Use this command to set the boot variable to flash:packages. Use this command to verify the boot variable is set to flash:packages.

Use this command to install the target image to flash. We recommend copying the image to a TFTP server or the flash drive of the active switch. If you point to an image on the flash or USB drive of a member switch instead of the active , you must specify the exact flash or USB drive - otherwise installation fails.

After you have successfully installed the software, use this command to verify that the flash partition has five new. See sample output below:. If you copied the file to flash, use this command to check if it is still saved in the the flash of each switch.

If an image is still saved, use this command to delete it, if not, it has been deleted as part of the install operation and you can skip this step. If the switch is configured with auto boot, then the stack automatically boots up with the new image. Note that you can use this procedure for the following upgrade and downgrade scenarios:. The sample output covers an upgrade scenario; the same steps apply when you downgrade as well.

Use the switch all option to upgrade or downgrade all the switches in your stack. Use this command to confirm that the image has been successfully copied to flash. After you have successfully installed the software, verify that the flash partition has five new. You can point to the source image on your tftpserver or in flash if you have it copied to flash. Use this command with the new option, to downgrade your stack. Use the switch all option to downgrade all the switches in your stack.

The old files listed in the logs should be removed using the software clean command, after reload. Use this command to delete the file from flash of each switch if you copied it to flash.

Use this command to ensure you have enough space in flash to expand a new image by cleaning up old installation files. Use this command to manually boot flash:packages. Use this command to delete the file from the flash of each switch if you had copied to flash. This section provides information about the licensing packages for features available on Cisco Catalyst Series Switches. The software features available on Cisco Catalyst Series Switches fall under these base or add-on license levels.

The license supports up to VLANs. To find information about platform support and to know which license levels a feature is available with, use Cisco Feature Navigator. An account on cisco. A switch stack cannot contain mixed license levels. Also, the switches must be of the same platform. Evaluation licenses cannot be ordered. They are not tracked via Cisco Smart Software Manager and expire after a day period.

Evaluation licenses can be used only once on the switch and cannot be regenerated. Warning system messages about an evaluation license expiry are generated only days after expiration and every week thereafter. An expired evaluation license cannot be reactivated after reload.

Cisco Smart Licensing is a flexible licensing model that provides you with an easier, faster, and more consistent way to purchase and manage software across the Cisco portfolio and across your organization.

With Smart Licensing you get:.

Begin by establishing a connection from your network to Cisco Smart Software Manager on cisco.

Only authorized users can activate the Smart Account. Set up the required number of Virtual Accounts, users and access rights for the virtual account users. Virtual accounts help you organize licenses by business unit, product type, IT group, and so on.

For Cisco Catalyst Series Switches , after you have upgraded the software image and deployed Smart Licensing, all traditional licenses on the device must be migrated, to Cisco Smart Software Manager. This is a one-time migration process that you must complete on each device. Generate the registration token in the Cisco Smart Software Manager portal and register your device with the token. Note how upgrading to a release that supports Smart Licensing or moving to a release that does not support Smart Licensing affects licenses on a device:.

When you upgrade from an earlier release to one that supports Smart Licensing —all existing licenses remain in evaluation mode until registered in Cisco Smart Software Manager and then converted. After conversion, they are made available in your Smart Account. When you downgrade to a release where Smart Licensing is not supported —all smart licenses on the device are converted to traditional licenses and all smart licensing information on the device is removed.

Cisco TrustSec can be configured only on physical interfaces, not on logical interfaces.

These features are introduced on the Web UI in this release. LAN Base. When you enter the configure replace command, the running configuration is compared with the specified replacement configuration, and a set of configuration differences is generated.

The resulting differences are used to replace the configuration. The configuration replacement operation is usually completed in no more than three passes. To prevent looping behavior no more than five passes are performed. You can use the copy source-url running-config privileged EXEC command to copy a stored configuration file to the running configuration.

