Figure 8-3. How the Remote Client Receives WINS Server Information from the Access Server
Assigning WINS Addresses
If you enable DHCP on the access server, it receives the WINS server addresses
from a DHCP server on the network and writes the values to VRAM when you
reinitialize the access server. When a remote client sends a request to the access
server for WINS server addresses during PPP negotiation, the access server
responds with the addresses it finds in VRAM.
If you disable DHCP, or need to change the WINS server addresses at a time when
you do not want to reinitialize the access server, you can set the addresses
manually. Use the SET/DEFINE/CHANGE INTERNET WINS
[PRIMARY|SECONDARY] command for this purpose.
WINS Address Example
The following example shows how to set primary and secondary WINS server
addresses on the access server:
Local> CHANGE INTERNET WINS PRIMARY 12.30.34.10
Local> CHANGE INTERNET WINS SECONDARY 12.150.25.5
Displaying WINS Characteristics
Use the SHOW/LIST INTERNET NAME RESOLUTION command to view the
WINS server addresses stored in the access server’s VRAM (or NVRAM).
Dial-Up Client
1.Client requests
WINS server
addresses
during PPP
negotiation.
3. Client sends
new request
using the
addresses it
recieved from the
access server.
2. Server receives
request. Sends
addresses
stored in VRAM.
Access Server
4. Access Server
compares request
to addresses in
VRAM. If they
match, sends an
acknowledgement.
If no match, sends
new addresses.
5. Client receives
acknowledgement.
PPP negotiation
continues.
