+== Connect ESX Host To Cisco Switch With Gigabit !EtherChannel ==
+
+The `vSwitch0` virtual switch was created during installation of ESX software on the host. Service concole port (`vswif0`) and the "VM Network" port group are both connected to this switch. In **vSphere Client** (//Configuration > Networking//) default setup will be depicted like this:
+
+[[Image(vSwitch0-00.png)]]
+
+The same information can be displayed from the command line on ESX host as well.

+First will add a VMkernel port group and configure its IP settings (required for VMotion).

+To configure //NIC Teaming// will use the **vSphere Client**.
+
+[[Image(vSwitch0-02.png)]]
+
+In **vSwitch0 Properties** open the **NIC Teaming** tab, and choose the //"Route based on IP hash"// option for **Load Balancing**, and also choose //"No"// for **Fallback**. On the **General** tab one can adjust number of ports supported by the virtual switch. In the latter case reboot will be required for this new setting to take effect.

+
+On a **Cisco C2960** switch configure static (without PAgP or LACP) four-port 802.3ad channel group (interfaces Gi0/13 thru Gi0/16 are all configured identically).