When using this command as an alternative to the configure replace target-url privileged EXEC command, note these major differences:. This command does not remove commands from the running configuration that are not present in the source file.

In contrast, the configure replace target-url command removes commands from the running configuration that are not present in the replacement file and adds commands to the running configuration that are not present. You must use a complete configuration file as the replacement file for the configure replace target-url command.

You can also use the configure replace command to roll back changes that were made since the previous configuration was saved. Instead of basing the rollback operation on a specific set of changes that were applied, the configuration rollback capability reverts to a specific configuration based on a saved configuration file.

If you want the configuration rollback capability, you must first save the running configuration before making any configuration changes. Then, after entering configuration changes, you can use that saved configuration file to roll back the changes by using the configure replace target-url command. You can specify any saved configuration file as the rollback configuration. You are not limited to a fixed number of rollbacks, as is the case in some rollback models. Follow these guidelines when configuring and performing configuration replacement and rollback:.

Otherwise, the configuration replacement operation fails. The replacement file must be a complete configuration generated by a Cisco IOS device for example, a configuration generated by the copy running-config destination-url command.

Note If you generate the replacement configuration file externally, it must comply with the format of files generated by Cisco IOS devices. Using the configure replace command with the configuration archive and with the archive config command is optional but offers significant benefit for configuration rollback scenarios.

Before using the archive config command , you must first configure the configuration archive. Starting in privileged EXEC mode, follow these steps to configure the configuration archive:. Specifies the location and filename prefix for the files in the configuration archive. Optional Sets the maximum number of archive files of the running configuration to be saved in the configuration archive.

Valid values are from 1 to The default is Note Before using this command, you must first enter the path archive configuration command to specify the location and filename prefix for the files in the configuration archive. Optional Sets the time increment for automatically saving an archive file of the running configuration in the configuration archive. Starting in privileged EXEC mode, follow these steps to replace the running configuration file with a saved configuration file:.

Note Enter the path archive configuration command before using this command. The total number of passes also appears. If you do not enter the configure confirm command within the specified time limit, the configuration replacement operation is automatically stopped. In other words, the running configuration file is restored to the configuration that existed before you entered the configure replace command. Note You must first enable the configuration archive before you can use the time seconds command line option.

Optional Confirms replacement of the running configuration with a saved configuration file. Note Use this command only if the time seconds keyword and argument of the configure replace command are specified. This section describes how to download, upload, and install Cisco IOS XE software bundle files, which contain the system software packages.

You can use this uploaded bundle for future downloads to the same switch or to another switch of the same type. You can install the package files on the switch or you can boot the switch from the IOS XE bundle itself.

To display information about the provisioning software that is currently running on the switch, use the show version privileged EXEC command. In the display, check the line that begins with. System bundle file is When the switch is running in installed mode, this line displays the name and location of the booted Cisco IOS XE provisioning file, typically flash:packages.

When the switch is running in bundle mode, this line displays the name and location of the booted Cisco IOS XE bundle file. When the switch is running in installed mode, this command displays information about the set of package files contained in the booted provisioning file. When the switch is running in bundle mode, this command displays information about the set of package files contained in the booted Cisco IOS XE software bundle.

You can upload a Cisco IOS XE bundle file to a network server for backup purposes; the uploaded bundle can be used for future downloads to the same or another switch of the same type.

Directory and bundle names are case sensitive. You can upload a bundle file from the switch to a TFTP server. You can later download this bundle to the switch or to another switch of the same type. Directory and bundle file names are case sensitive.

You can later download this bundle to the same switch or to another switch of the same type. These must be associated with an account on the FTP server. For the RCP copy request to execute successfully, an account must be defined on the network server for the remote username. You can upload a software bundle file from the switch to an RCP server. The method that you use to upgrade Cisco IOS XE software depends on whether the switch is running in installed mode or in bundle mode.

