Need DHCP related help with 1131AG

Hi,

I have a 1131AG-K9 AP which gets an IP address from our central DHCP server. I also have it broadcasting a SSID but what I would like to happen is whenever a wireless client connects to the AP, I want them to receive a 192.16.x.x IP. Also, that 192.168.x.x network should not be able to access our production network. Effectively creating a small workgroup with 192.168 IP's and a WEP key.

Here is the config so far.

Thanks in advance.

Re: Need DHCP related help with 1131AG

Hi Sudip,

I think the BVI is on the different Vlan.. is that rite? i mean its not using vlan 192.. am i correct??

If so,then..

Please move the DHCP pool to the switch.. there are some issues if the BVI is on different subnet and if you are using some other subnet for clients for users and having internal DHCP pool for it..

Please check the below link..

http://www.cisco.com/en/US/docs/wireless/access_point/12.3_7_JA/configuration/guide/s37adm.html#wp1090319

Now the config should be..

>> Move the DHCP pool onto the switch..

>> Make the link between the AP and the Switch as a trunk port allowing vlan 192.

Now try connectivity..

Surendra

Re: Need DHCP related help with 1131AG

Hi Sudip,

You want the wireless clients connecting to SSID NYO_Crestron to grab IP in the range 192.168.x.x.Configure the vlan for 192.168.x.x as access vlan on the switchport connected to AP.

Re: Need DHCP related help with 1131AG

Hi Ritika,

I created a vlan and a DHCP pool. Now how do i attach the DHCP pool to the vlan?

Any client that connects to the AP times out and assigns itself a 169.254.x.x ip.

Thanks.

Re: Need DHCP related help with 1131AG

Hi Sudip,

Under the radio interface the Encryption in not napped to vlan 192.. so the clients are not getting the ip address..

please configure as below..

instead of.

!
encryption key 1 size 128bit 7 !!!!!!!!!!!!!!!!!!!! transmit-key
encryption mode wep mandatory
!


Configure..

En

conf t

int dot11 0

no encryption key 1 size 128bit 7 !!!!!!!!!!!!!!!!!!!! transmit-key

no encryption moce wep mandatory

encryption vlan 192 key 1 128bit 7 !!!!!!!!!!!!!!!!!!!!! transmit-key

encryption vlan 192 mode wep mandatory
end

En

conf t

int dot11 1

no encryption key 1 size 128bit 7 !!!!!!!!!!!!!!!!!!!! transmit-key

no encryption moce wep mandatory

encryption vlan 192 key 1 128bit 7 !!!!!!!!!!!!!!!!!!!!! transmit-key

encryption vlan 192 mode wep mandatory
end

wr

This will do it from CLI.. if you wanna use GUI.. then

AP>> Security >> Encryption manager >> Select the Vlan on top >> Select WEP Encryption >> Mandatory in the Drop down >> Key 1 >> Enter the Key >> Apply.

Now try connecting and let me know how this works out for you!!
