PowerShell adds a reserved address in bulk through variables and arrays

PowerShell adds a reserved address in bulk through variables and arrays

Our last article introduced the simple management of DHCP scopes via PowerShell, and today describes the use of PowerShell-defined variables and arrays for bulk add reserved IP address information under DHCP scopes, as shown below:

We will first use the Get-content file path to read the local files and then use the variables to get the local files. After reading the contents of the local file, the data of each row is executed through a foreach loop, and each line defines multiple data, all of which need to be done using an array, whether the script above starts with [0] and then configures the command to complete the operation.

The first is to define the local text data information

127.0.0.1 Management IP for DHCP server

10.10.10.0 scope information for DHCP server

10.10.10.X for reserved IPs that need to be added under the DHCP server scope

XXXXXXXX. X is the MAC address of the reserved IP that needs to be added under the DHCP server scope

Names display name reserved for DHCP

DESC description information reserved for DHCP

The next step is to define the script.

$file =get-content D:\test.txtforeach ($line in $file) {$vars = $line-split "," $serverip = $vars [0] $n = $vars [1] $ip = $vars [2 ] $m = $vars [3] $resername = $vars [4] $desc = $vars [5]netsh DHCP server $serverip scope $n add reservedip $ip $m "$resername" $de SC "" BOTH "}

Start execution and execution success
