Note This command will not be visible on the device after the configuration, but will continue to function. Figure 1-6 Virtual Switch at the Distribution layer Loop Free Topology VLAN = Subnet. This is shown in the configuration, even if it the default. Unfortunately it’s going to reboot one switch at a time, and when that switch goes down, it’s not going. Further, VSS, has IAs on 6xxxx platforms (I recall the technology is being dropped), and VPC offers fabric extensions devices. StackWise; Virtual Switching System (VSS) StackWise¶ StackWise and StackWise Plus options available; Supported on Catalyst 3750-E, 3750-X and 3850; Uses special “stacking” cables deployed in a daisy-chain to form a ring; Traffic is carried bi-directional across the stacking switch fabric;The big functional difference, VSS behaves as one logical device (although it avoids moving traffic ti/from its peer) while VPC operates as two logical devices except for the VPC port-channel. Cisco's documentation is not very clear on this. Execute the conversion command, which will reboot the switches. Another point in favor of stacking is the optics required back to distribution. Switches in a Cisco StackWise Virtual solution increase operational efficiency by using single control and management plane, scale system bandwidth with distributed forwarding plane, and assist in building resilient networks.
