Modification

4.0(1)

This command was introduced.

Usage Guidelines

The copy command allows you to copy a file (such as a system image or configuration file) from one location to another location. The source and destination for the file is specified by using a Cisco NX-OS file system URL, which allows you to specify a local or remote file location. The file system being used (such as a local memory source or a remote server) determines the syntax used in the command.

You can enter on the command line all necessary source- and destination-URL information and the username to use, or you can enter the copy command and have the CLI prompt you for any missing information.

The entire copying process may take several minutes, depending on the network conditions and the size of the file, and differs from protocol to protocol and from network to network.

The colon character (:) is required after the file system URL prefix keywords (such as bootflash).

In the URL syntax for ftp:, scp:, sftp:, and tftp:, the server is either an IPv4 address or a hostname.

The format of the source and destination URLs varies according to the file or directory location. You can enter either a command-line interface (CLI) variable for a directory or a filename that follows the Cisco NX-OS file system syntax in this format: filesystem:[/directory][/filename].

The following tables list URL prefix keywords by the file system type. If you do not specify a URL prefix keyword, the switch looks for a file in the current directory.

Table 1 lists URL prefix keywords for local writable storage file systems. Table 2 lists the URL prefix keywords for remote file systems. Table 3 lists the URL prefix keywords for nonwritable file systems.

This command does not require a license.

Copying Files from a Server to Bootflash Memory

Use the copy source-url bootflash: command (for example, copy tftp:source-url bootflash:) to copy an image from a server to the local bootflash memory.

Copying a Configuration File from a Server to the Running Configuration

Use the copy {ftp: | scp: | sftp: | tftp:}source-url running-config command to download a configuration file from a network server to the running configuration of the device. The configuration is added to the running configuration as if the commands were typed in the CLI. The resulting configuration file is a combination of the previous running configuration and the downloaded configuration file. The downloaded configuration file has precedence over the previous running configuration.

You can copy either a host configuration file or a network configuration file. Accept the default value of host to copy and load a host configuration file containing commands that apply to one network server in particular. Enter network to copy and load a network configuration file that contains commands that apply to all network servers on a network.

Copying a Configuration File from a Server to the Startup Configuration

Use the copy {ftp: | scp: | sftp: | tftp:}source-url startup-config command to copy a configuration file from a network server to the switch startup configuration. These commands replace the startup configuration file with the copied configuration file.

Copying the Running or Startup Configuration on a Server

Use the copy running-config {ftp: | scp: | sftp: | tftp:}destination-url command to copy the current configuration file to a network server that uses FTP, SCP, SFTP, or TFTP. Use the copy startup-config {ftp: | scp: | stfp: | tftp:}destination-url command to copy the startup configuration file to a network server.

You can use the copied configuration file as a backup.

Table 1, Table 2, and Table 3, list the URL prefix keywords.

Table 1 URL Prefix Keywords for Local Writable Storage File Systems

Modification

4.2 (1)

This command was introduced.

Usage Guidelines

Follow these guidelines when you upgrade or downgrade the EPLD:

You can perform an upgrade from the active supervisor module only. All the modules, including the active supervisor module, can be updated individually.

You can individually update each module whether it is online or offline as follows:

– If you upgrade EPLD images on an online module, only the EPLD images with version numbers that differ from the new EPLD images are upgraded.

– If you upgrade EPLD images on an offline module, all of the EPLD images are upgraded.

On a switch that has two supervisor modules, upgrade the EPLDs for the standby supervisor and then switch the active supervisor to standby mode to upgrade its EPLDs (the supervisor switchover is not disruptive to traffic on Cisco Nexus 7000 switches). On a switch that has only one supervisor module, you can upgrade the active supervisor, but this will disrupt its operations during the upgrade.

If you interrupt an upgrade, you must upgrade the module that is being upgraded again.

The upgrade process disrupts traffic on the targeted module.

Do not insert or remove any modules while an EPLD upgrade is in progress.

