In this case, a host do not compare source and effective MAC which are transmitted from a VM.If security policy MAC Address Changes is set to Accept, then new Effective MAC address will be agree to Initial MAC and it will be automatically updated in ARP table and Virtual Machine will work as usual.If security policy MAC Address Changes is set to Reject, then Initial Address and Effective Address will not agree with each other and it will result that Port will be administratively down.If the guest OS changes the Effective Address, the port will compare the Effective Address to the Initial Address. Virtual MachineвЂ™s Initial Address and Effective Address must agree with each other.Now, due to any reason you changed the MAC address of Virtual machine and Effective MAC address get change to 00:50:56:AF:3C:EH. LetвЂ™s take an example, you have a Virtual machine with Initial MAC address 00:50:56:AF:3C:FG.

Sometimes you put a manual MAC address in a VM, that is a effective MAC. The effective MAC address is included in network communication as the source MAC of the virtual machine. Effective MAC вЂ“ It is configured by the guest operating system that is used during communication with other virtual machines.Guest OS has no control over the initial MAC Address. Initial MAC вЂ“ It is generated automatically and that resides in the configuration file(VMX file).All virtual machines have two MAC addresses:.MAC Address Changes is concerned with incoming traffic.If it is in accepted mode, then host accepts requests to change the effective MAC address to different one than the original.This security policy is enabled by default in standard switch and disabled in Distributed Switch.But if you set it to accept mode, than it will transfer the traffic to both PG-A and PG-B and itвЂ™s VM-1, VM-2, VM-3, VM-4.If Promiscuous mode is set to Reject, PG-A and PG-B will not send traffic across and will only deliver packet as point to point delivery.In PG-B, we have another two Virtual machines as VM-3 and VM-4.

In PG-A, we have two Virtual Machines as VM-1 and VM-2.

LetвЂ™s take an example that we have two port groups PG-A and PG-B.

By default, this policy is set to Reject on virtual switches (standard or distributed).

However, promiscuous mode can be explicitly disabled at one or more portgroups within the vSwitch.

When promiscuous mode is enabled at the virtual switch level, all portgroups within the vSwitch will default to allowing promiscuous mode.When promiscuous mode is enabled at the portgroup level, objects defined within that portgroup have the option of receiving all incoming traffic on the vSwitch.If you change to accept then the guest OS can recieve all traffic which passes through the vSwitch or portgroup.It can be defined at Virtual Switch or Port Group level.VSphere Standard Switch has following Network Policies: Select Virtual Switch and Click on Pencil icon to Edit.Click on host and go to Networking under Configure Tab.Login to vCenter server using Web client.You can also apply same network policies for all port groups or standard switch.You can create multiple port groups in a standard switch, and then you can apply different policies at each port groups.Standard Switch policies are configured for enhancing the security of complex virtual environment in a better way.In this section, we are going to explore Configuring virtual switch security, traffic -shaping and load -balancing policies.

In last section, we learnt the concepts of vSphere Standard Switch and How to Create a vSwitch in a vSphere Environment.

What is MTU (Maximum Transmission Unit).

Continuing to vSphere 6.7 Install, Configure, and Manage modules, today we are going to cover vSphere networking which is one of the tough parts to know for VMware admins and have lot of difficulties while applying the network policies.
