This allows a technician sitting in a Network Operations Center thousands of miles away the ability to restore a switch or perform an initialization configuration securely over a standard telephone line even if the primary network is in failure. This creates a secondary path to the switch outside the bandwidth of the network which needs to be secured without relying on the primary network.
By connecting to the console port you can get remote access to the root level of a switch without using the network that the switch is connected to. A complete remote management system allows remote reboot, shut-down, powering on hardware sensor monitoring (fan speed, power voltages, chassis intrusion, etc.) Out band Management ports is also called as Ethernet Management port (RJ45).Ĭonsole:Switch console ports are meant to allow root access to the switch via a dumb terminal interface, regardless of the state of the switch (unless it is completely dead). It also can be used to ensure management connectivity (including the ability to determine the status of any network component) independent of the status of other in-band network components. This allows the network operator to establish trust boundaries in accessing the management function to apply it to network resources. Fiber optics has several advantages over traditional metal communications lines: Fiber optic cables have a much greater bandwidth than metal cables.Įthernet Port: out-of-band management involves the use of a dedicated channel for managing network devices. Fiber cable:A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves.
