Multilayer Switching: A 10Gb switch generally supports Layer 2 or Layer 3 switching, combining the flexibility of Layer 2 with the stability and high performance of Layer 3. VLAN Support: Supports up to 4K VLANs, as well as various VLAN functions such as Guest VLAN and Voice VLAN. It expanded Ethernet speeds tenfold beyond 1 GbE while preserving Ethernet's familiar MAC layer and frame structure. The standard defines both Media Access Control (MAC) enhancements and multiple Physical Layer (PHY) options to ensure performance and interoperability across different network. 10 Gigabit Ethernet (10GE, 10GbE, or 10 GigE) is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. It was first defined by the IEEE 802. Unlike previous Ethernet standards, 10GbE defines only full-duplex. The switches maintain all the existing Cisco Nexus 5500 platform features, including LAN and SAN convergence (unified ports and Fibre Channel over Ethernet ), fabric extenders, and Cisco ® FabricPath. 3ae that enables data transmission at a rate of 10 billion bits per second. The physical layer subgroups are: 10GBASE-R: Developed for optical fiber medium. 10GBASE-T: Developed for. Under the International Standards Organization's Open Systems Interconnection (OSI) model, Ethernet is fundamentally a Layer 2 protocol.
