The following example creates an ARP table entry for IP address 192.168.1.10 and MAC
address 01:02:03:04:05:06. Then it shows the ARP table and finally removes the new entry.
The following examples show how to configure packet capture settings and perform a packet
capture. First you have to check whether a packet capture is running. This example shows no
other packet capture is running. Then you can also check the current packet capture settings.
