avayaspanning treeswitch

I know how to connect a switch on a router Avaya VSP 7200 by disabling STP with the command :

no spanning-tree mstp force-port-state enable

but how to force port state on a switch Avaya 4950?

Thank you for helping

I don't know about the 4900, but on the 5000 (5xxx) line I use the following:

interface FastEthernet ALL
spanning-tree rstp port 21-22 learning disable
exit

(21 is a cablemodem, 22 is the router)

STP will show the ports as Discarding, but they aren't:

troz-5510-1#show spanning-tree rstp port role 21-22
Port     Role       State     STP Status  Oper Status
----  ----------  ----------  ----------  -----------
21    Disabled    Discarding  Disabled    Disabled     
22    Disabled    Discarding  Disabled    Disabled 

troz-5510-1#show interfaces 21-22 
              Status                    Auto                       Flow
