## Adding SME Interfaces to a SME Configuration

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 Cisco MSM-18/4 modules, SSN-16 modules, and Cisco MDS 9222i switches.

Note You must enter the copy running-config startup-config CLI command after adding or deleting interfaces or switches.

Restrictions

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

Detailed Steps

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

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

2. Click Add to display the Add Interface Wizard.

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

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

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