The core of our network is a double Cisco 6509 in VSS mode. Yestarday, the standby-hot switch
unexpectedly crashed and restarted himself. After that our network has became an unstable work. We saw many collisions in the network. Some switches have not answered for a ping. Then, we decided to turn off the active switch, because
he was the closest thing.
After that second the stanby-hot switch became active and network became to work correctly. Now the one switch is turned off.
Remove the vss links from the problem switching make sure it's isolated from the network and power it up. Once it's on check the config with the active one. We use two 6509s with 2 sups in each (vss) in our core.
