I'm trying to bond two interfaces together on my filer, to create a 2Gb link. They connect to a Cisco 3750. On the Cisco side I setup a port channel, and added the two physical ports to it. On the NetApp side I added those two interfaces to a vif. On the Cisco side both ports show up and active, and traffic is flowing just fine.
But I'm noticing that I often spike 1 physical interface to nearly 100% (960Mbs), and the other interface never shows any traffic. It seems like I'm peaking at 1Gbs, and the second link is never being used.
Is there anything I should look at to confirm my port channel is setup correctly for load balancing? Here's my Cisco config:
interface Port-channel1
description netapp-vif01
switchport mode access
!
interface Port-channel2
description netapp-vif02
switchport mode access
!
interface GigabitEthernet1/0/2
description netapp-e0a
switchport mode access
channel-group 1 mode active
!
interface GigabitEthernet1/0/3
description netapp-e0b
switchport mode access
channel-group 1 mode active
!
interface GigabitEthernet1/0/4
description netapp-e0c
switchport mode access
channel-group 2 mode active
!
interface GigabitEthernet1/0/5
description netapp-e0d
switchport mode access
channel-group 2 mode active
!
Thanks!
