+title: IfConfig
+---
+
+ IfConfig stands for "Interface Configuration". It is used
+to configure, control, and query network interface parameters of your system.
+If you try running this command with no arguments, it will simply display information
+about all network interfaces currently active.
+{% highlight bash %}
+ ifConfig
+{% endhighlight %}
+The output sill resembles something like this, of course it changes from machine
+to machine:
+
+
+en5: flags=8863 UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST mtu 1500
+ ether ac:de:48:00:11:22
+ inet6 fe80::aede:48ff:fe00:1122%en5 prefixlen 64 scopeid 0x8

+ ether f2:18:98:41:74:42
+ media: autoselect
+ status: inactive
+
+ ...
+
+
+
+If you want to view the configuration of all network interfaces, not just the ones currently active, you can use
+flag a.
+{% highlight bash %}
+IiConfig -a
+{% endhighlight %}
+
+If you want to view the configuration of a specific interface, you can specify the name of the interface
+you want to view after the command IfConfig:
+{% highlight bash %}
+ ifConfig ap1
+{% endhighlight %}
+This command will show only the configuration of ap1.
+
+To enable an interface, you can use the command ifConfig with the name of the interface
+you want to enable, followed by the key word up.
+However, enabling or disabling a device, is a privilege reserved for the super user, therefore you also
+have to use the command sudo.
+{% highlight bash %}
+ sudo ifConfig ap1 up
+{% endhighlight %}
+
+To disable an interface, you can follow the same procedure, this time using the key word down.
+{% highlight bash %}
+ sudo ifConfig ap1 down
+{% endhighlight %}
