Configure vlans to use bridge

RouterOS General
1

Hello forum,

I am chasing down a performance issue I am facing when running an iperf test from a client connected to a CRS305-1G-4S+ switch at 10G to a server across the internet. I see speeds of 16-20 MBytes per second. Going to a 1GB connection to my Netgear JGS516PE, I see speeds of 40-50 MBytes per second.

The CRS305-1G-4S+ 10G switch connects using the eth/mgmt port as an uplink to my Netgear JGS516PE. One port from the Netgear switch acting as a trunk port connects to ether3 on my RB4011iGS+.

How can I configure a bridge and connect ports ether3 and sfp-sfpplus1 on the RB4011iGS+ so that both ports on the router are trunk ports? Second, how can I configure vlan’s on CRS305-1G-4S+? Do I need to be in RouterOS mode for that? Or should I explore getting an sfp ethernet adapter and use an available sfp port instead of the eth/mgmt port on CRS305-1G-4S+.

Ether1 on CRS305 is mgmt port and should be used only for that purpose only !!!

Look at the block diagram: https://i.mt.lv/cdn/product_files/CRS305-1G-4S_220955.png

I would advise you to use Router OS for configuration.

Not really. It’s a regular 1G port. You can use it for what you want.
Look at the block diagram, indeed :laughing:

Yea, indeed… It was too early… But still, use Router OS, you will have much more information on what is happening.

Can’t argue there.
