WLAN configuration - enabling inter-VLAN L3 isolation in AC

Latest reply: Jan 11, 2021 12:14:15 374 6 2 0 0

Dear Sir,


I set up and WLAN environment with 3 SSIDs mappings to 3 VLANs respectively to AC using direct forwarding mode


In the AC, I configure 3 Vlanif that corresponding to the 3 SSIDs, where the traffic from 3 VLANs will forward to outside (i.e. internal or internal network) via a router.


To avoid the 3 VLANs communicating with each other, I would like to configure inter-VLAN isolation such that the 3 VLANs cannot communicate with each other, but only forward to outside via a router.


can you advise how to configure inter-VLAN L3 isolation?

Hi ricyeunghk2003,
You can configure ACL-based simplified traffic policies to implement Layer 3 isolation between VLANs.
You can refer to https://support.huawei.com/hedex/hdx.do?docid=EDOC1100169994&id=EN-US_TASK_0180757211&lang=en
I hope it helps!

The example above didn't apply to my case as I assigned 3 SSIDs but I find that the 3 VLANs can communicate with each other.

I find a document https://support.huawei.com/enterprise/en/doc/EDOC1000141933/84cf570f/example-for-configuring-a-traffic-policy-to-implement-inter-vlan-layer-3-isolation

but i follow the same configuration to work out but the STAs in each SSIDs can ping with each other.

i don't know why
