C3750 Software (C3750-ADVIPSERVICESK9-M), Version 12.2(44)SE1, RELEASE
SOFTWARE (fc1)
Running two etherchannels with two gig ports not cross stack. Here's an
example of one of them.
What's happening is that only one port is being used for outgoing
traffic, no matter what I set the port-channel load-balance to. Is
etherchannel broken in 12.2.44SE1? This is a new setup.

interface GigabitEthernet1/0/1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 5,11
switchport mode trunk
load-interval 30
channel-group 1 mode active
end
interface GigabitEthernet1/0/2
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 5,11
switchport mode trunk
load-interval 30
channel-group 1 mode active
end
interface Port-channel1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 5,11
switchport mode trunk
load-interval 30
end
