NETGEAR 8800 User Manual Make sure that you entered the filename correctly, including the .cfg extension, and that you entered the correct host name or IP address for the TFTP server. If your download is successful, the switch displays a message similar to the following: Downloading megtest2.cfg to switch... done! Configurations are downloaded and saved into the switch nonvolatile memory. The configuration is applied after you reboot the switch. If the configuration currently running in the switch does not match the configuration that the switch used when it originally booted, an asterisk (*) appears before the command line prompt when using the CLI. You can also download the current configuration in ASCII format from a TFTP server on your network to the switch. For more information, see ASCII-Formatted Configuration Files on page 819. Synchronizing Nodes on Modular Switches On a dual MSM system with redundancy, you can take the primary node configurations and images and replicate them on the backup node using the following command: synchronize CAUTION: During a synchronization on a modular chassis, half of the switch fabric is lost. When the primary node finishes replicating its configurations and images to the backup node, the full switch fabric is restored. In addition to replicating the configuration settings and images, this command also replicates which configuration or image the node should use on subsequent reboots. This command does not replicate the run-time configuration. You must use the save configuration command to store the run-time configuration first. Additional Behavior on the NETGEAR 8800 Series Switches On the NETGEAR 8800 series switches, the I/O ports on the backup MSM go down when you synchronize the MSMs. When the primary MSM finishes replicating its configurations and images to the backup MSM, the I/O ports on the backup MSM come back up. Automatic Synchronization of Configuration Files On a dual MSM/MM (node) modular chassis where redundancy is in use, XCM8800 automatically synchronizes all of the configuration files from the primary node to the backup node if the switch detects that the backup node's configuration file contents are different from the primary node. You do not configure this behavior. Appendix B. Software Upgrade and Boot Options | 825