This command does not require a license.

Examples

This example shows how to upgrade a Cisco NX-OS EPLD image:

switch# install all epld bootflash:n7000-s1-epld.4.2.1.img

This command was introduced.

Usage Guidelines

You can use the power redundancy-mode command only in the default virtual device context (VDC).

You can configure the power supplies with the following modes:

Combined mode—This is the simplest power mode, but it does not provide power redundancy. The available power for this mode is the total power capacity of all power supplies.

Power supply redundancy mode—This mode provides an extra power supply in case an active power supply goes down. With this mode, the power supply that can supply the most power operates in the standby mode. The other one or two power supplies are active. The available power is the amount of power provided by the active power supply units.

Input source redundancy mode—This mode uses two electrical grids, each one powering a half module within each power supply. If one power grid goes down, each power supply continues to draw power through its other half module. The available power is the amount of power by the lesser of the two grids through the power supplies.

Full redundancy mode—This mode combines power supply redundancy and input source redundancy, which means that the chassis has an extra power supply and each half of each power supply is connected to one electrical grid while the other half of each power supply is connected to the other electrical grid. The available power is the lesser of the available power for the power supply mode and input source mode.

This command does not require a license.

Examples

This example shows how to configure the full power supply redundancy mode:

switch# configure terminal

switch(config)# power redundancy-mode redundant

This example shows how to disable the full power supply redundancy mode:

switch# configure terminal

switch(config)# no power redundancy-mode redundant

Modification

6.2(2)

This command was introduced.

Usage Guidelines

To run CLI commands in Python, you must import the cisco module. The cisco module contains the code that integrates with the command-line interface (CLI).

The functions contained in the cisco module that enable the CLI commands are imported automatically when you use the python command to invoke the Python interactive mode (or when you use the source command when invoking the Python noninteractive mode).

The Python programming language has three APIs that can execute CLI commands. See the Cisco Nexus 7000 Series NX-OS Fundamentals Configuration Guide, Release 6.x for a list of CLI commands.

Examples

This example shows how to invoke Python from the CLI:

Note The Python interpreter is designated with the ">>>" or "..." prompt.

switch# show clock

23:54:55.872 UTC Wed May 16 2012

switch # python !-- Enter Python interpreter

switch >>> cli ("conf term ; interface loopback 1")

switch(config-if)# >>> cli("ip address 1.1.1.1/24")

switch(config-if)# >>> cli("exit") !-- Exit the CLI interface mode

switch(config)# >>> cli("exit")

switch# >>> i=0

switch# >>> while i<8:

switch# >>> i=i+1 !-- Composite command; prompt indicates more input

switch# ... cmd = "show module %i" % i

switch# ... r=clid(cmd)

switch# ... if "TABLE_modinfo/model" in r.keys():

switch# ... if r ["TABLE_modinfo/model"] == "Nurburgring":

switch# ... print "got a racer in slot %d" % i

switch# ... !-- Empty input indicates end of loop

got a racer in slot 3

switch# >>> exit !-- Exit Python interpreter

Python is forked from the CLI shell, which means the following::

No state is preserved between invocations of the Python interpreter.

The CLI mode is lost when exiting the Python interpreter.

This example shows the nonpersistence of the Python interpreter:

switch# python !-- Invoke Python interpreter

switch# >>> i = 2

switch# >>> print "var i = %d" % i

var i = 2

switch# >>> cli("configure terminal")

switch(config)# >>> blabla

switch(config)# >>> exit !-- Exit Python interpreter

switch# !-- CLI still in exec mode (conf t is lost)

switch# python !-- Invoke new Python interpreter

switch# >>> print "var i = %d" % i !-- Previous Python interpreter and variables are lost

Error: variable 'i' undefined.

switch# >>> exit

switch# conf t ; inter lo 1

switch(config-if)# python !-- Invoke new Python interpreter

switch(config-if)# >>> !-- Inherits the CLI mode (forked from CLI)
