Environment variables that have values are stored in flash memory outside of the flash file system. Each line in these files contains an environment variable name and an equal sign followed by the value of the variable.
A variable has no value if it is not present; it has a value if it is listed even if the value is a null string. Many environment variables are predefined and have default values. You can change the settings of the environment variables by accessing the boot loader or by using Cisco IOS commands.
Under normal circumstances, it is not necessary to alter the setting of the environment variables. This table describes the function of the most common environment variables. A semicolon-separated list of executable files to try to load and execute when automatically booting. Specifies the Cisco IOS image to load during the next boot cycle.
This command changes the setting of the BOOT environment variable. When booting in installed mode, the package provisioning file specified in the boot command is used to determine which packages to activate.
For example boot flash:packages. When booting in bundle mode, the package provisioning file contained in the booted bundle is used to activate the packages included in the bundle.
For example, boot flash:image. Valid values are 1, yes, 0, and no. If it is set to no or 0, the boot loader attempts to automatically boot up the system.
If it is set to anything else, you must manually boot up the switch from the boot loader mode. The next time you reboot the system, the switch is in boot loader mode. Changes the filename that Cisco IOS uses to read and write a nonvolatile copy of the system configuration. Specifies the filename that Cisco IOS uses to read and write a nonvolatile copy of the system configuration. Enables a break to the auto-boot cycle. You have 5 seconds to enter the break command.
When the switch is connected to a PC through the Ethernet management port, you can download or upload a configuration file to the boot loader by using TFTP. Make sure the environment variables in this table are configured.
However, if you modify this variable after the boot loader is up or the value is different from the saved value, enter this command before using TFTP. A reset is required for the new value to take effect. Specifies the IP address and the subnet mask for the associated IP subnet of the switch. You can schedule a reload of the software image to occur on the device at a later time for example, late at night or during the weekend when the device is used less , or you can synchronize a reload network-wide for example, to perform a software upgrade on all device in the network.
Reload of the software to take affect in the specified minutes or hours and minutes. The reload must take place within approximately 24 hours. You can specify the reason for the reload in a string up to characters in length. Reload of the software to take place at the specified time using a hour clock. If you specify the month and day, the reload is scheduled to take place at the specified time and date.
If you do not specify the month and day, the reload takes place at the specified time on the current day if the specified time is later than the current time or on the next day if the specified time is earlier than the current time. Specifying schedules the reload for midnight. The reload command halts the system. If the system is not set to manually boot up, it reboots itself. If your device is configured for manual booting, do not reload it from a virtual terminal.
If you modify your configuration file, the device prompts you to save the configuration before reloading. If you proceed in this situation, the system enters setup mode upon reload. To cancel a previously scheduled reload, use the reload cancel privileged EXEC command. Using DHCP to download a new image and a new configuration to a device requires that you configure at least two devices. One device acts as a DHCP and TFTP server and the second device client is configured to download either a new configuration file or a new configuration file and a new image file.
The prefix length specifies the number of bits that comprise the address prefix. The prefix is an alternative way of specifying the network mask of the client. You should only configure and enable the Layer 3 interface. This task describes how to manually assign IP information to multiple switched virtual interfaces SVIs :. The range is 1 to Enters the IP address of the next-hop router interface that is directly connected to the device where a default gateway is being configured. The default gateway receives IP packets with unresolved destination IP addresses from the device.
Once the default gateway is configured, the device has connectivity to the remote networks with which a host needs to communicate. When your device is configured to route with IP, it does not need to have a default gateway set. The device capwap relays on default-gateway configuration to support routed access point join the device. The following sections provide information on how to modify the startup configuration of a device.
By default, the Cisco IOS software uses the config. However, you can specify a different filename, which will be loaded during the next boot cycle. By default, the switch automatically boots up; however, you can configure it to manually boot up.
The next time you reboot the system, the switch is in boot loader mode, shown by the switch: prompt. For file-url —Specifies the path directory and the name of the bootable image. This command extracts the individual components of the. The auto-abort-timer keyword, automatically rolls back the software image activation. The automatic timer is triggered after the new image is activated.
If the timer expires prior to the issuing of the install commit command, then the install process is automatically terminated. The device reloads, and boots up with a previous version of the software image. Optional Terminates the software install activation, and rolls back to the version that was running before current installation procedure.
You can use this command only when the image is in an activated state; and not when the image is in a committed state. The install commit command completes the new image installation. Changes are persistent across reloads until the auto-abort timer expires.
The output of this command varies according to the install commands that are configured. The following procedure explains how to boot the device from the TFTP server in the bundle mode.
This task describes how to configure your device to reload the software image at a later time. Saves your device configuration information to the startup configuration before you use the reload command. Schedules a reload of the software to take affect in the specified minutes or hours and minutes.
The reload must take place within approximately 24 days. Use the at keyword only if the device system clock has been set through Network Time Protocol NTP , the hardware calendar, or manually.
The time is relative to the configured time zone on the device. To schedule reloads across several devices to occur simultaneously, the time on each device must be synchronized with NTP.
Displays information about a previously scheduled reload or identifies if a reload has been scheduled on the device.
The following is a sample output of the emergency-install boot command:. The following is a sample output from the install remove inactive command:. The following is sample output from the install abort command:. The following is a sample output from the install activate auto-abort-timer command:.
Displays information about all the software install operations that was performed since boot-up of the device.
