I have seen topologies with vss (labelled) switches using IOU but I can't seem to find any that support it. I've only tried 3 images so far. I have 2 6513 switches configured in a vss configuration and I want to try and replicate the environment as best I can in GNS3. So yeah if anyone knows please let me know :)
Virtual Switching System (VSS) is a method to combine two physical switches into one logical switch to achieve physical redundancy, Spanning-Tree blocking elimination, and increased bandwidth. VSS was first available in Cisco 6500 but it has recently been introduced to Cisco 4500 and 4500X. This article provides configuration that will allow you to easily enable VSS on these switches.
