device connectivity via ap-bridge

Unanswered Question

Hi,


In one of our factory, there are handheld scanning devices which work over wireless to move data over to end servers.

The setup has two-5508 WLC in HA mode, about few 1500 series & 3500 series AP's.


handheld device is assigned an ip address & connected using copper cable to the ethernet port of 3502.

The 3502 here is functioning as a work bridge & connects to either other 3502/1500 which act as normal mesh AP's.


3502 shows connectivity to the wireless & back end infrastructure, however the handheld device can not be communicated from within our network.



Is there any special configuration required for this. Please help with suggestions.


Thanks in advance.

you may need to go and disable the IP mac binding


config network mac-ip-binding disable

Pls provide the below output from your WLC


(WLC) >show wgb summary

(WLC) >show  wgb detail



Other APs you mentioned are in MESH mode or LOCAL mode ?

Thanks Steve & Rasika.

I'll get these outputs from the local folks & present it here.


Another thing to note is , the scanner ip can be pinged from within the bridge itself, but it can't be from the local network infrastructure. All Ap's are in mesh mode. Below is the configuration from a bridge that is used for this purpose.

we tried adding static arp entry on to the bridge itself, it works for sometimes but then stops.

Hi


I suspect compatibility issue with mesh mode AP & WGB connection. I have not tested that & not sure whether it is working.


For testing is it possible to check your WGB with local mode AP & you should see the wired client in "show wgb detail" command as shown here
