Question : Connecting an Enterasys C3K122-24 to a Cisco 6509

I have an Enterasys C3K122-24 and a Cisco 6509 and I would like to connect 3 ports in aggregate to 3 ports on the Enterasys.  I set up the lag ports on the Enterasys switch and the port channel on the Cisco, but I must be doing something wrong.  Does anybody have experience with both Cisco and Enterasys switches who can give me some guidance?  

Answer : Connecting an Enterasys C3K122-24 to a Cisco 6509

I may have answered my own question.  After unplugging each of the ports on the Cisco 6509 and plugging them back in the 6509 began passing information on both vlan 1 and vlan 70.

6509 setup:
interface Port-channel70
 description Channel for Trunk
 switchport
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1,70
 switchport mode trunk
 no ip address

interface GigabitEthernet4/46
 description Trunk
 switchport
 switchport trunk allowed vlan 1,70
 switchport mode trunk
 no ip address
 power inline never
 channel-group 70 mode desirable
 spanning-tree cost 100

interface GigabitEthernet4/47
 description Trunk
 switchport
 switchport trunk allowed vlan 1,70
