The chassis supports 240 10 Gigabit Ethernet ports and is future-ready to support 40 Gigabit Ethernet and 100 Gigabit Ethernet interfaces. The system also supports Shortest Path Bridging, for network-wide service abstraction and orchestration (which may involve tens or hundreds of nodes), and Switch Clustering which delivers multi-device virtualization and high availability (typically deployed as pairs). This product can also maintain over 4000 VLANs and IP interfaces with support for up to 10k Static IP Routes, and an IP Forwarding Table capacity for 500k entries. Some more technological performance measures stack up as follows:
