One example of a backbone network is the Internet backbone. Network congestion is often taken into consideration while designing backbones. The pieces of the network connections (for example: Ethernet, wireless) that bring these departments together is often mentioned as network backbone. Ī large corporation that has many locations may have a backbone network that ties all of the locations together, for example, if a server cluster needs to be accessed by different departments of a company that are located at different geographical locations. Normally, the backbone's capacity is greater than the networks connected to it. A backbone can tie together diverse networks in the same building, in different buildings in a campus environment, or over wide areas. IEEE 802.A backbone or core network is a part of a computer network which interconnects networks, providing a path for the exchange of information between different LANs or subnetworks.IEEE 802.1D – Spanning tree compatibility.IEEE 802.1AB – Link Layer Discovery Protocol (LLDP).ARM Cortex-A9 32-bit processor, 400 MHz clock.Note *Based on Max PoE power load for PoE models 1 x 10/100Base-T out-of-band management port.Industry-standard command line interface (CLI) with scripting capabilities.Centralized enterprise management via ExtremeManagement.

And for advanced users, the 220 Series offers an industry-standard CLI along with scripting capabilities.Īll ExtremeSwitching 220 Series switches include a Limited Lifetime Warranty, whichprovides advanced hardware replacement with next business day shipment. The switches can also be set-up via a web browser, or managed by ExtremeManagement for centralized provisioning, monitoring and troubleshooting. The 220 Series also provides multiple management options, including cloud-based management via ExtremeCloud for wired and wireless network oversight through a single pane of glass. In addition to a rich Layer 2 feature set, the 220 Series offers dynamic IPv4 RIP routing services, stacking of up to 4 switches with single IP management, and redundant power supply option. In addition, the 12-port PoE+ and non-PoE+ models can operate in fanless mode, making them ideal for office deployments. All models provide nonblocking Gigabit per port performance and include either 2 or 4 SFP+ ports for highspeed 10Gbps fiber connectivity. The series consists of six switches including 12-, 24-, and 48-port Gigabit Ethernet switches and 12-, 24-, and 48-port Gigabit PoE+ models. The ExtremeSwitching 220 Series is an economical, fixed-configuration family of Gigabit Ethernet Layer 2/3 switches designed for enterprises, branch offices and small to medium-sized businesses looking for key features in a flexible, yet easy-to-manage solution.
