[c-nsp] Port channel problem

[Kurkdjian, Christian Andres]

 Hi, 
	I am trying to configure a L2 etherchannel (2Gb) between an 7609 (s72033-psv-mz.122-18.SXD6.bin) and a WS-C3560G-24TS (12.2(25)SED1) but I have a problem:
The 3750 GE ports appears me like "suspended". I don´t know the reason, anyone knows why it happens?

These are the configurations:

7609:

interface GigabitEthernet1/19
 no ip address
 speed nonegotiate
 flowcontrol send off
 switchport
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 100
 switchport mode trunk
 switchport nonegotiate
 no cdp enable
 channel-protocol lacp
 channel-group 2 mode active
end

interface GigabitEthernet1/20
 no ip address
 shutdown
 speed nonegotiate
 flowcontrol send off
 switchport
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 100
 switchport mode trunk
 switchport nonegotiate
 no cdp enable
 channel-protocol lacp
 channel-group 2 mode active
end

interface Port-channel2
 no ip address
 switchport
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 100
 switchport mode trunk
 switchport nonegotiate
End

3750:
interface GigabitEthernet0/27
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 100
 switchport mode trunk
 switchport nonegotiate
 speed nonegotiate
 no cdp enable
 channel-group 3 mode active
end

interface GigabitEthernet0/28
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 100
 switchport mode trunk
 switchport nonegotiate
 speed nonegotiate
 no cdp enable
 channel-group 3 mode active
end

interface Port-channel3
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 100
 switchport mode trunk
 switchport nonegotiate
end
