| | Key Technical Considerations | | :--- | :--- | | Catalyst 4500-E Series Switches | Supports Supervisor Engines 9-E, 8L-E, 8-E, 7L-E, and 7-E . | | VSS (Virtual Switching System) Deployments | Used in VSS environments, where two physical switches combine into one virtual unit for high availability and management simplification. | | Gold Star Designation | Considered a "Gold Star" recommendation on Cisco's software portal for the C4500X-32 platform, indicating it has passed rigorous testing. | The "E" family signifies an Extended Maintenance release
For older Supervisor Engines, this version provides a modern feature set without overutilizing onboard DRAM or Flash memory.
: Unlocks advanced dynamic routing protocols including full OSPF, BGP, Intermediate System-to-Intermediate System (IS-IS), advanced Multicast (PIM, IGMP), and Multiprotocol Label Switching (MPLS). High Availability and Resiliency Features
: The standard file extension for a binary executable file that the switch loads into RAM during the boot sequence. Target Hardware and Supervisor Engine Compatibility
