I'm probably doing something a bit stupid, but I have been banging my head against this for a week or so and still can't sort it out.
I have a home network with a CRS125 set up and working well with vlans 100, 200 and 300 just using the switch chip (just a L2 switch). I don't need to route through the CRS as it's hooked back to a Ubuntu server as a router with WAN connectivity and 3 further NIC's for each of the vlans. I'm also in the process of looking to replace the wireless points and so picked up a Hap lite AC to have a play with. The main internal vlan is 100, 200 is going to be a management vlan and 300 is guest. the only ones I'm playing with is 100 and 300 at the moment.
So I tried to use CAPsMAN with management forwarding and couldn't bridge the vlan 100 successfully onto the switch chip on the CRS (which is also using vlan 100). I gave up with the management forwarding and used local forwarding on the Hap and again if the switch chip is set up on the Hap (all on vlan 100), I can't bridge vlan 100 from the virtual AP onto the switch.
The only way I can get it working is with no switch chip running and bridging all of the local ports.
It seems like there is a limitation in that if I use vlan 100 on the switch chip then I can't bridge the same vlan id (100) from one of the virtual AP's on either the Hap or the CRS. Does that sound right?
All of the examples I have found using the switch chip and bridging at the same time seem to use a different vlan id for wireless.
Thanks in advance for your help.
