Hi,

Can you use the same portchannel id on both links and both sides on the connection

example:"

SW6#show run interface gigabitEthernet 1/1 

!
interface GigabitEthernet1/1
switchport trunk encapsulation dot1q
switchport mode trunk
media-type rj45
negotiation auto
channel-group 26 mode active
end

SW6#show run interface gigabitEthernet 1/2 

!
interface GigabitEthernet1/2
switchport trunk encapsulation dot1q
switchport mode trunk
media-type rj45
negotiation auto
channel-group 26 mode active
end

SW6#show EtherChannel summary

 

Use the same ID on the nexus sides as well and test again
