Ethernet Switches

With the industry’s most advanced offering of highly integrated, low-power switches, Vitesse continues to set the pace of innovation.

Switching
• Nonblocking, wire-speed, hardware-based and CPU-based learning that are configurable per port
• Jumbo frame support
• Multiple Spanning Tree protocol support (IEEE Std 802.1w, IEEE Std 802.1s, or IEEE Std 802.1D)
• Programmable link aggregation traffic distribution (IEEE 802.3ad)

Integration
• Integrated processors, memory subsystems, dual-media GbE PHYs, and numerous features; provides low power, reduced BOM costs, minimum board space, and superior performance
• Software integration using either turn-key Vitesse software or software development kit

Management
• Integrated CPU supports managed solutions and is also configurable to support an external CPU
• Vitesse VeriPHY® cable diagnostics technology (for devices with integrated transceivers)
• Web–based or console–based software stack available from Vitesse (except VSC7384)

QoS
• Programmable multilayer classifier with four QoS classes per port
• QoS classification based on IEEE 802.1p, EtherType, VID, IPv4/IPv6 DSCP, and UDP/TCP ports/ranges
• Broadcast and multicast storm control, as well as flooding control
• Full-duplex flow control (IEEE 802.3x) and half-duplex backpressure

Stacking (VSC7407)
• Hardware-based learning and synchronization of MAC table across stack
• Hardware-based loop prevention using shortest path forwarding and support for fast fail-over
• Link aggregation across stack

Security
• Port-based access control (IEEE 802.1X)
• Snooping for an extensive array of frame types
• CPU mirroring per port and per VLAN
• Advanced ACL support through TCAM-based match patterns (VSC7401, VSC7405, and VSC7407)
