StackWise, VSS and vPC

• Depending on the switch it will use one of the three versions.  This allows two different switches to support upload links using IP addresses instead of layer two information.
• Commands are very similar to layer 2 except for an additional command in the config-if-range and instead of setting trunk mode in the config-if you set an IP address
  • (config)#int range [interfaces]
  • (config-if-range)#channel-group [group#] mode [active, passive, auto, desirable, on]
  • (config-if-range)#no switchport
  • (config-if-range)#int po[group#]
  • (config-if)#ip address [IPAddress] [Subnet]
  • (config-if)#no shut
