Configuring Spanning Tree Edge Ports on Specified Interfaces

You can configure spanning tree edge ports on specified interfaces. Interfaces configured as spanning tree
edge ports immediately transition to the forwarding state, without passing through the blocking or learning
states, on linkup.
This command has four states:
• spanning-tree port type edge—This command explicitly enables edge behavior on the access port.
• spanning-tree port type edge trunk—This command explicitly enables edge behavior on the trunk

Purpose
Enters configuration mode.
Configures all interfaces as edge ports. This assumes all ports are connected to
hosts/servers. Edge ports immediately transition to the forwarding state without
passing through the blocking or learning state at linkup. By default, spanning
tree ports are normal port types.
Configures all interfaces as spanning tree network ports. This assumes all ports
are connected to switches and bridges. If you enable Bridge Assurance, it
automatically runs on network ports. By default, spanning tree ports are normal
port types.
Note
port.
If you configure interfaces connected to hosts as network ports, those
ports automatically move into the blocking state.
