Utilities for network debugging
The console interface provides several utilities to assist the Administrator to check the system conditions
and to debug any problems. The utilities are described as follow:
Ping host (IP): By sending ICMP echo request to a specified host and wait for the response to test
the network status.
Trace routing path: Trace and inquire the routing path to a specific target.
Display interface settings: It displays the information of each network interface setting including the
MAC address, IP address, and netmask.
Display the routing table: The internal routing table of the system is displayed, which may help to
confirm the Static Route settings.
Display ARP table: The internal ARP table of the system is displayed.
Display system up time: The system live time (time for system being turn on) is displayed.
Check service status: Check and display the status of the system.
Set device into "safe mode": If administrator is unable to use Web Management Interface via the
browser for the system failed inexplicitly. Administrator can choose this utility and set AMG-2000
into safe mode, then administrator can management this device with browser again.
Synchronize clock with NTP server: Immediately synchronize the clock through the NTP protocol
and the specified network time server. Since this interface does not support manual setup for its
internal clock, therefore we must reset the internal clock through the NTP.
Print the kernel ring buffer: It is used to examine or control the kernel ring buffer. The program helps
users to print out their bootup messages instead of copying the messages by hand.
Main menu: Go back to the main menu.
Change admin password
Besides supporting the use of console management interface through the connection of null modem, the
system also supports the SSH online connection for the setup. When using a null modem to connect to
the system console, we do not need to enter administrator's password to enter the console management
interface. But connecting the system by SSH, we have to enter the username and password.
The username is "admin" and the default password is also "admin", which is the same as for the web
