 ## Global Parameters
 
 * **stp.protocol** (one of stp, mstp, rstp or pvrst) -- Global STP flavor to run on supporting nodes, default **stp**
-* **stp.host_edge_port** (bool) -- Configure ports with only hosts connected as 'edge' port_type on platforms that support it, default **True**
+* **stp.stub_port_type** (one of 'normal','edge','network','auto' or 'none') -- Port type to configure on ports with only hosts connected, default **'edge'**

 ## Node Parameters (global or per VLAN)
 
 * **stp.priority** (int 0..61440 in increments of 1024) -- STP priority for root election, by default, all nodes have equal priority 32656.  In case of equal priority, the bridge with the lowest MAC address becomes root; note that MAC addresses are assigned randomly in Netlab
-* **stp.port_type** (one of 'normal','edge','network') -- STP port type for all interfaces connected to this link
+* **stp.port_type** (one of 'normal','edge','network' or 'auto') -- STP port type for all interfaces connected to this link
 
 ## Interface Parameters
 
 * **stp.port_priority** (int 0..15) -- STP port priority for selecting between multiple ports; ports are blocked based on priority (lower value = higher priority). The priority is sent over the wire (4 bits) as the most significant part of the port ID; it is used by the node *receiving* it (!) to decide which port(s) to unblock. Note that on many platforms, the value that ends up in the configuration is a multiple (x16) of this attribute
-* **stp.port_type** (one of 'normal','edge','network') -- STP port type for this interface, default 'normal'
+* **stp.port_type** (one of 'normal','edge','network' or 'auto') -- STP port type for this interface, default 'normal'
