Used Cisco Catalyst 6500 Virtual Switching System 1440

Part # VSS1440

Product Description: This VSS network system virtualization technology pools multiple Cisco Catalyst 6500 Series Switches into one virtual switch. It increases operational efficiency and boosts nonstop communications while it scales the system bandwidth capacity to 1.4 Tbps. At the initial phase, a VSS will allow two physical Cisco Catalyst 6500 Series Switches to operate as a single logical virtual switch called a virtual switching system 1440 (VSS1440).

VSS1440 is formed by two Cisco Catalyst 6500 Series Switches with the Virtual Switching Supervisor 720-10GE. The 10 Gigabit Ethernet uplinks on the Virtual Switching Supervisor 720-10G or any port on the WS-X6708-10G module. VSSs supports all Cisco Catalyst 6500 Series Switches 6700 Series modules in centralized or distributed (using DFC3C or DFC3CXL) forwarding mode.

In a VSS, the data plane and switch fabric with capacity of 720 Gbps of supervisor engine in each chassis are active at the same time on both chassis, combining for an active 1400-Gbps switching capacity per VSS. Only one of the virtual switch members has the active control plane. Both chassis are kept in sync with the interchassis Stateful Switchover (SSO) mechanism along with Nonstop Forwarding (NSF) to provide nonstop communication even in the event of failure of one of the member supervisor engines or chassis.
