LACP and RSTP

Hi,

i have a stupid question

i have a 3750 in the stack and other 3750 stack (connect over wan, there are not possible connect over LACP or FlexLink) and extreme switch connect over LACP

But i don't now how must be configuration STP on the LACP link between server and extreme switch.

I have loop only between two 3750 stack.

LACP for servers (not trunk)

- there are must be spanning tree portfast or not? (on picture number 3.)

what the correct settings i think that is possible shutdown LACP fort these ports, because LACP is single cable.

interface Port-channel11

switchport access vlan 10

spanning-tree portfast

interface GigabitEthernet1/0/23

spanning-tree portfast

channel-group 11 mode active

interface GigabitEthernet2/0/23

description ***LAN***

switchport access vlan 10

spanning-tree portfast

channel-group 11 mode active

is it possible shutdown STP fort these ports? or what the correct settings for ports connect over LACP to the SERVER.

LACP with TRUNK between extreme switch (on picture  number 1. and 2.)

- what the correct settings i think that is possible shutdown LACP fort these ports, because LACP is single cable.

- here must be STP, because other switch is over wan
