## SME Configuration Practices

• Troubleshoot any new configuration changes after implementing the change.

• Save all configuration changes on all switches in the cluster for correct cluster operation.

• When designing your backup environment, consider that Cisco SAN-OS or NX-OS supports one cluster per switch.

• For configuration changes to SME tape groups, it is recommended that the backup application is quiesced during the configuration change.

• Refer to the Cisco Storage Media Encryption Design Guide for guidelines on sizing and placements of SME interfaces.
