Chapter 3 Cisco SME Interface Configuration

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 on page 4-30). 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.
