CRS210 switch, VLAN tagged switch DHCP-Client

RouterOS Beginner Basics
1

Hey MikroTik Gurus! I am wondering if you could help me finish setting up my CRS210-8G-2S+ switch.

I followed the MikroTik Wiki and got the basic VLANs set up and running (https://help.mikrotik.com/docs/pages/viewpage.action?pageId=103841836). Everything is working for the clients as expected.

I have eth1 as uplink to the router, and eth3-eth6 + eth8 as untagged with two different VLANs. Config below.
The uplink from the router is coming as untagged + tagged VLANs 5, 10 and 20. I am only using VLANs 10 and 20 for access ports.

Th thing which I do not know how to set up is the DHCP client on the bridge that will have the IP address assigned via VLAN 5. The way I have set it up now, the switch gets an IP assigned from the untagged VLAN.

CRS210 is, as far as I know, old switching chip and the VLAN assignments are done via the Switch menu, not the Bridge menu as per http://forum.mikrotik.com/t/using-routeros-to-vlan-your-network/126489/1 And even in that post, the IP is assigned manually and not via DHCP.

Is it possible to have the switch get IP address from the VLAN 5 subnet via DHCP?

Thanks!

You will have to add switch1-cpu to your tagged ports

/interface ethernet switch egress-vlan-tag
add tagged-ports=switch1-cpu vlan-id=5
/interface ethernet switch vlan
add ports=ether1,switch1-cpu vlan-id=5

Then, add vlan interface with ID=5 to the bridge
Add DHCP-CLIENT to the vlan and that should be good!

Hey, thanks a lot!
I managed to get it working already but a bit differently though. Can you please take a look and let me know if maybe your proposal is better?

/interface vlan
add interface=ether1 name=vlan5 vlan-id=5
/ip dhcp-client
add interface=vlan5
