88 CHAPTER 11: USING SWITCH CONFIGURATION FEATURES user attempts to restore a configuration that was saved by a security level user, the restore operation will fail because the security level commands are not available to the manager. A manager level user can only save a configuration that contains the commands that are available to that user level. Important Considerations ■ The Switch unit must be reset to its factory default settings before you can restore a configuration onto it. You can reset the Switch using the system control initialize CLI command or the System > Control > Initialize Web interface operation. ■ The configuration can only be restored onto a device or stack which has the same physical connections and configuration, including expansion modules, as when the configuration was initially saved. The restore operation will be unsuccessful if the physical configuration of the device or stack is different. ■ The configuration of the Switch must only be restored or saved by a single user at a time. The system summary CLI command displays the progress of restore and save operations to all other users. ■ When using the Configuration Save and Restore feature, 3Com recommends that aggregated links are configured as either: ■ Manual aggregations with Link Aggregation Configuration Protocol (LACP) disabled on the ports that are to be manually placed in the aggregated link. or ■ LACP automatic aggregations - that is, LACP enabled on all ports and the aggregated links created automatically. The aggregated link should be enabled and Spanning Tree Protocol enabled. Parameters such as VLANs and Fast Start may be set up as required. Other combinations of port settings, however, are not recommended as Configuration Restore will only perform a "best effort" restore of the configuration. For example, LACP automatic aggregations with manually defined ports are restored as manual aggregations with manual ports. LACP automatic aggregations with automatic ports where the aggregated link is disabled and Spanning Tree Protocol is disabled are restored as manual aggregations with the aggregated link disabled.
