Virtual switch explained | VMware ESXi 1. virtual machine port groups – ports used to connect virtual machines to other VMs or the physical network. 2. VNkernel ports – ports configured with their own IP address, subnet mask and default gateway to allow hypervisor management traffic, vMotion, iSCSI storage access, network attached storage (NAS) access, and vSphere Fault Required Ports for the vCenter Server Appliance 902. The default port that the vCenter Server system uses to send data to managed hosts. Managed hosts also send a regular heartbeat over UDP port 902 to the vCenter Server system. This port must not be blocked by firewalls between the server and the hosts or between hosts. Required Ports for vCenter Server and Platform Services You can run the LDAP service on any port from 1025 through 65535. If this instance is serving as the Microsoft Windows Active Directory, change the port number from 389 to an available port from 1025 through 65535. Windows installations and appliance deployments of Platform Services Controller. Key Concepts of ESXi Networking - VMware Essentials

This table lists TCP and UDP ports required by ESXi: ESXi 7.0 ESXi 6.x ESXi 5.x ESXi 4.x ESXi 3.x ESX 4.x ESX 3.x ESXi 7.0

For internal management network, just create another vSwitch, new management port group and new vmk1 adapter. Imagine you want to use internal management network like this: IP: 10.5.5.5/24; GW: 10.5.5.1; Because we cannot have 2 gateways in default TCP/IP stack, you can define gateway directly on vmk1 (this is supported in ESXi 6.5):

For information about how to open port 2377, see Open the Required Ports on ESXi Hosts. NOTE: If the management network uses DHCP, vic-machine checks the firewall status of the management network before the VCH receives an IP address. It is therefore not possible to fully assess whether the firewall permits the IP address of the VCH.

902. The default port that the vCenter Server system uses to send data to managed hosts. Managed hosts also send a regular heartbeat over UDP port 902 to the vCenter Server system. This port must not be blocked by firewalls between the server and the hosts or between hosts.
