Usage STP is a standard inter-switch protocol used to ensure that an ad hoc network topology is loop-free at Layer 2, on a per VLAN basis. If your network connections form loops, and STP is disabled, packets recirculate between the switches, and cause a decrease in network performance. If you are certain that your network is loop-free, you do not need to enable STP. Use this command to enable or disable STP on the network.
Examples To enable STP, use the following command:
CLI (network-admin@switch) > stp-modify enable
