Routing VLAN's over a LACP trunk port

I am very new to MikroTik, but I have used and configured HP & Cisco switches in the past. My HP 2810-24G switch died and I have purchased a Cloud Router Switch CRS125-24G-1S-RM. I have been playing with CRS125 switch for about a 5 days now and I can not seem to get it to work. I am trying to setup the switch do the following:

1 - Trunk 2 port using LACP (eth1 and eth2) - 10.16.10.0/24
2 - Add 4 Port Based VLAN’s - User - VLAN 20 -10.16.20.0/24 / Server VLAN 30 - 10.16.30.0/24 / VOiP VLAN 40 - 10.16.40.0/24 / Non-Trust VLAN 100 - 10.31.100.0/24
3 - All VLAN’s to router over the LACP trunk to my current Firewall. The Firewall handles (DNS, DHCP, NAT, etc)
4 - Add QOS to the Voice VLAN.

I have setup the LACP ports with little issue however, I am not sure how to setup the VLAN’s to tag and untag, so they router over the LACP trunk.

My questions are:
1 - Do I need a master port assigned, is so can the master port be the LACP trunk since all traffic will be entering and leaving? (What is a master port?)
2 - Where do I setup tag and untaged ports for the VLANs (What are EG VLAN Tag / IN VLAN Tag / EG VLAN Trans for?)

Please help, and thank you in advance . :smiley:

Hi,

CRS125 doesn’t have hardware support for LACP, you can set it up but all the traffic will go via switch’s CPU. Which is counterproductive as the CPU is rather weak.

No sure if this will work but you can try and use “Trunking”

Thank You I will give Trunking a try…
