layer 2 link-aggregate not working

[AceofSpace]

Hi, I'm trying to set up a simple 2 port ethernet link-aggregated group and am running into issues passing traffic. My goal is a simple 2 port aggregate that goes to a macbook in our environment (2 x 10GbE ATTO Nics). VLAN 1955 is already set up and passing traffic just fine on all the other non-aggregate interfaces. When I set this up, the device doesn't grab DHCP and upon a static IP assignment, it connects and can ping, but as soon as any sort of file / share traffic is passed it doesn't want to move packets. 

interface Bridge-Aggregation4
description Michael-MacBook
port access vlan 1955
link-aggregation selected-port maximum 2
lacp edge-port
link-aggregation lacp traffic-redirect-notification enable

interface Ten-GigabitEthernet1/0/31
port link-mode bridge
port access vlan 1955
jumboframe enable 9000
port link-aggregation group 4

interface Ten-GigabitEthernet1/0/32
port link-mode bridge
port access vlan 1955
jumboframe enable 9000
port link-aggregation group 4

Anything that sticks out? Switch is a 5940

Thanks.

So I guess I have 3 questions:

1 - is my config ok?

2 - why wouldn't dhcp be working properly all of a sudden on those 2 ports?

3 - when traffic is passed over the 2 link aggregated ports off the client side, file transfers over the network crawl (500kbps). Maybe this might help someone identify the issue?

link-aggregatopm mode dynamic did the trick!

All working as it should now.
