   • When VSL is configured, all existing configurations are removed from the interface except for specific commands. When configuring VSL, the system puts the interface into a restricted mode. This means that only specific configuration commands can be configured on the interface.
   • The following VSL configuration commands are inserted automatically on all VSL member ports: • switchport mode trunk • switchport nonegotiate • no lldp transmit • no lldp receive • no cdp enable • service-policy output VSL-Queuing-Policy
   • In VSL restricted mode, only these configuration commands are available: • channel-group • default • description • exit • load-interval • logging • no • power • shutdown

   • An access switch connects to both switches of the VSS using one logical port channel. The VSS manages redundancy and load balancing on the port channel. This capability enables a loop-free Layer 2 network topology. The VSS also simplifies the Layer 3 network topology by reducing the number of routing peers in the network.
