● -g—Gets the specified file from the TFTP server and copies it to the local host
● -r <remote_file>—Specifies the name of the configuration file that you want to retrieve from the
TFTP server
● -l <local_file>—Specifies the name of the configuration file on the switch
If you download a configuration file and see the following message:
Error: Transfer timed out
Check to 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.
Synchronizing MSMs—Modular Switches Only
On a dual MSM system, you can take the primary MSM configurations and images and replicate them
on the backup MSM using the following command:
synchronize
CAUTION
During a synchronization, half of the switch fabric is lost. When the primary MSM finishes replicating its
configurations and images to the backup MSM, the full switch fabric is restored.
In addition to replicating the configuration settings and images, this command also replicates which
configuration or image the MSM 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 BlackDiamond 8800 Family of
Switches Only
On the BlackDiamond 8800 family of switches (formerly known as Aspen), 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.
