End of sale refers to the time when certain products are no longer available for new purchases. It does not apply to the service and support

programs for those products. Cisco will continue to support these products after End of Sale through the SMARTnet™ and Comprehensive

Maintenance programs. Customers with either of these service contracts are entitled to free software updates, 24-hour phone support through

the Cisco Technical Assistance Center (TAC), and advance replaced hardware for repairs. Comprehensive Maintenance customers also

receive onsite service. Customers who do not have a maintenance contract can purchase software updates and hardware repair services from

Cisco to meet specific requirements rather than full-service coverage. Cisco is committed to providing software support for three years and

providing hardware support for a period of five years after the End of Sale date.
