Creating vSwitches, Port Groups and assigning VLAN IDs

Add a physical NIC uplink to a virtual Switch:

esxcfg-vswitch -L  
eg: esxcfg-vswitch -L vmnic1 vSwitch0 (adds the uplink of vmnic1 to vSwitch0)

Create a Virtual Switch:

esxcfg-vswitch -a vSwitch1

Create portgroup on virtual switch:

esxcfg-vswitch -A NewPortGroup vSwitch0

Add a VLAN ID to a port group: (VLAN ID 101 to NewPortGroup on vSwitch0)

esxcfg-vswitch -v 101 -p NewPortGroup vSwitch0

Unlink a physical NIC to a virtual switch:

esxcfg-vswitch -U vmnic1 vSwitch0

Link a physical NIC to a virtual switch:

esxcfg-vswitch -L vmnic1 vSwitch0

Add VMotion vmkernel portgroup

esxcfg-vswitch -A VMkernel  vSwitch0

esxcfg-vmknic -a -i 192.168.0.100 -n 255.255.255.0 VMkernel

esxcfg-route 192.168.0.254
