Spanning-tree mode mst spanning-tree mst configuration name region1 revision 1 spanning-tree mst 0 priority 4096 Set Bridge Priority You can configure the STP bridge priority of any Meraki switch in your network from the STP bridge priority field. By default interfaces on routers are administratively shut down. The spanning tree feature cannot be turned off in switches on a per port basis. As you already it is not recommended to turn STP off. The Spanning Tree Protocol is a network protocol that builds a loop-free logical topology for Ethernet networks. Example of an IOS device compatible configuration.

A common misunderstanding among Cisco students is that portfast disables spanning-tree on a certain interface. Spanning tree uses the extended system ID the device priority and the allocated spanning-tree MAC address to make the bridge ID unique for each VLAN.

A common misunderstanding among Cisco students is that portfast disables spanning-tree on a certain interface. 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. Never disable Spanning Tree Protocol STP if there is no valid reason to disable it. The Spanning Tree Protocol is a network protocol that builds a loop-free logical topology for Ethernet networks.

Also ensure that all switches and bridges in the VLAN have spanning tree disabled. This is not correct howeverif you enable portfast on an interface then it will jump to the forwarding state of spanning-tree. Is there a way to turn off the Spanning-Tree protocol. 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. 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. As Aref mentioned you can disable globally the STP instance for a VLAN with the no spanning-tree vlan x command. 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.
