Cisco Nexus 3064 and C3750 PortChannel issues

[mehtaamitm1]

Hi,

I have two 3064 switch deployed VPC, connected to a single C3750 via port-channel. On both Nexus port eth1/45 is connected to 3750 te1/1/1 and te1/1/2 and port channel is up. The problem is i am unable to ping hosts connected to both nexus from hosts connected to C3750 and vice versa, even switch  to switch ping is not working. I have attached the config of all three switches. I am lost and not able to understand what could be the problem. If someone can help me on this.

Thanks and Regards,

Amit

Hi @mehtaamitm1 

From what I see, there is no vlan config on 3750, so I suppose you have VTP configured. Do you have VTP pruning enabled? if yes, then this might be the issue.

Note that Nexus switches do not support VTP. I mean it does support vtp transparent mode, but I would suggest you do not enable VTP on Nexus switches.

Stay safe,
