Innovation for Cisco Catalyst 6500 Series Switches

The world's leading network infrastructure software, Cisco IOS Software, delivers transparent integration of technology innovations, business-critical services, and valuable hardware support.

Cisco IOS® Software Release 15.1(1)SY is the first converged software release for Cisco Catalyst 6500 Series Switches that supports both Supervisor Engine 2T (Sup2T) and Supervisor Engine 720 (Sup720-3B and Sup720-10G).

Features and Capabilities

Release 15.1SY adds more than 175 new features for Catalyst 6500 Switches:

  • Cisco TrustSecâ„¢ security enhancements to improve end-to-end deployments, including Security Group Tag (SGT) caching to facilitate secure transport across deep packet inspection services and Monitor Mode to enable simulation and testing of access control policies before deployment.
  • More granular application visibility and control features, including IPv6 bridged flows, IP aware MPLS NetFlow in hardware on Sup2T, medianet metadata, and hierarchical shaping and queuing, which together improve performance, user experience, and monitoring.
  • Resiliency improvements to optimize business continuity, including several non-stop forwarding, stateful switchover, and graceful restart features.
  • Cisco Catalyst SmartOperations features to lower operating costs, including the ability of the Catalyst 6500 to serve as a Smart Install Director, dramatically simplify the deployment of downstream switches by controlling Cisco IOS Software images and configurations.
