Cisco Catalyst 4500-X Series Switches support Easy Virtual Network (EVN), which simplifies creation of separate logical networks on a single physical infrastructure. Each of these has different security and routing polices, traffic separation, and path isolation. EVN uses existing protocols, along with virtual routing and forwarding (VRF) technology, in a complete network virtualization solution with shared services and enhanced management.
The switches also run the modular IOS XE operating system that supports third-party applications such as Wireshark protocol analyzer. The switches lower capital expenditures (CapEx) while simplifying troubleshooting with Wireshark.
