This command has two parameters, S2700-26TP-EI-DC S2700-26TP-EI-DC the first parameter represents the source location configuration file, which need to be copied files. The second parameter that target position, that is to copy the configuration files to which place. Such as the use of the copy running-config TFTP command, you can run the configuration file is copied to the TFTP server on the network to configure.

But in the copy, the need to pay attention to, if the target location with the same profile, this command will configuration file the same name in the object file is overwritten. But this saying it is easy, but difficult to do. Specifically, need to do the following.

First, when the change operation switch configuration files in RAM, will need to run configuration file of the latest backup. This is mainly because the contents of power RAM in memory will be lost after the. If the network administrator wants to change in the operation of the switch process, is still valid when the switch the next reboot.

It will this ...
... change the content stored in the startup configuration file. If you want to achieve this purpose, can use the command copy running-config startup-config. This command is the meaning of the run configuration file to start the switch configuration file. If so, it will switch the recently updated content preserved.

Secondly, need to pay attention to is, in the run configuration file in RAM are copied into NVRAM, need to ensure the accuracy of the current configuration. That is to say, when we modify the run configuration file in RAM related parameters, generally will not rush to the relevant content is copied to the NVRAM.

But the need to test and track them, to determine the parameters of the new setting is consistent with the expected demand. It is to determine whether the new parameters play a role, whether to meet the needs of users. Only to ensure that the new configuration of the parameters under normal operation, can this update will be saved to the startup configuration file.

Otherwise, if the parameter settings are wrong, then there may be a problem when the next reboot. For the sake of safety, the best in the run configuration file is copied to the NVRAM, to make a backup of the NVRAM content.

This is mainly because when using copy running-config startup-config command, the command will startup configuration file automatic target position. If the run configuration file is wrong, then even the gods is irretrievabl. Therefore the author established a network administrator, when managing configuration file, be careful and cautious, would rather walk one more step.

As in the save changes before, the original boot configuration file on the TFTP server backup a. So, even though the recent allocation problem, and the network administrator and save it, can also start switch using configuration file backup.

To achieve this function, the network administrator can run the command copy start TFTP (the startup configuration file to the TFTP server). If there is a problem with the startup configuration file, you can also use the copy TFTP start command to copy the configuration files, backup to NVRAM, so that the switch to use the configuration file to initialize.

Third, in addition to the reciprocal replication between NVRAM and TFTP server, between the RAM and the TFTP server can also be mutual copy. Such as the network administrator to update a switch configuration file parameters, such as setting up virtual local area network.

This may be in a short time is difficult to judge whether the current configuration is accurate. You may need to run a week or even longer can judge. It is best to not easy to update the boot configuration file content. The author proposes methods is to copy the run configuration file in RAM to the TFTP server, the realization of a temporary transition.

When determining the configuration is not the problem, then the run configuration file replication, replace the startup configuration file, to save the latest updates available. To achieve this demand, you can use the command copy run TFTP (the run configuration file is copied to the TFTP server) or use the command copy TFTP run (copy the configuration file on the TFTP server to the ram.) these two commands to achieve.

The best again, relates to how to configure a run configuration file or the initial parameter file to a lot of content, it is very difficult. But if the configuration file, the copy command is the core. Use this command to the key, is before the switch configuration file to make any changes, backup. And after that the updated content is available, and save it to power is not easy to be lost S2700-52P-EI-AC S2700-52P-EI-AC in NVRAM or network TFTP server.
