|
|
---|---|
4.0(0)N1(1a) |
This command was introduced. |
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 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.
Format of Source and Destination URL
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 (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 router looks for a file in the current directory.
Table 1-1 lists URL prefix keywords for local writable storage file systems. Table 1-2 lists the URL prefix keywords for remote file systems. Table 1-3 lists the URL prefix keywords for nonwritable file systems.
This section contains usage guidelines for the following topics:
•Copying Files from a Server to Bootflash Memory
•Copying a Configuration File from a Server to the Running Configuration
•Copying a Configuration File from a Server to the Startup Configuration
•Copying the Running or Startup Configuration on a Server
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 router 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 copy as a backup.
This example shows how to copy a file within the same directory:
switch# copy file1 file2
This example shows how to copy a file to another directory:
switch# copy file1 my-scripts/file2
This example shows how to copy a file to another file system:

You cannot enable or disable LLDP on a Cisco Nexus 5000 Series switch. LLDP is enabled on the switch by default. However, the feature lldp command shows as part of the running configuration on the switch.
The Cisco Discovery Protocol (CDP) is a device discovery protocol that runs over Layer 2 (the data link layer) on all Cisco-manufactured devices (routers, bridges, access servers, and switches). CDP allows network management applications to automatically discover and learn about other Cisco devices connected to the network.
To support non-Cisco devices and to allow for interoperability between other devices, the switch supports the Link Layer Discovery Protocol (LLDP). LLDP is a neighbor discovery protocol that is used for network devices to advertise information about themselves to other devices on the network. This protocol runs over the data-link layer, which allows two systems running different network layer protocols to learn about each other.
This example shows how to enable LLDP on the switch:
switch(config)# feature lldp
switch(config)#
This example shows how to disable LLDP on the switch:
switch(config)# no feature lldp

|
|
---|---|
4.0(0)N1(1a) |

switch# configure terminal switch(config)# hostname Engineering2 Engineering2(config)#
This example shows how to revert to the default hostname:

To install the kickstart and system images on a Cisco Nexus 5000 Series switch, use the install all command.
install all [kickstart kickstart-url] [system system-url]
If you do not enter any parameters, the boot variable values are used.
EXEC mode
|
|
---|---|
4.0(0)N1(1a) |
This command was introduced. |
The format of the kickstart and system URLs varies according to the file system, directory, and file location.
The following tables list URL prefix keywords by the file system type. If you do not specify a URL prefix keyword, the router looks for a file in the current directory.
Table 1-4 lists URL prefix keywords for local writable storage file systems. Table 1-5 lists the URL prefix keywords for remote file systems. For remote file systems, if it is not otherwise specified, the path is the default for the user on the remote server.
If you do not enter the information about the server or username when downloading and installing the image files from a remote server, you are prompted for the information.
This command sets the kickstart and system boot variables and copies the image files to the redundant supervisor module.
The install all command upgrades the switch software and also upgrades the Fabric Extender software of all attached chassis. The Fabric Extender remains online passing traffic while the software is copied. Once the software images have successfully been installed, the parent switch and the Fabric Extender chassis are rebooted automatically to maintain the software version compatibility between the parent switch and the Fabric Extender.
You can use the install all command to downgrade the Cisco NX-OS software on the switch. To determine if the downgrade software is compatible with the current configuration on the switch, use the show incompatibility system command and resolve any configuration incompatibilities.
This example shows how to install the Cisco NX-OS software from the bootflash: directory:
switch# install all kickstart bootflash:nx-os_kick.bin system bootflash:nx-os_sys.bin
This example shows how to install the Cisco NX-OS software using the values configured in the kickstart and system boot variables:
switch# configure terminal switch(config)# boot kickstart bootflash:nx-os_kick.bin switch(config)# boot system bootflash:nx-os_sys.bin switch(config)# exit switch# copy running-config startup-config switch# install all
This example shows how to install the Cisco NX-OS software from an SCP server:
switch# install all kickstart scp://adminuser@192.168.1.1/nx-os_kick.bin system bootflash:scp://adminuser@192.168.1.1/nx-os_sys.bin
To install a license, use the install license command.
install license [filesystem:] [//server/] [directory] src-filename [target-filename]
Note There can be no spaces in the filesystem://server/directory/filename string. Individual elements of this string are separated by colons (:) and slashes (/).
All licenses for the Cisco Nexus 5000 Series switches are factory installed. Manual installation is not required.

---|---|
4.0(0)N1(1a) |

The output from the show tech-support command is very long. To better manage this output, you can redirect the output to a file (for example, show tech-support > filename) in the local writable storage file system or the remote file system.
You can use one of the following redirection methods:
•> filename—Redirects the output to a file.
•>> filename—Redirects the output to a file in append mode.