The output of this command differs based on the install command that is executed. This example shows how to reload the software on a device on the current day at p. Command Reference Catalyst Series Switches. This table provides release and related information for features explained in this module. These features are available on all releases subsequent to the one they were introduced in, unless noted otherwise.

The normal boot process involves the operation of the boot loader software and includes these activities: Performs low-level CPU initialization.
Initializes the file systems on the system board. Loads a default operating system software image into memory and boots up the device.
As part of POST, the following test s are also performed: Power over Ethernet PoE controller functionality test to check the chip accessibility, firmware download, and health status of the power-sourcing equipment.
Thermal test to verify the temperature reading from the device sensor. Before you can assign device information, make sure you have connected a PC or terminal to the console port or a PC to the Ethernet management port, and make sure you have configured the PC or terminal-emulation software baud rate and character format to match these of the device console port: Baud rate default is During a session conflict or client misuse of the global lock, NETCONF sessions can be monitored via the show netconf-yang sessions command, and non-responsive sessions can be cleared using the clear configuration lock command.
External facing interfaces will provide dual-stack support; both IPv4 and IPv6. Revision statements embedded in the YANG files indicate if there has been a model revision. All operational data models provide direct operational data model access, hence this feature is no longer required. Secures critical configuration, keys, and passwords by encrypting them. An instance-unique encryption key is stored in the hardware trust anchor to prevent it from being compromised.
This feature is enabled on platforms that come with a hardware trust anchor, by default and is not supported on platforms that do not have a hardware trust anchor. Removes all customer specific data that has been added to the device since the time of its shipping. Data erased includes configurations, logfiles, bootvariables, corefiles, and credentials. Enables configuration of the maximum segment size for transient packets that traverse the device during a TCP session. Also referred to as reflective relay, the feature moves switching out of the server, back to the physical network, and makes all virtual machine traffic visible to the external network switch.
This frees up server resources to support virtual machines. VEPA provides several benefits to Virtual Ethernet Bridge VEB , which is a physical end station capability that supports local bridging between multiple virtual end stations. You can try sample Python scripts to see how the network device responds to them and get a better understanding of how Python APIs operate on the device. You can safely run your Python scripts in the sandbox before applying them to the network device.
Expose the password life time details from AAA to Web UI—A new security mechanism for defining rules, constraints and restrictions when specifying user passwords. This means that entering enter a question mark? Such hidden commands are only meant to assist Cisco TAC in advanced troubleshooting and are therefore not documented. Begin by entering the service internal command to access these commands.
Category 2—Hidden commands in one of the configuration modes global, interface and so on. These commands do not require the service internal command. The commands have CLI help. Entering enter a question mark? Note: For Category 1, enter the service internal command before you enter the question mark; you do not have to do this for Category 2.
We recommend that you use any hidden command only under TAC supervision. If you find that you are using a hidden command, open a TAC case for help with finding another way of collecting the same information as the hidden command for a hidden EXEC mode command , or to configure the same functionality for a hidden configuration mode command using non-hidden commands.
The following table lists the supported hardware models and the default license levels they are delivered with. For information about the available license levels, see section License Levels. Stackable 48 36 2. The following table lists the optional uplink network modules with 1-Gigabit, Gigabit, Gigabit, and Gigabit slots. You should only operate the switch with either a network module or a blank module installed.
CNM-4G 1. CNM-4M 1. CNM-8X 1. CNM-2Q 1. CNM-2Y 1. Cisco Catalyst Series Switches support a wide range of optics and the list of supported optics is updated on a regular basis. See Cisco Prime Infrastructure 3. The following subsections list the hardware and software required to access the Web UI:. This section covers the various aspects of upgrading or downgrading the device software.
You can use the show version privileged EXEC command to see the software version that is running on your switch. You can also use the dir filesystem: privileged EXEC command to see the directory names of other software images that you might have stored in flash memory.
When you upgrade from the existing release on your switch to a later or newer release for the first time, the boot loader may be automatically upgraded, based on the hardware version of the switch. If the boot loader is automatically upgraded, it will take effect on the next reload. If you go back to the older release after this, the boot loader is not downgraded.
The updated boot loader supports all previous releases. Do not restart the switch during the upgrade or downgrade process. It takes approximately an additional 4 minutes to complete the microcode upgrade in addition to the normal reload time; however, data traffic continues to be forwarded during the upgrade.
It does not occur during switch reloads or on non-PoE switches. To install and activate the specified file, and to commit changes to be persistent across reloads:. To separately install, activate, commit, cancel, or remove the installation file: install?
Copies the install file package from a remote location to the device and performs a compatibility check for the platform and image versions. Activates the file, and reloads the device. The auto-abort-timer keyword automatically rolls back image activation. Cancels file activation, and rolls back to the version that was running before the current installation procedure started. Summary of request platform software Commands.
Only request platform software commands. Either install commands or request platform software commands. Ensure that you have at least 1GB of space in flash to expand a new image. Clean up old installation files in case of insufficient space. The following sample output displays the cleaning up of unused files, by using the request platform software package clean command for upgrade scenario Cisco IOS XE Everest Use the switch all option to clean up all the switches in your stack.
Use this command to set the boot variable to flash:packages. Use this command to verify the boot variable is set to flash:packages. You can point to the source image on your TFTP server or in flash if you have it copied 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 the software has been successfully installed, use this command to verify that the flash partition has ten new.
