My setup consists of 2 x ZD-5000 (ver. 220.127.116.11 build 15) and about 430 x ZF7363 and about 10 x ZF7982.
When ZF7363 fails we replace them with ZF7982.
On average we have 2 - 5 WLANs per AP Group. For example AP100 might be setup with following:
WLAN A => SSID Guest => over Trunk => vlan 30
WLAN B => SSID VoIP => over Trunk => vlan 40
WLAN C => SSID Corp => over Trunk => vlan 50
We have Hotspot provider that operates on Guest vlan 30.
Now the issue. ZF7363 works just fine. DHCP kicks in as ip-helper is set on all trunk ports which face APs. Client devices connect to any broadcasted SSIDs, get IP and go online – no problem.
ZF7982 we are experiencing connectivity issues only on selected WLANs. For example,
client is able to get online via WLAN B (VoIP, vlan 40), and WLAN C (Corp, vlan
50). However, when connected to SSID Guest (vlan 30) we have no communication.
Client is associated with the AP – that I can see from ZD – but unable to
receive IP addr from DHCP. We tried assigning IP address manually to client but no change. It is like if vlan 30 is not added to the trunk group on eth port.
We are confused because ZF7982 which we use as replacement to ZF7363 are assigned to the same AP Group. All ports are set to a Trunk 1 - 4096. No L2 or L3 ACL are in place.
My question is why ZF7982 would be able to push traffic only over selected vlans where ZF7363 works just fine? Is this some bug? Anyone experience something similar?
