cisco ata device

The ATA trim command is used by the file system to notify devices which logical addresses are no longer occupied and can be recycled as free space by devices. In the ATA command set, the trim command is only the datamanagement set (DMS) the DMs command is specially used for device optimization (the data set management command provides information for deviceoptimi

security considerations provided by Cisco are the use of a local password during Device Access and configuration. Different passwords can be applied to different rows or access pointers. The typical access pointers in Cisco devices are terminal lines (also known as virtual terminal lines, or VTYs), Console ports, and Auxiliary ports (AUX ). In addition, differen

To protect their Cisco networks, many administrators are busy with what traffic can be allowed to pass through network devices, and how to restrict the unique information exchanged between mail route upgrades and other routers. The access control list (ACLs) usually solves these problems quite simply. The security of network devices is important to any networked environment. To solve this problem, Cisco pro

The console port is a port for each network management device. By default, authentication is not performed and plug-and-play is enabled. To ensure security, we can authenticate the console port, there are two authentication methods: 1. password 2. user name + Password Take Cisco configuration as an example: 1. Password Line console 0: Enter the console Port Password

For enterprise users, multi-device port access control can optimize the network more reasonably. Here we analyze in detail how to configure a Cisco router to implement this function. You only need a CISCO router with an asynchronous module or a router with a built-in asynchronous serial port. You can enjoy full control connections to a series of network devices
