Post subject:  L3 to L2 port-channel with IOU

Is there anyway to create a port-channel between the L3 IOU and the L2 IOU? I can't make it work. I can't even issue the "switchport" command on the L3 IOU. I want to have L3 IOU's doing my routing and want to have L2 port channels down to my access layer IOU devices (L2). Any ideas? I don't think GNS3 1.0 is ready to replace real gear yet, they need to do A LOT more work on this....

L2IOU supports most of the routing features also. A basic lab can be created with the following configuration that includes:

- L2 EtherChannel with LACP
- 802.1Q
- EIGRP (Named Mode)

Code:
!! L3IOU (i86bi-linux-l3-adventerprisek9-15.4.1T.bin)
! Set interfaces
int lo0
  ip addr 1.1.1.1 255.255.255.255
  exit
int e1/0
  ip addr 10.0.0.1 255.255.255.0
  no shut
  exit
! Configure dynamic routing
router eigrp gns3
  address-family ipv4 autonomous-system 1
   network 1.1.1.1 0.0.0.0
   network 10.0.0.1 0.0.0.0
   af-interface lo0
    passive-interface
    exit-af-interface
    end

!! L2IOU1 (i86bi-linux-l2-adventerprise-15.1b.bin)
! Create VLAN 100
vlan 100
  exit
! Set interfaces
int lo0
  ip addr 2.2.2.2 255.255.255.255
  exit
int e1/0
  no switchport
  ip addr 10.0.0.2 255.255.255.0
  no shut
  exit
int range e0/0-3
  switchport trunk encap dot1q
  switchport mode trunk
  channel-protocol lacp
  channel-group 1 mode active
  no shut
  exit
int po1
  switchport trunk encap dot1q
  switchport mode trunk
  exit
int vlan100
  ip addr 10.0.100.1 255.255.255.0
  no shut
  exit
! Configure dynamic routing
router eigrp gns3
  address-family ipv4 autonomous-system 1
   network 2.2.2.2 0.0.0.0
   network 10.0.0.2 0.0.0.0
   network 10.0.100.1 0.0.0.0
   af-interface lo0
    passive-interface
    exit-af-interface
   af-interface vlan100
    passive-interface
    exit-af-interface
    end

!! L2IOU2 (i86bi-linux-l2-adventerprise-15.1b.bin)
! Create VLAN 100
vlan 100
  exit
! Set interfaces
int range e0/0-3
  switchport trunk encap dot1q
  switchport mode trunk
  channel-protocol lacp
  channel-group 1 mode active
  no shut
  exit
int po1
  switchport trunk encap dot1q
  switchport mode trunk
  exit
int e1/0
  switchport mode access
  switchport access vlan 100
  no shut
  end

!! VPCS
! Set interface
ip 10.0.100.10 /24 10.0.100.1

save
