Clients in Guest VLAN can't ping each other

[OREric]

I'm having trouble setting up Guest VLANs on an HPE OfficeConnect 1950. I have configured two ports as hybrid ports with untagged VLAN 1 and 5, 1 being the default and 5 set up as the Guest VLAN.

They're authenticated via an external RADIUS-Server and when accepted they can both communicate with each other and the rest of the network as intended. When rejected, however, they don't seem to get into the same VLAN. Both receive an APIPA Address and cannot communicate with anything at all.

Any idea what might be causing this?

Not sure...but, probably, you forgot to define the (existing) VLAN id to be assigned to the unauthenticated Guests.

Something like aaa port-access authenticator unauth-vid x where x is the VLAN id you intend the unauthenticated guests will be member of.

I had already done that.