To upgrade the Cisco IOS XE software when the switch is running in installed mode, use the software install privileged EXEC command to install the packages from a new software bundle file. The software install command expands the package files from the specified source bundle file and copies them to the local flash: storage device.

When the source bundle is specified as a tftp: or ftp: URL, the bundle file is first downloaded into the switch's memory RAM ; the bundle file is not copied to local storage media. After the package files are expanded and copied to flash: the running provisioning file flash:packages. Note The software install command is not supported when the switch is running in bundle mode. Use the software expand privileged EXEC command to convert the switch from bundle mode to installed mode.

Download the bundle file to local storage media. Configure the boot system global configuration command to point to the bundle file. Reload the switch. It shows using the copy command to copy the bundle file to flash:, configuring the boot system variable to point to the bundle file, saving a copy of the running configuration, and finally, reloading the switch. To convert the running mode of a switch from bundle mode to installed mode, use the software expand running privileged EXEC command.

This command expands the packages from the booted IOS XE software bundle and copies them and the provisioning file to the specified to destination. When you use the software expand running command to convert the switch from bundle mode to installed mode, specify the to destination as f lash:. After you execute the command, configure the boot system command to point to the expanded provisioning file flash:packages.

Note The software expand running command is not supported when the switch is running in installed mode. This example shows using the software expand running command to convert the active switch in a switch stack from the bundle running mode to the installed running mode:. For switch stacks running in installed mode, use the software install source switch privileged EXEC command to install the running software packages from an existing stack member to one or more other stack members that are running different but compatible software packages.

This example shows a 2-member stack where each switch is running a different but compatible software packages. The s oftware install source switch command is used to install the packages that are currently running on the standby switch switch 1 onto the active switch switch 2. For switch stacks running in bundle mode, follow these steps to copy the bundle file from one stack member to another:.

Use the copy privileged EXEC command to copy the running bundle from one switch in the stack to the other.

To upgrade a switch that is running in installed mode with software packages that are incompatible with the switch stack also running in installed mode , use the software auto-upgrade privileged EXEC command to install the software packages from an existing stack member to the stack member that is running incompatible software. Upon completion of the auto-upgrade installation, the incompatible switch automatically reloads and joins the stack as a fully functioning member.

Note If you configure the global software auto-upgrade enable command, the auto-upgrade functionality is initiated automatically when a switch with incompatible software running in installed mode joins the stack that is running in installed mode.

This example shows a 2-member switch stack; switch 2 is the active switch and switch 1 is running incompatible software. To upgrade a switch that is running in bundle mode with a software bundle that is incompatible with the switch stack also running in bundle mode , follow these steps:.

This example shows a 2-member switch stack running in bundle mode; switch 2 is the active switch and switch 1 is running an incompatible bundle. When a switch running in bundle mode tries to join a stack running in installed mode, use the software auto-upgrade privileged EXEC command to install the incompatible switch's running packages and convert the switch to installed mode.

Upon completion of the auto-upgrade running mode conversion, the incompatible switch automatically reloads and attempts to join the stack in installed mode. This example shows a 2-member switch stack running in installed mode. Switch 2 is the active switch and switch 1 is running in bundle mode. Note When you use the software auto-upgrade command to convert an incompatible switch to installed mode, the command installs the packages from the incompatible switch's running bundle.

If, after you reload and boot the incompatible switch in installed mode, the switch's installed packages are found to be incompatible with the stack, you can use the s oftware auto-upgrade command again. To convert a switch that is running in installed mode and joining a stack that is running in bundle mode, follow these steps:. After reloading, the incompatible switch boots in bundle mode and joins the stack as a fully functioning member. This example shows a 2-member switch stack running in bundle mode; switch 2 is the active switch and switch 1 is running in installed mode:.

