Nice new setup you've got there
Anyhow, I would use on the RB750GL Switch VLAN so you don't load the CPU and do the following steps:
1. Add a bridge for the VLAN
2. Add the ether1 port on the bridge
3. Create VLAN interfaces for the Layer3 routing that is running on the bridge
4. Set addresses for the VLANs
5. Set up DHCP server for the Client VLAN
6. Set up Switch VLAN
This can be done woth the following commands:
/interface bridge add name=bridge-VLAN
/interface bridge port add bridge=bridge-VLAN interface=ether1
/interface vlan
add interface=bridge-VLAN name=MGMT vlan-id=89
add interface=bridge-VLAN name=Client vlan-id=17
/ip address
add address=10.0.89.1/24 network=10.0.89.0 interface=MGMT
add address=10.0.17.1/24 network=10.0.17.0 interface=Client
/ip pool
add ranges=10.0.17.2-10.0.17.254 name=pool-clients
/ip dhcp-server network add address=10.0.17.0/24 dns-server=8.8.8.8,8.8.4.4 gateway=10.0.17.1
/ip dhcp-server add address-pool=pool-clients interface=Client name=dhcp-clients
/interface ethernet switch vlan
add independent-learning=yes ports=ether1,switch1-cpu switch=switch1 vlan-id=89
add independent-learning=yes ports=ether1,switch1-cpu switch=switch1 vlan-id=17
/interface ethernet switch port
set ether1 vlan-header-leave-as-is vlan-mode=secure
set switch1-cpu vlan-mode=secure
/interface ethernet switch rule
add dst-address=10.0.89.0/24 new-dst-ports="" port=ether1 switch=switch1
add dst-address=10.0.17.0/24 new-dst-ports="" port=ether1 switch=switch1
With the configuration of the HP switch I can't help you but with that of the Transmitter and Receiver I can. On the Transmitter you'll create a bridge, add ether1 and wlan1 (or whatever the name of the wireless interface is) to it, add a VLAN interface for the management running on the bridge, set it an address and configure Bridge VLAN because that's the only way for these devices. On the Receiver it's analogous. All of this can be done with the following config on the Transmitter:
/interface bridge add name=bridge-VLAN
/interface bridge port
add bridge=bridge-VLAN interface=ether1
add bridge=bridge-VLAN interface=wlan1
/interface vlan add interface=bridge-VLAN name=MGMT vlan-id=89
/ip address add address=10.0.89.2/24 network=10.0.89.0 interface=MGMT
/interface bridge vlan
add bridge=bridge-VLAN tagged=bridge-VLAN,ether1,wlan1 vlan-ids=89
add bridge=bridge-VLAN tagged=ether1,wlan1 vlan-ids=17
/interface bridge set bridge-VLAN vlan-filtering=yes
And on the Receiver (presuming the client will connect on ether2):
/interface bridge add name=bridge-VLAN
/interface bridge port
add bridge=bridge-VLAN interface=ether2 pvid=17
add bridge=bridge-VLAN interface=wlan1
/interface vlan add interface=bridge-VLAN name=MGMT vlan-id=89
/ip address add address=10.0.89.3/24 network=10.0.89.0 interface=MGMT
/interface bridge vlan
add bridge=bridge-VLAN tagged=bridge-VLAN,wlan1 vlan-ids=89
add bridge=bridge-VLAN tagged=wlan1 vlan-ids=17
/interface bridge set bridge-VLAN vlan-filtering=yes
