По моему все предельно ясно:

Issue the write net command in order to store the running configuration in the TFTP server.

The write net command is equivalent to the copy running-config tftp command.

    write net :

The running configuration is the configuration that currently runs in memory. This includes any changes you made at the command line. In multiple context mode, this command saves only the current configuration. You cannot save all contexts with a single command. This command must be entered separately for the system and for each context.

The write net command uses the context interfaces to write a configuration to a TFTP server. However, the write memory command uses the admin context interfaces in order to save to the startup configuration because the system uses the admin context interfaces to access context startup configurations.

This example sets the TFTP server and filename in the tftp-server command.

    hostname#tftp-server inside 10.1.1.1 /configs/contextbackup.cfg

    hostname#write net

This example sets the server and filename in the write net command. The tftp-server command is not populated.

    hostname#write net 10.1.1.1:/configs/contextbackup.cfg

Note: If you have a PIX Firewall configuration that exists on a TFTP server and store a shorter version of that configuration with the same filename on the TFTP server, you might notice extra text after the first :end mark.. Some TFTP servers begin to write at the start of the file and thus leave some of the original configuration after the first :end mark. This does not affect the PIX Firewall. However, because the configure net command stops reading when it reaches the first :end mark, such a situation might cause confusion if you view the configuration and see extra text at the end.
