Hi,
we are fighting with an 40 Gbps etherchannel between 2 Nx 5000 and 2 Catalyst 6500 but the etherchannel never comes up. Here is the config:
NK5-1
interface port-channel30
description Trunk hacia VSS 6500
switchport mode trunk
vpc 30
switchport trunk allowed vlan 50-54
speed 10000
!
interface Ethernet1/3
switchport mode trunk
switchport trunk allowed vlan 50-54
beacon
channel-group 30
!
interface Ethernet1/4
switchport mode trunk
switchport trunk allowed vlan 50-54
channel-group 30
NK5-2
interface port-channel30
description Trunk hacia VSS 6500
switchport mode trunk
vpc 30
switchport trunk allowed vlan 50-54
speed 10000
!
interface Ethernet1/3
switchport mode trunk
switchport trunk allowed vlan 50-54
beacon
channel-group 30
!
interface Ethernet1/4
switchport mode trunk
switchport trunk allowed vlan 50-54

Hi,
I have got two DCs. Each DC has a pair or 5596. We have setup VPC Peering within each DC between two 5596s
Now I need to connect two DCs to each other. I have connected them like normal trunk ports. Is it possible If I can connect them together as etherchannel using VPC at both ends. VPC domain at both DCs is different.Is it possible to make 2 10gbps links one.
.
Regards

Hi,
first you need configure LACP mode active in VSS-N5k Port-Channel side and active or pasive in N5K-VSS.
Be sure that the vPC domain in N5K is different that the VSS domain.
The N5K has Bridge Assurance activated by default, therefore you has two ways:
Configure both Port-Channels with "spanning-tree port type network", this is the Bridge Assurance mode or
Configure N5K Port-Channel with "spanning-tree port type normal".
We have it configured and working.
I hope I've helped.
