cisco 891w universal workgoup bridge mode

Hi guys.

I'm configuring cisco 891w universal workgroup group bridge mode to non-cisco access point (MAC c24a.0040.9f36). This non-cisco access point has no filtering or other limitations. (it just performing WPA2/PSK)

c891w router and access point module configuration attached.

c891w access point module successfully associated & authenticated with non-cisco access point

where MAC 00ed.b184.2174 is access point BVI70

++++++++++++++++++++
gate-ap#sh int bvi70 | i up|bia
BVI70 is up, line protocol is up
Hardware is BVI, address is 00ed.b184.2174 (bia 2c54.2dba.136e)

So. I assume. logical interconnection between router and access point modules setup correctly.

My goal is:

Get assigned IP from non-cisco access point to router module interface vlan 70

but whenever I unassigned bvi70 DHCP IP and hopping to get IP assigned to router module interface vlan70 but unfortunately it did not happen :

gate-ap(config-if)#no ip address

*Mar 1 00:52:10.479: %DOT11-4-NO_SSID_VLAN: No SSID with VLAN configured. Dot11Radio0 not started.
gate-ap(config-if)#ssid a81m-guest
*Mar 1 00:52:17.995: %LINEPROTO-5-UPDOWN: Line protocol on Interface Dot11Radio0, changed state to up

gate-ap(config-if)#
++++++++++++++++++++

router module:

++++++++++++++++++++
gate#sh ip int bri | i lan
Vlan1 10.2.2.1 YES NVRAM up up
Vlan10 192.168.174.1 YES NVRAM up up
Vlan60 192.168.174.33 YES NVRAM up up
Vlan70 unassigned YES DHCP up up
Wlan-GigabitEthernet0 unassigned YES unset up up
wlan-ap0 10.1.1.1 YES NVRAM up up
gate#
++++++++++++++++++++

Could somebody suggest what I'm doing wrong? Unfortunately I red I lot of documentations in internet but did not find similar to my issue ones. (support forum has a lot of broken links now?)
W implemented similar configuration could you help?

Thank you.

Re: cisco 891w universal workgoup bridge mode

Thank you Flavio.

 

Not-cisco AP has assigned IP address to c891w access point module (l2 switch) bvi interface but cannot assign IP to c891w router module l3 interface  (vlan 70 in this case)

 

Router schema attached. So do you think access point module configuration preventing DHCP replays from DHCP server behind non-cisco AP and c891w access point module to be forward to c891w router module? is it c891w access point configuration? or something to related to router module?

Thank you in advance.

Re: cisco 891w universal workgoup bridge mode

Hi

 

 Maybe this can help:

"Some third-party WGBs need to operate in non-DHCP relay mode. If problems occur with the DHCP
assignment on devices behind the non-Cisco WGB, use the config dhcp proxy disable and config dhcp
proxy disable bootp-broadcast disable commands.
The defaultstate is DHCPproxy enabled. The best combination depends on the third-party characteristics
and configuration. "

As I could see, you are not using WLC but this may apply to your environment with some adjustment. 

 

-If I helped you somehow, please, rate it as useful.-
