Cisco Mobility Express 8.5.151 - Wireless Clients Can't Access Wired Hosts on Same Subnet

hypnotoad — Mon, 05 Jul 2021 18:00:39 GMT

I have a single 3802i with CME 8.5.151. The wireless clients can ping their default gateway and any other wireless host. These same wireless clients cannot ping any non-wireless (aka wired) host on the same subnet. I've been looking through the configuration and nothing is obvious. What am I missing?

did you enable(drop) P2P blocking on specific WLAN.

I don't see peer-to-peer blocking as an option in 8.5.x. Isn't that in a later release? As I understand it, it is for wireless to wireless blocking. All of my wireless clients can reach any other wireless clients. I'm just having trouble reaching wired clients such as printers, servers, storage, etc.

Thanks,

There are three options:

Disabled—Disables peer-to-peer blocking and bridges traffic locally within the controller whenever possible. ...
Drop—Causes the controller to discard the packets.
Forward-UpStream—Causes the packets to be forwarded on the upstream VLAN.

you have to use CLI to configure it.

Can you try this comamnd and chekc again:

config wlan peer-blocking disable <wlan_id>

I just tried that command. Here are the results.

Request failed - WLAN 1 is already in the requested state.

Any more ideas?
