I prefer to have a trunk on the CAPS as well. Underneath the steps to change on the CAPS to have this configured.
Can you change the following on the CAPS:
/interface bridge
add admin-mac=04:F4:1C:xx:xx:xx auto-mac=no comment=defconf name=bridgeLocal \
pvid=88 vlan-filtering=yes
To:
/interface bridge
add admin-mac=04:F4:1C:xx:xx:xx auto-mac=no comment=defconf name=bridgeLocal \
vlan-filtering=yes
And change
/interface bridge port
add bridge=bridgeLocal comment=defconf frame-types=\
admit-only-untagged-and-priority-tagged interface=ether1 pvid=88
To:
/interface bridge port
add bridge=bridgeLocal comment=defconf frame-types=\
interface=ether1
And at last change
/interface bridge vlan
add bridge=bridgeLocal tagged=bridgeLocal untagged=ether1 vlan-ids=88
To:
/interface bridge vlan
add bridge=bridgeLocal tagged=bridgeLocal, ether1 vlan-ids=88
Make sure that ether2 on the TP Link is set to trunk as well!
