Start a DOS Window:
1. Select Start from the Windows 95 taskbar.
2. Select Programs .
3. Select MS-DOS Prompt .
Issue the PING Command:
In the DOS window, type the command:
ping <IP address>
Example:
ping 192.168.254.254
When you enter the
ping
command, the router will dial out to the
remote router using the ISDN line. ISDN Status LED CH1 or CH2
should go on.
If you cannot contact the router using the ping command:
•
Run the Port Monitor to check the status of the ISDN channels
(Refer to Port Monitor , page 83).
•
If the ISDN link is not in standby mode, verify the target router’s
ISDN configuration, SPIDs and DNs, telephone company
provisioning, associated equipment (NT1, etc.) and cable
connections.
•
If the ISDN line is operational, check the remote router’s telephone
numbers and links parameter.
•
Check that, if required, you specified valid remote WAN IP address
and local WAN IP addresses.
•
Verify the security authentication method and password of the
remote router. Also, the router’s entry must be enabled.
Test Routing from a Remote Destination
Have a remote router contact the target router using a similar method and
verify both ISDN B-channels.
Test TCP/IP Routes
Contact a station, subnetwork or host on the network beyond a remote
router to verify the TCP/IP route addresses entered in the remote router
database.
