Controllerless Networks

Hey so here is a quick layout of my set up. Firewall (Sonicwall NA 2600) that runs the DHCP server. Cisco POE switch. Then 6 IAP 215s in a virtual cluster. The problem we are having is, we have some different devices on our network that we connect to through different protocals. The main one is a synology nas rackserver that uses SMB. Over ethernet our internet clients can see the hostname and device show up in the Mac Finder sidebar or in Windows "Network" sidebar/tab. But over wifi through the aruba routers thoses devices don't show up. The weird part is I can still manually connect to the smb NAS with its hostname on windows or mac (so not a dns issue?), but they never show up in Mac/Windows Network Discovery area. For our emploeyes who aren't very tech savy this causes issues for them and slows down the work flow. I can't seem to solve it, so coming to the forum for help.

 

Thanks in advance! 

Are these devices all in the same VLAN? Do you have any Broadcast Filtering enabled on the SSID (Edit SSID -> WLAN Settings).

Hey thanks for the reply; yes the devices are on the same Vlan 1. We do have a guest network on Vlan 40 that uses 255.255.254.0, ip range 10.10.0.xxx - 10.10.1.xxx but we obvioulsy don't want internel devices access on that one haha (which they dont show up, so thats good). But our main wifi network is setup on vlan 1 subnet 255.255.255.0 ip range 192.168.1.xxx. Over wifi in network discovery there is always like 2 or 3 windows computers that will pop up but thats it(they dont have shares or anything). The NAS smb share just doesn't come up? With our older cisco wireless access points they were fine; these aruba routers are just really really nice and quick!

Might be worth checking to see if anything is being denied, the User Role which is assigned to the end user, does this restrict any traffic? You can determine this by running the following when trying to discover the shares.

 

#show datapath session | include [IP ADDRESS]

I got this:

(192.168.1.220 is the NAS ip)

f0:5c:19:c2:44:fc - Office# show datapath session | include 192.168.1.220

(192.168.1.102 is my ip on my laptop)

Here is a crazy part, it shows up under "Other Devices", but the SMB share doesn't.

Here is a link to a picture of my network tab in Windows 10. Also side note, only 1 "Computer" is showing up, over ethernet their would be 20+.

I am an idiot.. but I solved the problem. Broadcast filtering was enabled and I missed it. I disabled the filtering and now the NAS and all our computers are showing up correctly! Thank you!!

Hi ericarthurc

I have same issues with aruba (switch & AP).what are you doing to solve this issues.where was you disable filtering.

Hey their;

 

If you log into aruba instant and on the left side you should see the 'Networks' tab. Click on the SSID you want to brodcast devices on; click 'edit'. Then on the first page bottom click 'show advanced options'. On the left side you will see 'Broadcast/Multicast'; under it you will see the option 'Broadcast filtering'. I just disabled that option and then our NAS started showing up in File Explorer and Mac Finder over wifi.