Type Type of file system. Flags Permission for file system. Prefixes Alias for file system. Setting the Default File System You can specify the file system or directory that the system uses as the default file system by using the cd filesystem: privileged EXEC command. By default, the default file system is flash:. Displaying Information about Files on a File System You can view a list of the contents of a file system before manipulating its contents. Step 3 pwd Example: Switch pwd Displays the working directory.

Step 3 dir filesystem : Example: Switch dir flash: Verifies your entry. Caution When files and directories are deleted, their contents cannot be recovered. Copying Files To copy a file from a source to a destination, use the copy source-url destination-url privileged EXEC command.

Deleting Files When you no longer need files on a flash memory device, you can permanently delete them. Caution When files are deleted, their contents cannot be recovered. Step 2 yes or no Specifies that the listed files be deleted.

This example shows how to use the command to delete unused files on each switch in a two-switch stack: Stack software clean Preparing clean operation Deleting it may cause system instability and may prevent the system from booting on the next reload.

Creating, Displaying, and Extracting Files You can create a file and write files into it, list the files in a file, and extract the files from a file as described in the next sections. Configuration File Types and Location Startup configuration files are used during system startup to configure the software. Creating a Configuration File By Using a Text Editor When creating a configuration file, you must list commands logically so that the system can respond appropriately.

This is one method of creating a configuration file: Step 1 Copy an existing configuration from a switch to a server. For more information, see the documentation for your FTP server. Switch configure terminal Switch config ip ftp username netadmin1 Switch config ip ftp password mypass Switch config end Switch copy ftp: nvram:startup-config Address of remote host [ Step 2 ip ftp username username Example: Switch confg ip ftp username NetAdmin1 Optional Changes the default remote username.

Step 3 ip ftp password password Example: Switch confg ip ftp password adminpassword Optional Changes the default password. Write file switch2-confg on host For example, suppose that the switch contains these configuration lines: hostname Switch1 ip rcmd remote-username User0 If the switch IP address translates to Switch1. This step is required only if you override the default remote username. Step 2 ip rcmd remote-username username Example: Switch config ip rcmd remote-username netadmin1 Optional Specifies the remote username.

Clearing the Startup Configuration File To clear the contents of your startup configuration, use the erase nvram: or the erase startup-config privileged EXEC command. Caution You cannot restore the startup configuration file after it has been deleted.

Caution You cannot restore a file after it has been deleted. Replacing and Rolling Back Configurations The configuration replacement and rollback feature replaces the running configuration with any saved Cisco IOS configuration file. Replacing a Configuration The configure replace privileged EXEC command replaces the running configuration with any saved configuration file. Rolling Back a Configuration You can also use the configure replace command to roll back changes that were made since the previous configuration was saved.

Configuring the Configuration Archive Using the configure replace command with the configuration archive and with the archive config command is optional but offers significant benefit for configuration rollback scenarios. Starting in privileged EXEC mode, follow these steps to configure the configuration archive: Command Purpose Step 1 configure terminal Example: Switch configure terminal Enters global configuration mode.

Step 2 archive Example: Switch config archive Enters archive configuration mode. Step 3 path url Example: Switch config-archive path flash:myconfiguration Specifies the location and filename prefix for the files in the configuration archive. Step 4 maximum number Example: Switch config-archive maximum 14 Optional Sets the maximum number of archive files of the running configuration to be saved in the configuration archive.

Step 5 time-period minutes Example: Switch config-archive time-period Optional Sets the time increment for automatically saving an archive file of the running configuration in the configuration archive.

Step 7 show running-config Example: Switch show running-config Optional Displays the contents of the running configuration. Performing a Configuration Replacement or Rollback Operation Starting in privileged EXEC mode, follow these steps to replace the running configuration file with a saved configuration file: Command Purpose Step 1 archive config Example: Switch archive config Optional Saves the running configuration file to the configuration archive.

Step 2 configure replace target-url [ list ] [ force ] [ time seconds ] [ nolock ] Example: Switch configure replace flash:startup-config time Replaces the running configuration file with a saved configuration file.
