Hallo,

I have a RB1100Hx2.
- on Eth1 is my uplink
- on Eth2 is our server
- Eth3-10 is configured as bridge, connecting all our local devices

In an earlyer post I have been told, that the software bridge is less efficient
then using the hardware switching capabilities of the RB1100Hx2.

Can I group Eth3-10 in one switch?
Or better to use a dedicated switch?

Howdy,

I believe ports 1-5 are in one switch group and 6-10 are in another. To use ports 3-10, you could configure ports 3-5 to one switch group, ports 6-10 in another, then bridge those master ports together.

But then a dedicated switch is probably better...after all the RB1100AHx2 is a router

Try something like this:

It works well for me, and you don't have to bridge as each switch group acts on its own (1-5) and (6-10)
