The active ports for portgroups is showing as zero in ESXi host client ui.

Products

• VMware vSphere ESXi

Issue/Introduction

The active ports shows 0 in host client ui even though when powered-on virtual machines are connected to the portgroup.

The virtual machines should not have any connectivity issues.

Environment

VMware vSphere ESXi 8.x

Cause

This issue is seen in ESXi 8.x, as a cache layer was introduced in host ui , and GetNetworkInfo just returns the cache. The cache is updated by the vmkernel event notification. However, for this particular case/field, there is no vmkernel event notification. Thus the cache is not refreshed, and GetNetworkInfo returns stale info.

Hence, the active ports shows a 0 in host ui.

Resolution

This is a known issue in ESXi version 8.0 which will not have any impact on the virtual machines.

As a workaround, run following command in ESXi host ssh which will manually refresh the network info and reflect active ports in ESXi host client ui:-

vim-cmd hostsvc/net/refresh
