->If the network interface has multiple IP configurations, the forth command must be done for all these IP configurations before the final Set-AzNetworkInterface command is executed. This can be done as in the forth command but by replacing "0" with the appropriate number. If a network interface has N IP configurations, then N-1 of these commands must exist.

-The first command gets an existing network interface called NetworkInterface1 and stores it in the $nic variable. The second command gets an existing network security group called MyNSG and stores it in the $nsg variable. The third command assigns the $nsg to the $nic. Finally, the forth command applies the changes to the Network interface. To dissociate network security groups from a network interface, simple replace $nsg in the third command with $null.
