Turn Off Spanning Tree Cisco. The Spanning Tree Protocol is a network protocol that builds a loop-free logical topology for Ethernet networks. There is no global command to disable spanning tree globally. For example if a stack member is powered off and at the same time the link connecting the stack root to the spanning-tree root comes back up the normal spanning-tree convergence occurs. Also ensure that all switches and bridges in the VLAN have spanning tree disabled.

The spanning tree feature cannot be turned off in switches on a per port basis. Use the no spanning-tree vlan vlan-id. The station_update_rate value in the UplinkFast command represents the number of dummy multicast packets that are transmitted per 100 ms the default is 15 packets per 100 ms in the event of a direct link failure.

Also the root bridge is the one that traffic always flows over between branches. Use the no spanning-tree vlan vlan-id command in order to disable STP on a per virtual LAN VLAN basis. With this operating system PAgP is not active until you add a port to an EtherChannel so you do not need to turn PAgP off. Although it is not recommended you can turn off Spanning Tree Protocol STP on a per-VLAN basis or globally on the switch. SW1sh span Mar 1 221800536.

Here are some steps to disable it at the port level. All of our hotels use Procurve switches at the edge 2910al-PoE or 2520-8G-PoE all participate in spanning tree but we only observe the flapping on about 1 of switchports. Also the root bridge is the one that traffic always flows over between branches. For example if a stack member is powered off and at the same time the link connecting the stack root to the spanning-tree root comes back up the normal spanning-tree convergence occurs. You can issue the interface range command in order to apply these commands to a group of ports at one time.
