NETGEAR 8800 User Manual • You have received the new software image from NETGEAR named NG8800-11.4.0.12.xos. • You do not know your selected or booted partitions. • You are currently using the primary partition. • The image is on a TFTP server named tftphost. • You are installing the new image immediately after download. • The MSM installed in slot A is the primary. • The MSM installed in slot B is the backup. • You are running XCM8800 11.4 or later on both MSMs. Performing a Hitless Upgrade on the Alternate Partition The following example shows the commands necessary to perform a hitless upgrade on the alternate partition. In this example, the secondary partition is the inactive partition: show switch download image tftphost NG8800-11.4.0.12.xos secondary show switch reboot msm B show switch run msm-failover show switch After executing these commands, MSM B will be the master, and the secondary partition will be the active partition for both MSMs. The previously running software will reside on the inactive partition (now, the primary partition). Configuration Changes The configuration is the customized set of parameters that you have selected to run on the switch. As you make configuration changes, the new settings are stored in run-time memory. Settings that are stored in run-time memory are not retained by the switch when the switch is rebooted. To retain the settings and have them loaded when you reboot the switch, you must save the configuration to nonvolatile storage. The switch can store multiple user-defined configuration files, each with its own filename. By default, the switch has two prenamed configurations: a primary and a secondary configuration. When you save configuration changes, you can select to which configuration you want the changes saved or you can save the changes to a new configuration file. If you do not specify a filename, the changes are saved to the configuration file currently in use. Or if you have never saved any configurations, you are asked to save your changes to the primary configuration. Appendix B. Software Upgrade and Boot Options | 817
