- The vCenter UI displays six port groups on host CS####31, whereas only three are visible on host CS####32
- Configuration snippet for host -- CS####32
- Configuration snippet for host -- CS####31
- Reviewed the healthy ESXi host (CSDESX31) and noted that its VMkernel adapters are assigned to the networks listed below. However, there are no VMKs mapped to the "Backup" or "vCenter" networks.
Host -- CS####31

- But for the problematic esxi host "CS####32" we notice VMK3 & VMK4 is mapped to "Backup & vCenter".

- Observed discrepancies in the standard vSwitch/port group configurations when comparing the two ESXi hosts [CS####31 & CS####32 ].
Remove the extraneous vmkernel adapters (vmk3 and vmk4) from the second host and recreating the affected port groups.
