link aggregation from cisco 3020 blade switch, through cascaded 3750Gs to Netapp FAS 3020c filers

Hi All,

Firstly I must apologise, my knowledge of cisco is extremely lacking so please try to be gentle :) Any help would be MUCH appreciated.

Ive placed a visio of how we would like to configure our switches here,
http://webuser.a4e.co.uk/linkagg.vsd
each black line signifies 2 ethernet cables, i have drawn them as one to avoid cluttering the diagram

I am trying to configure both the cisco 3750s which are cascaded btw and the cisco 3020 blade switches for link aggregation to allow effectively 16 gb between the filer and the blade system (which is hp c class populated with bl460s)
The Blades are connected to the 3750s via two 3020 blade switches, then each 3750 (which are cascaded) is in turn connected to the two netapp filers, where each filer has a vif setup with one ip address assigned to a vif containing 8 ports each that we are looking to aggregate (8 ports to each filer = 16 ports contained within 2 vifs). Hope the diagram makes it clear. The vifs are setup on the netapp filer end so it is mainly how to configure both the ciscos to aggregate the 16 ports from the blade switches and aggregate the 16 ports to the filer.

From initial research, on the 3750s, Ive tried to put together a config but its probably way off the mark (sorry)

(config)Vlan2

(config)int po 1
(config-if-po 1) switchport access vlan 2
(config-if-po 1)switchport mode trunk
(config-if-po 1)switchport trunk encapsulation dot1q
(config-if-po 1)Switchport trunk allow vlan 2
(config-if-po 1)no shut

(config)int range gi 1/0/1-8
(config-if-range)#descrip Bladeconnsw1
(config-if-range)#switchport mode trunk
(config-if-range)#switchport trunk encapsulation dot1q
(config-if-range)#spanning-tree portfast
(config-if-range)#speed auto
(config-if-range)#duplex auto
(config-if-range)#channel-group 1 mode active
(config-if-range)#shut
(config-if-range)#no shut

(config)int po 2
(config-if-po 2) switchport access vlan 2
(config-if-po 2)switchport mode trunk
(config-if-po 2)switchport trunk encapsulation dot1q
(config-if-po 2)Switchport trunk allow vlan 2
(config-if-po 2)no shut

(config)int range gi 2/0/1-8
(config-if-range)#descrip Bladeconnsw2
(config-if-range)#switchport mode trunk
(config-if-range)#switchport trunk encapsulation dot1q
(config-if-range)#spanning-tree portfast
(config-if-range)#speed auto
(config-if-range)#duplex auto
(config-if-range)#channel-group 2 mode active
(config-if-range)#shut
(config-if-range)#no shut

(config)int po 3
(config-if-po 3) switchport access vlan 2
(config-if-po 3)switchport mode trunk
(config-if-po 3)switchport trunk encapsulation dot1q
(config-if-po 3)Switchport trunk allow vlan 2
(config-if-po 3)no shut

(config)int range gi 1/0/17-24
(config-if-range)#descrip netapp
(config-if-range)#switchport mode trunk
(config-if-range)#switchport trunk encapsulation dot1q
(config-if-range)#spanning-tree portfast
(config-if-range)#speed auto
(config-if-range)#duplex auto
(config-if-range)#channel-group 3 mode active
(config-if-range)#shut
(config-if-range)#no shut

(config)int po 4
(config-if-po 4) switchport access vlan 2
(config-if-po 4)switchport mode trunk
(config-if-po 4)switchport trunk encapsulation dot1q
(config-if-po 4)Switchport trunk allow vlan 2
(config-if-po 4)no shut

(config)int range gi 2/0/17-24
(config-if-range)#descrip netapp
(config-if-range)#switchport mode trunk
(config-if-range)#switchport trunk encapsulation dot1q
(config-if-range)#spanning-tree portfast
(config-if-range)#speed auto
(config-if-range)#duplex auto
(config-if-range)#channel-group 4 mode active
(config-if-range)#shut
(config-if-range)#no shut

port-channel load-balance src-dst-ip

*Note - The vifs are only capable of 802.3ad and need to use lacp

And then for the 3020 blade switches, (config on each as)

(config)int po 1
(config-if-po 1) switchport access vlan 1
(config-if-po 1)switchport mode trunk
(config-if-po 1)switchport trunk encapsulation dot1q
(config-if-po 1)no shut

(config)int range gi 1/0/17-24
(config-if-range)#descrip 3020agg
(config-if-range)#switchport mode trunk
(config-if-range)#switchport trunk encapsulation dot1q
(config-if-range)#spanning-tree portfast
(config-if-range)#speed auto
(config-if-range)#duplex auto
(config-if-range)#channel-group 1 mode active
(config-if-range)#shut
(config-if-range)#no shut

Any advise, help or general guidance is much appreciated.

Thanks,
