Hi,
Have a 6509 running native 12.1(8b)15. trying to L3 channel group too a layer 2 using switch mode and vlans. Can channel two ports on same blade but cannot channel across different blades e.g.
3/3 & 3/4 ok
3/4 & 4/4 not ok
get error message:
Command rejected (Port-channel2): Cannot configure L2 interfaces across DFC cards
hardware:

example config for channel group:
!
interface Port-channel2
no ip address
switchport
switchport access vlan 2
switchport mode access
!
interface GigabitEthernet3/4
no ip address
switchport
switchport access vlan 2
switchport mode access
channel-group 2 mode desirable
!
!
interface Vlan2
ip address 2.2.2.2 255.255.255.0
no ip redirects
no mop enabled
no mop sysid
This does however work on another device. Difference being the Native IOS ver and Line cards:
IOS Version 12.1(8a)E5
Line Card: 3 16 SFM-capable 16 port 1000mb GBIC WS-X6516-GBIC SAD054502YC
Cheers, John.
