High Performance Switching and Routing
Summit X480 is available in three different port configuration options: 24-port Gigabit Ethernet and 2-port 10 Gigabit Ethernet ( Summit X480-24x) , 48-port copper Gigabit Ethernet ( Summit X480-48t) , or 48-port fiber Gigabit Ethernet ( Summit X480-48x) . All ports run at non-blocking, wire-speed performance. Flexible configuration offered by using optional VIM2 modules which are: 4-port 10 Gigabit Ethernet Module ( VIM2-10G4X) , 2-port SummitStack Module ( VIM2-SummitStack) and 2-port SummitStack128 Module ( VIM2-SummitStack128) .

High Scalability in 1RU Compact Switch
Summit X480 supports highly scalable Layer 2 or Layer 3 networks, as well as highly secure networks. For larger Layer 2 network deployments, Summit X480 can support up to 512K MAC addresses. Similarly for larger Layer 3 routing environments, Summit X480 can support core routing class scalability for up to 512K IPv4 routing LPM entries in hardware.

Intelligent Switching and MPLS support
Summit X480 supports intelligent Layer 2 switching, as well as Layer 3 IPv4/ IPv6 routing at a very high scale. For Carrier Ethernet network deployment, Summit X480 supports MPLS LSP based Layer 3 forwarding and Hierarchical VPLS ( H-VPLS) for transparent LAN services. With H-VPLS, transparent Layer 3 networks can be extended throughout the Layer 3 network cloud by using a VPLS tunnel between the regional transparent LAN services typically built by Provider Bridging ( IEEE 802.1ad) technology.
