I am trying to bring up a trunk between a 3750G stack and (2) Nexus 3048. The uplinks on the 3048's are using 1gig MM SFP. The ports on the 3750 stack are configured as a port channel. I have checked the SFPs, they are valid. I had swapped out fiber patch cables, SFPs. I have included the configurations below, so any help is appreciated!
Configuration on the 3750 stack:
!
interface GigabitEthernet4/0/7
description ***To C1R2NX3048-1***
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,255
switchport mode trunk
channel-group 11 mode active
end
!
interface GigabitEthernet5/0/7
description ***To C1R2NX3048-2***
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,255
switchport mode trunk

end
!
interface Port-channel11
description *** To C1C2NX3048***
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,255
switchport mode trunk
end
