Here are maintenance tool commands that you can use in configure mode.

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.

46.1.1 Packet Capture Command Example

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.

Then configure the following settings to capture packets going through the ZyWALL’s WAN1
interface only.

Router# traceroute www.zyxel.com
