuring and Starting an Cisco SME Interface Using Device Manager

Configuring and Viewing Cisco SME Interfaces in Fabric Manager

Configuring and Starting an Cisco SME Interface Using Device Manager

To configure and create an Cisco SME interface using Device Manager, follow these steps:


Step 1 Open the Device Manager for the switch that needs to have the Cisco SME interface defined.

Step 2 From the Admin menu, select Interface.

Step 3 From the Interface menu, select SME > Interfaces. This opens SME Interfaces in a new window.

Step 4 Click Create. A new SME Interfaces window opens.


Note You can only create a Cisco SME interface if there is a license on the switch available for an MSM-18/4 module. One license per MSM-18/4 module and per Cisco MDS 9222i slot 1 is required for the Cisco SME feature.


Step 5 Click the up radio button and click Create.

For a module with four interfaces, the window with Node drop-down appears. Select the node number from the pulldown menu and click Create.

The node number will become the port number. For example, for module 12 and node 2, the Device Manager creates sme12/2 interface.


Note The Node option is available only from Release 4.2(1).


Step 6 Open the Fabric Manager Web Client window to view the configured Cisco SME interfaces.


Configuring and Viewing Cisco SME Interfaces in Fabric Manager

This section covers the following topics:

Viewing Cisco SME Interfaces

To view the Cisco SME interfaces, follow these steps:


Step 1 In the Physical Attributes pane of the Fabric Manager Web Client, select End Devices > SME.

Step 2 Select Interfaces to view the information about the Cisco SME interfaces on the right-side pane. The table lists the information of upto four SME interfaces.


Note After creating the interfaces, you must first configure a Cisco SME cluster and then add the Cisco SME interfaces to the cluster. For details on configuring clusters, see Chapter 4 "Cisco SME Cluster Management."



Creating Cisco SME Interfaces

To create Cisco SME interfaces, follow these steps:


Step 1 Select End Devices > SME > Interfaces in the Physical Attributes pane.The Interfaces table appears.

Step 2 Click the Create Row... button. A new Interfaces window opens.

For a module with four interfaces, the Interfaces window with Node drop-down appears.

Step 3 Select the switch, module and port (node) number. Click Create.


Deleting Cisco SME Interfaces

To delete Cisco SME interfaces, follow these steps:


Step 1 Select End Devices > SME > Interfaces in the Physical Attributes pane. The Interfaces table appears.

Step 2 Select the interface to be deleted and click the Delete Row button to remove the interface.


Saving Your Interface Configurations

When an SME interface is deleted on one switch in a cluster and then added back, even if the saved SME configurations were the same, the SME interface will not be added back to the cluster.

When the switch is reloaded, the SME interfaces will not be added back to the cluster due to a certificate mismatch (because the SME interface was removed and then added back). You would then need to delete the SME interface and add it back and then enter the copy running-config startup-config CLI command.


Caution You must enter the copy running-config startup-config CLI command after adding or deleting interfaces or switches as described by the following scenario.

Adding Cisco SME Interfaces to a Cisco SME Configuration

Cisco SME includes an Add Interface Wizard to simplify the process of adding interfaces to an existing cluster. You can add additional interfaces when you add additional MSM-18/4 modules and Cisco MDS 9222i switches.


Caution After adding a Cisco SME interface on a switch that is not already part of the cluster, you should wait for the switch to join the cluster before attempting to add another Cisco SME interface. Adding a new switch to a cluster affects the quorum calculation of the cluster (see the "Cluster Quorum and Master Switch Election Overview" section). Adding more than one switch that is not online can shut down the Cisco SME application due to a lost quorum.


Note In the existing MDS 9000 Family platform, a module can be replaced with another module and there is no change in configuration. In Cisco SME, due to security reasons, when an MSM-18/4 module is configured as part of a cluster, it cannot be replaced with another MSM-18/4 module, otherwise, the Cisco SME interface will come up in an inactive state. The correct procedure is as follows:

Remove the Cisco SME interface from the cluster.

Replace the module.

Re-add the interface back into the cluster.

This procedure should be followed to bring a new MSM-18/4 module into the cluster.



Caution You must enter the copy running-config startup-config CLI command after adding or deleting interfaces or switches from a cluster.

To add Cisco SME interfaces to an existing Cisco SME configuration, follow these steps:


Step 1 From the SME navigation pane, click Members to display the switches and interfaces already configured in the cluster.

Step 2 Click Add to display the Add Interface Wizard.

Step 3 Select the fabrics you want to add interfaces from. Click Next.

Step 4 Select the SME interfaces that you would like to use. Click Next.

Step 5 View the interface information. Click Confirm to view the newly added interface.


Viewing Cisco SME Interface Information Using the CLI

Use the show sme interface CLI command to obtain information about the SME interface configuration and statistics.

Overlap commands - Multiple overlapping commands to the same ITL

Bad Target responses - check / errors from Target. This happens most of the time (filemark. Ili, and so on)

XIPC Task Lookup - Exchange lookup failures.

Rest are implicit

Removing (Unbinding) Cisco SME Interfaces from a Cisco SME Cluster

Removing a Cisco SME interface from a cluster means that the interface is still up but it is not bound to a cluster.

In the existing MDS 9000 Family platform, a module can be replaced with another module and there is no change in configuration. In Cisco SME, due to security reasons, when an MSM-18/4 module is configured as part of a cluster, it cannot be replaced with another MSM-18/4 module, otherwise, the Cisco SME interface will come up in an inactive state. The correct procedure is to remove the Cisco SME interface from the cluster and re-add the interface back into the cluster. This procedure should be followed to bring a new MSM-18/4 module into the cluster.


Caution You must enter the copy running-config startup-config CLI command after adding or deleting interfaces or switches from a cluster.

To remove (unbind) a Cisco SME interface from an existing Cisco SME configuration, follow these steps:


Step 1 From the SME navigation pane, click Members to display the switches and interfaces already configured in the cluster.

Step 2 Select a Cisco SME interface and click Remove.

Step 3 Click OK to delete (unbind) the interface.

Step 4 View the notification that the interface was removed.


Note The interface is removed while the node remains defined.



Deleting Switches From a Cisco SME Cluster


Note If the cluster includes more than one switch, you must delete all non-master switches first. It is not possible to delete the master switch from a cluster without first deleting all non-master switches.


To delete a switch from a cluster, follow these steps:


Step 1 Click Members to display the switches that are part of the cluster.

Step 2 Select the switch and click Remove.

Step 3 Click OK to delete the switch.

Step 4 View the notification that the switch was deleted.


Note The interface and the node are both removed.
