Using System Utilities

The System Utilities feature menu contains links to Web pages that help you configure features that help you manage the switch.

Save All Applied Changes

When you click Submit, the changes are applied to the system and saved in the running configuration file. However, these changes are not saved to non-volatile memory and will be lost if the system resets. Use the Save All Applied Changes page to make the changes you submit persist across a system reset.

To access the Save All Applied Changes page, click System > System Utilities > Save All Applied Changes in the navigation menu.

save_changes

Click Save to save all changes applied to the system to NVRAM so that they are retained if the system reboots.

System Reset

Use the System Reset page to reboot the system. If the platform supports stacking, you can reset any of the switches in the stack, or all switches in the stack from this page.

To access the System Reset page, click System > System Utilities > System Reset in the navigation menu.

system_reset

For Stacking platforms, you can select one or all switches in the stack to reset from the drop-down menu. For platforms that do not support stacking, this field is not present. Click Reset to initiate the system reset. If you have not saved the changes that you submitted since the last system reset, the changes will not be applied to the system after the reset.

Reset Configuration to Defaults

Use the Reset Configuration to Defaults page to reset the system configuration to the factory default values.

NOTE: By default, the switch does not have an IP address, and the DHCP client is disabled. When you reset the system to its default values, you will not be able to access the Web interface until you connect to the CLI through the serial port and configure network information.

To access the Reset Configuration to Defaults page, click System > System Utilities > Reset Configuration to Defaults in the navigation menu.

Download File To Switch (TFTP)

Use the Download File to Switch page to download device software, the image file, the configuration files, and SSH or SSL files from a TFTP server to the switch. You can also download files through HTTP.

To access the Download File to Switch page, click System > System Utilities > Download File to Switch in the navigation menu.

download_file

Download File to Switch Fields

Field	Description
File Type	Specify what type of file you want to download to the switch: Code: The code is the system software image, which is saved in one of two designated files in the file system called images (active and backup). The active image stores the active copy; while the other image stores a second copy. The device boots and runs from the active image. If the active image is corrupt, the system automatically boots from the non-active image. This is a safety feature for faults occurring during the boot upgrade process. Configuration: If you have a copy of a valid TejNOS-EN configuration file (TejNOS-EN.cfg) on a TFTP server, you can download it to the switch to overwrite the running and startup configuration files. Upon a successful file transfer, the settings in the configuration file you upload are applied to the switch, and the configuration persists across a system reset. If the file has errors, the update is stopped. The configuration file is not a text file and cannot be edited by using a text editor. Text Configuration: A text-based configuration file enables you to edit a configured text file (startup-config) offline as needed without having to translate the contents for TejNOS-EN to understand. The most common usage of text-based configuration is to upload a working configuration from a device, edit it offline to personalize it for another similar device, and download it to that device. SSH-1 RSA Key File: SSH-1 Rivest-Shamir-Adleman (RSA) Key File. To download SSH key files, SSH must be administratively disabled and there can be no active SSH sessions. SSH-2 RSA Key PEM File: SSH-2 Rivest-Shamir-Adleman (RSA) Key File (PEM Encoded). To download SSH key files, SSH must be administratively disabled and there can be no active SSH sessions. SSH-2 DSA Key PEM File: SSH-2 Digital Signature Algorithm (DSA) Key File (PEM Encoded). To download SSH key files, SSH must be administratively disabled and there can be no active SSH sessions. SSL Trusted Root Certificate PEM File: SSL Trusted Root Certificate File (PEM Encoded). SSL Server Certificate PEM File: SSL Server Certificate File (PEM Encoded). SSL DH Weak Encryption Parameter PEM File: SSL Diffie-Hellman Weak Encryption Parameter File (PEM Encoded).

Dual Image Configuration

The system maintains two versions of the TejNOS-EN software in permanent storage. One image is the active image, and the second image is the backup image. The active image is loaded during subsequent switch restarts. This feature reduces switch down time when upgrading/downgrading the TejNOS-EN software. The system running an older software version will ignore (not load) a configuration file created by the newer software version. When a configuration file created by the newer software version is discovered by the system running an older version of the software, the system will display an appropriate warning to the user.

Use the Dual Image Configuration page to set the boot image.

AutoInstall

The AutoInstall feature enables the configuration of a switch automatically when the device is turned on and, during the boot process, no configuration file is found in device storage. By communicating with a DHCP server, AutoInstall obtains an IP address for the switch and an IP address for a TFTP server. AutoInstall attempts to download a configuration file from the TFTP server and install in on the switch.

The DHCP server that the switch communicates with must provide the following information:

The IP address and subnet mask (option 1) to be assigned to the switch.
The IP address of a default gateway (option 3), if needed for IP communication.
The identification of the TFTP server from which to obtain the boot file. This is given by any of the following fields, in the priority shown (highest to lowest):
- The sname field of the DHCP reply.
- The hostname of the TFTP server (option 66). Either the TFTP address or name is specified—not both—in most network configurations. If a TFTP hostname is given, a DNS server is required to translate the name to an IP address.
- The IP address of the TFTP server (option 150).
- The address of the TFTP server supplied in the siaddr field.
- The name of the configuration file (boot file or option 67) to be downloaded from the TFTP server. The boot file name must have a file type of *.cfg.
The IP addresses of DNS name servers (option 6). The IP addresses of DNS name servers should be returned from the DHCP server only if the DNS server is in the same LAN as the switch performing AutoInstall. A DNS server is needed to resolve the IP address of the TFTP server if only the “sname” or option 66 values are returned to the switch.

After obtaining IP addresses for both the switch and the TFTP server, the AutoInstall feature attempts to download a host-specific configuration file using the boot file name specified by the DHCP server. If the switch fails to obtain the file, it will retry indefinitely.

To display the AutoInstall page, click System > System Utilities> AutoInstall.

autoinstall

AutoInstall

Field	Description
AutoInstall Mode	Select Start to initiate sending a request to a DHCP server to obtain an IP address of a server and the configuration file name. If it obtains the server address, AutoInstall proceeds to search for and download a configuration file from the server. If successful, it applies the configuration file to the switch. After starting the AutoInstall process, you can monitor the status of the process by the messages in the AutoInstall State and Retry Count fields. You can click Stop to end the process.
AutoSave Mode	Enable or disable saving the network configuration to non-volatile memory. When enabled, the configuration is saved after downloading from the TFTP server without operator intervention. When disabled, the operator must explicitly save the configuration, if needed.
Retry Count	The number of times the switch has attempted to contact the TFTP server during the current AutoInstall session.
AutoInstall State	The status of the current or most recently completed AutoInstall session.

Click Refresh to display the most recently configured AutoInstall state from the switch.
