I am more familiar with firewalls and this is my first wireless device, so I have a few questions.

The 1130AG is a router, correct?

How in the he!! do you configure the DHCP for the wireless side? The documentation on this is very very lacking!! What I found is listed at the end of this posting. My questions are:

A. For the “network <AP Network>" setting, is this a different IP address than the wired port IP address?
If it is different, does it need to be in the same subnet as the wired port?

B. For the default router, I guess this depends on the answer to A. If the ip address set is different than the wired port, what do I set for the default gateway if all I want is to have all traffic from the wireless clients passed to the wired port?


Cisco needs a much better write up and example for this.

Thanks in advance,
Bob


From
Step 1 Enter configuration mode at the Cisco IOS CLI.

Step 2 Create the DHCP pool, including the necessary parameters such as default router and name server. A DHCP scope example is as follows:

ip dhcp pool <pool name>
network <IP Network> <Netmask>
default-router <Default router>
dns-server <DNS Server>

Step 3 Add the option 60 line using the following syntax:

option 60 ascii "VCI string"
For the VCI string, use the value from Table G-1. The quotation marks must be included.

Step 4 Add the option 43 line using the following syntax:

option 43 hex <hex string>
The hex string is assembled by concatenating the TLV values shown below:

Type + Length + Value

Type is always f1(hex). Length is the number of controller management IP addresses times 4 in hex. Value is the IP address of the controller listed sequentially in hex.

For example, suppose that there are two controllers with management interface IP addresses, 10.126.126.2 and 10.127.127.2. The type is f1(hex). The length is 2 * 4 = 8 = 08 (hex). The IP addresses translate to 0a7e7e02 and 0a7f7f02. Assembling the string then yields f1080a7e7e020a7f7f02. The resulting Cisco IOS command added to the DHCP scope is listed below:

option 43 hex f1080a7e7e020a7f7f02
