nexus 3k with servers

[Mohamed.Ashraf]

Hello

Kindly find attached file.

I have 2 nexus 3k with vpc connected to servers.

When i configure the vpc under port-channel , i can't ping to server.

Appreciate your feedback.

Thank you

[balaji.bandi]

Can you explain more here? which port-channel is this ? and what physical port the Server connected?

what is the Server (windows ?)  side config ? is this LACP ? or Active-Standby?

[Mohamed.Ashraf]

Hello B.B

Port-chanel 75

connected to Hyper-V

[balaji.bandi]

if you get chance to simulate the issue

can you post

show vpc

show port-channel summary interface port-channel 75

Also, try change from Active to ON (both the nexus and let us know)

channel-group mode on

Hello B.B

Kindly fina attached file.

Hello B.B

The protocol at VMware LACP

I think i must make port-channel Active 

Appreciate your help

[balaji.bandi]

I am confused here or am i reading wrong,

1. First, you mentioned Hyper-V

2. Second, you comment VMWARE? ( do you have vSwitch configured inside VMWARE, is this Exsi or VMWARE Workstation?

Can you explain how is your setup? Physically connected to where?

I have also requested below output from switch. ( i do believe,  you lost connection due that Port-channel not come up ?)

show vpc

show port-channel summary interface port-channel 75

Second, the customer moving servers from Hyper-V to VMware.

Are they in a tagged vlan such as 1100 ?

[balaji.bandi]

Looks good to me as per Switch side, so when you enable vPC is the port-channel still up ?

Make sure you have correct setup on vSwitch side.

[Mohamed.Ashraf]

Hello B.B

I want you to know , When i enable the VPC on port-channel i can't access the server althought when i remove VPC from port-channel that make me access the server.

Appreciate your help

[balaji.bandi]

HAve you checked on the Server connecting the Console and Monitor, what is the status on Esxi  side ?

Can you post you esxi vswitch screen shot to understand better on this issue. we do not see for now any issue on switch side.
