AV Line of Fully Managed Switches M4250 Series Main User Manual • Software: The system software image, which is saved in one of two flash sectors called images (image1 and image2). 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 corrupted, the system automatically boots from the nonactive image. This is a safety feature for faults occurring during the boot upgrade process. This is the default setting. • Text Configuration: A text-based configuration file enables you to edit a configured text file (startup-config) offline as needed. 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 (for example, change the device name or IP address), and download it to that device. • SSH-2 RSA Key PEM File: An SSH-2 Rivest-Shamir-Adelman (RSA) key file (PEM Encoded). • SSH-2 DSA Key PEM File: An SSH-2 Digital Signature Algorithm (DSA) key file (PEM Encoded). • SSL Trusted Root Certificate PEM File: An SSL Trusted Root Certificate file (PEM Encoded). • SSL Server Certificate PEM File: An SSL Server Certificate file (PEM Encoded) to the device. • SSL DH 1024 Encryption Parameter PEM File: An SSL Diffie-Hellman 1048-bit Encryption Parameter File (PEM Encoded) to the device. • SSL DH 2048 Encryption Parameter PEM File: An SSL Diffie-Hellman 2048-bit Encryption Parameter File (PEM Encoded) to the device. • Config Script: A text-based configuration script file. You must use the command-line interface (CLI) to configure, validate, and activate the script. • CLI Banner: The CLI banner contains the text to be displayed on the CLI before the login prompt. • IAS Users: The Internal Authentication Server (IAS) users database file. The IAS user database stores a list of user name and (optional) password values for local port-based user authentication. • Factory Default Configuration: The factory default configuration file is a text-based file with the stored factory default configuration. • Public Key Configuration: The public key file used for configuration script validation. • DHCP Client Configuration File: The DHCP client configuration file with the DHCP server (host) information. 6.
