CRS124-24G-1S Link Aggregation vs Bonding

Mikrotik Forum-

I have a question that I have not been able to figure out, and a problem that has been slowing me down. :laughing:

I have a CCR1036 and a CRS125 setup. From the CCR1036, I have 8 Ethernet going to my CRS125.

Right now, I am using bonding from CCR1036 to the CRS125 to achieve a higher aggregate speed between the two. I am seeing the throughput around 600Mbps, and the bottleneck is the CPU on the CRS125. I have read that using the switch chip with a trunk will improve that to near wire speed for each interface.

My setup on the CRS125 involves no VLANS. The CRS125 has 8 bonded ethernet ports that then serve DHCP / Internet to a bridge of local ports. As far as I am aware, this uses just the CPU, and doesn’t utilize the switch chip. I really need to find a way to do link aggregation of 8 ethernet ports and serve DHCP over the rest of the switch ports. I have referred to this example: http://wiki.mikrotik.com/wiki/Manual:CRS_examples#Trunking, but I have not been able to get it working. Can someone give me some help regarding this issue???

Any help on this matter would be greatly appreciated!

How far did you get, what did you try and what aspect of it is not working?

I have typed the following into my switch, but I don’t see anything happening:

/interface ethernet switch trunk
add name=trunk1 member-ports=ether2,ether3,ether4,ether5,ether6,ether7,ether8

I am not sure what I should set the master port to though, like it is referenced in the manual.

What should I do to accomplish a port trunk on my switch, and a ‘bond’ on my CCR1036? Also, how can I make the remaining ports on my switch use the port trunk as the communication link to my CCR1036, since the CCR1036 is serving DHCP, etc.

For example, my CCR1036 has an IP of 10.3.0.1/22. My CRS125 should have an address of 10.3.0.2/22. What interface do I assign that 10.3.0.2/22 address to? And how do I make a ‘bridge’ between the CCR1036 and the CRS125 using a port trunk / link aggregation? Can someone list the commands to do so, that was I can modify them and understand how this should work.
