cAP after switch issue

Hello,

I am trying to configure a switch (CRS304) to work with a cAP-ax.

The switch is connected directly to a router (CCR2116). The router acts as the CAPsMAN controller.

Other cAP-ax units connected to it are working perfectly.

However, I must be missing something that is preventing the cAP-ax from functioning when connected via the switch.

CCR2116 ---> CRS304 ---> cAP-ax

The switch works without any issues with other devices connected to it.

VLANs:

111 - Main VLAN (used by all my MikroTik devices)

66 - MGMT VLAN

10 - Main WiFi

20 - IoT WiFi

30 - Guest WiFi

Below is the switch configuration:

model = CRS304-4XG

/interface bridge

add bridge=bridge tagged=bridge,ether1,ether2 vlan-ids=66
add bridge=bridge tagged=bridge,ether1,ether2,ether3 vlan-ids=111

And cAP config:

2026-11-01 21:36:30 by RouterOS 7.25

model = cAPGi-5HaxD2HaxD

/interface bridge
add name=bridge vlan-filtering=yes

/interface vlan
add interface=bridge name=vlan66_MGMT vlan-id=66
/interface wifi datapath

/interface wifi cap

no connection to CAPsMAN

set [ find default-name=wifi2 ] configuration.manager=capsman .mode=ap

/interface bridge port
add bridge=bridge interface=ether1
/interface bridge vlan
add bridge=bridge tagged=bridge,ether1 vlan-ids=10
add bridge=bridge tagged=ether1,bridge vlan-ids=20
add bridge=bridge tagged=ether1,bridge vlan-ids=30
add bridge=bridge tagged=bridge,ether1 vlan-ids=66
add bridge=bridge tagged=bridge,ether1 vlan-ids=111

I understand that VLAN 66 does not pass through to the cAP, but why?

First glance notes no /interface/brindge/vlan definition for 66 on the AP . . .
