vDS configuration

Hi

I'm trying to configure a new vDS and seem to be having some isses around testing failover on the physical switch port.

My configuration is as follows:

ESXi Host

2x 10Gb SFP cards with one port on each card gong to a dfferent switch

Switches

2 x Cisco C9500-48Y4C stacked with LACP configured on the 2 physical ports.

I've created a LAG group with 2 ports and the Port group for the management VLAN is configured for Route based on IP Hash. I can see that both lins are showing as up but when we shut one of the ports down on the switch to test failover I  lose conenctivity to the host. I assme there's a misconfiguration somewhere so any advice would be appeciated

 

Thanks

Hey, hope you are doing fine
Can you share a screenshot of the vDS configuration?
I would like to see the teaming & failover screen.

Thanks in advance

Hi

 

This is the configuration for the DPG for my management VLAN

These are my settings on the LAG group

Please move the uplinks as standby and try again.


Unused uplinks are not connected, so when the lag becomes unusable the uplinks are not available.

I get this error when trying to do that

Okay, do this:
Remove the LAG on vSphere and put both uplinks as active.

Just to be sure, you are using vSphere 7, right?

Yes, I'm using vSphere 7

I've removed the LAG and I don't have a real need for LACP so thought I would just use LBT and set my teaming to 'route based on physical load'

The main issue that i'm facing is that my hosts are configured to use VMNIC0 and vMNIC5 and i can't get the host to communicate only on VMNIC5. the host sees it as connected but it just won't route traffic. I suspect it is an issue with the configuation on the Cisco switch. I've consoled onto the host and with NIC0 disconnected it's unable to ping the GW

Do you have any VLANs configured on VNIC0 and VNIC5?
