I have this on multiple netpower 16p units.
Bridge with all ports. Default configuration then VLAN filtering enabled. PVID on bridge is 1, frame types are admit all.
any port, lets say port 8.
bridge/ports, open port 8 and set PVID to 108 and leave frame types to admin all and leave ingress filtering unchecked.
bridge/vlans add 108 and set port8 to untagged and set port 1 ( the trunk ) to tagged.
If I plug an AP in on a bridged port w/o any VLAN settings and CPE connected to that, then I add a second link on port 8 to the same site and connect the two together (to provide a primary and failover link for instance) then the NP's STP will detect duplicate frames and block one of the ports.
looks like:
NP16 port 6 > AP > CPE > dumb switch
NP15 port 8 vlan 108 > ptp link > dumb switch
the logic here is that the ptp link is the primary (usually a 60Ghz) and I don't really want to run a dedicated 5Ghz backup link so I'm just linking to a sector. Plenty of downsides but it's a very rare situation that it's actually used.
So what's the fix here? Do I need to set all of the non-vlan ports to 'admit only untagged'? How do I prevent the VLAN 108 from leaking out the other ports and causing this loop?
thanks.
