The vSwitch can route traffic internally between virtual machines and link to external networks. You can also configure a vSwitch to handle physical NIC failover. The vSwitch can be configured in the following scenarios:

• Configuring vNetwork Standard Switch Without Physical NIC Redundancy
  
• Configuring vNetwork Standard Switch With Physical NIC Redundancy
  

Configuring vNetwork Standard Switch Without Physical NIC Redundancy

You must configure virtual network interface cards (vNICs) on the

from mapping of physical interfaces to vSwitches. The recommended configuration is to have vNICs on the different vSwitches as shown below.

Configure vSwitch in the following order:

• First Ethernet interface for management (MGMT)
• Second Ethernet interface for HA (HA)
• Third and fourth Ethernet interface for Media (PKT0 and PKT1)

To configure the vSwitch, perform the following steps:

1. Login as user root on VMware vSphere client.

   1. Enter VM Ware host machine IP Address.
   2. Enter your VMware vSphere administrator user name.
   3. Enter your VMware vSphere administrator password.

   1. Add a New Virtual Interface and vSwitch0 (MGMT).

      1. Select Use vSwitch0. The vmnic0 is automatically selected. Make sure that the speed is showing 1000 Full for the selected vSwitch. It indicates physical port is up. Click Next.

         Note
         If the VLAN is used for packet ports (PKT 0 or PKT1), then the VLAN ID (optional) parameter must be selected as ALL (4095). This method is recommended and it is called as VGT (Virtual Guest tagging), where the guest OS takes care of VLAN tagging functionality. The VLAN can be used for either PKT0 or PKT1 or both. For non-VLAN configuration, use the default value 0.

   5. Verify that the added vSwitches are in proper order. Click Configuration tab and Networking.

      Warning
      The switches and interfaces MUST be defined in this order: vSwitch0 - MGMT vSwitch1 - HA vSwitch2 - PKT0 vSwitch3 - PKT1

      Note
      Usage of vSwitch0 is not a mandatory requirement for MGMT0 interface. If server has more than 4 physical NIC ports, there is an option to assign MGMT label to vSwitch1, HA to vSwitch2, PKT0 to vSwitch3 and PKT1 to vSwitch4.

Configuring vNetwork Standard Switch With Physical NIC Redundancy

To protect the NIC failures, each vSwitch is configured with active and standby up-link adapters (physical NICs) using the NIC teaming feature of the VMware. To support this redundant configuration, ensure there is a minimum of eight physical NIC ports on the box. This configuration for high end system with full NIC protection as shown:

NIC Teaming Configuration

NIC teaming allows you to group two or more physical NICs into a single logical network device called a bond. Once a logical NIC is configured, the virtual machine is not aware of the underlying physical NICs. Packets sent to the logical NIC are sent to one of the physical NICs in the bond and packets arriving at any of the physical NICs are automatically directed to the appropriate logical NIC.

To configure, perform the following steps:

1. Make sure the physical host server is configured with minimum 8 physical NIC ports to have 1:1 physical NIC redundancy for each vNICs (that is MGMT0, HA0, PKT0 and PKT1 virtual interfaces) on

2. Repeat sub steps of Step 3 shown in Configuring vNetwork Standard Switch Without Physical NIC Redundancy

3. Add additional NICs and group it by using the following steps:
