Troubleshooting DHCP IP Addresses
Your router is acting as a DHCP client
If your router is acting as a DHCP client the router should receive its IP address
dynamically. If your router is not receiving an IP address, check that the
domain name and host name are correct.
Your router is acting as a DHCP server
If your router is not assigning IP addresses to a host, or hosts, on the subnet
perform this procedure:
1. Reboot the host machine, to force it to re-request IP settings.
2. Check the host’s TCP/IP settings.
In Microsoft® Windows™ 95/98, click Settings → Control Panel →
Network
. Select TCP/IP and click Properties. Click Obtain an IP address
automatically .
In Microsoft® Windows™ 2000, click Settings → Control Panel →
Network and Dial-up Connections
→ Local Area Connection →
Properties . Select Internet connection (TCP/IP) and click Properties. Click
Obtain an IP address automatically .
3. Check that the DHCP server has a large enough range of addresses. To
assign a range, enter the command:
CREATE DHCP RANGE
Troubleshooting IPX Configurations
No Routes are Visible to the Remote Router
1. Check the PPP link
To check that the PPP link is active, enter the command:
SHOW PPP
The display should look like that shown in Figure 25 on page 132. The state
of the IPX control protocol (IPXCP) should be “OPENED”. If not, then the
fault lies with the connection between the two routers, or the PPP
configuration at either end of the link.
Figure 25: Example output from the SHOW PPP command for a basic Novell IPX network.
To interpret output from the SHOW PPP command see the Point-to Point
(PPP) chapter in the Software Reference.
