UCS I/O Module 2104 connectivity

Nkechi Latunji

Hello,

I am experiencing connectivity issues in my UCS environment. An ESXi host with vnic0 connected to I/O Module 1 (2104) and vnic1 to I/O Module 2 is having connectivity issues to rest of network. When I remove vnic1 from the host, IP connectivity is restored. Attempting to use only vnic1 and not connecting vnic0 to the vswitch cause loss of IP connectivity to the hosts. I have tried Active/Standby, Active/Active configurations on the vswitch and same results when I connect vnic1.

Can someone please tell me what I should be looking for in the UCS environment or how I can fix this problem please.

Thank you

Make sure you have allowed the same vlan that you are using for mgmt on vnic 1 too
