Core Product Positioning
The Cisco WS-X6K-SUP2T-10G Supervisor Engine 2T is the highest-performance generation supervisor module built exclusively for Catalyst 6500 E-Series chassis. It integrates a 2 Tbps non-blocking crossbar switching fabric delivering 80 Gbps dedicated full-duplex bandwidth per slot. Powered by PFC4 Policy Feature Card and MSFC5 multilayer route processor, it supports hardware acceleration for L2/L3, IPv4/IPv6, MPLS, Cisco TrustSec and VSS (Virtual Switching System). Designed for large enterprise campus core, high-density data center aggregation, service provider metro Ethernet and IP/MPLS edge deployments. It offers broad backward compatibility with legacy Catalyst 6500 line cards while enabling next-generation feature sets to maximize investment protection.
