Conclusion - Cisco Catalyst 6500-E Series Manual

Engine 2T will take over via a subsecond SSO failover. None of the modules in the chassis will go offline, and the
available bandwidth for the VSS will be affected only during the subsecond SSO failover. In the case in which all
DFC4s are used in a chassis and traffic is being locally switched on the module, there might be no traffic effect at
all.

Conclusion

The trends of BYOD, video, and collaboration are forcing IT organizations to rethink how they architect their
infrastructures. The proliferation of wireless devices and speeds in the enterprise is causing a shift in how Cisco
approaches the design of a campus network, moving toward a converged wired/wireless architecture referred to
as a unified access campus architecture. The backbone of the unified access campus architecture is a critical
piece to the design, because it must have the ease of management, application visibility, security, and resilience
to allow delay-sensitive and mission-critical applications to function as expected to meet the business needs of the
user community.
When the requirements of the backbone in the unified access campus architecture are considered, the Cisco
Catalyst 6500-E with Supervisor Engine 2T becomes the outstanding option to support those requirements. When
it comes to the combination of scalability and feature richness, no other platform can match the capabilities of the
Cisco Catalyst 6500-E with Supervisor Engine 2T. Without sacrificing performance, the Cisco Catalyst 6500-E with
Supervisor Engine 2T allows a network administrator to simplify the admin's job through the support of smart
operations while at the same time deploying the security, application visibility/control, and resiliency capabilities
that the newest type of applications demands.
