RB2011UiAS-IN using as switch

RouterOS General
1

Ciao, we have a problem for a simple setup with a router RB2011UiAS-IcN.

We need to use this model as a switch, electrically powered with 24V. It has a basic default configuration that includes the eth1 as wan, the eth2, eth3, eth4 and eth5 (Gigabit Ethernet) interfaces bridge ports and in that bridge the eth6, it is also the master of the others 10/100 interfaces eth7, eth8, eth9, eth10 the interfaces .

In our scenario we have a bridged network so we would like to use all interfaces of RB2011UiAS-IN like a switch, but we tried a single bridge with all the fast ethernets (6 to 10) and gigabit interfaces (1 to 5) but we had strong instability on the network (log print).

Do you have some advice?

thanks cetalfio

Ciao,
versione di RouterOS?
versione BIOS?
“/export compact” della routerboard?

devi metter in switch le ether1~etehr5 usando la ether1 come master,
poi in switch le ether6~etehr10 usando la ether6 come master
e in fine la ether1 e la ether6 in bridge

I think rextended already said it (I’m not that good in Italian) but what you did was actually ok.
Create a bridge with all ports.
Or create a bridge with one of the gbit ports and one of the 10/100 ports and set these as master for the remaining ports in the group.
If you are changing the default config keep this in mind:

  • IP 192.168.88.1 on the bridge
  • DHCP client is on ether1
  • DHCP server is running on the bridge
  • There is a NAT masquerade rule on ether1
  • Some generic firewall filter rules on input/forward chain

If you ARE changing the default config you might want to remove/disable the points above and put a usable IP address on the bridge.

It only want it work as switch.

Italian or not, read only the bold words… :smiley:

Thank you guys,
rextended procedure was the best solution for me, thanks rextended, but I still have a doubt, what’s the difference between these settings:
bridge1-1000
ports: ether1,ether2,ether3,ether4,ether5

bridge2-100
ports: ether6,ether7,ether8,ether9,ether10

bridge3-all
ports: bridge1-1000,bridge2-100

and

ether1-master-1000
ether2-slave-ethe1
ether3-slave-ethe1
ether4-slave-ethe1
ether5-slave-ethe1

ether6-master-100
ether7-slave-ethe6
ether8-slave-ethe6
ether9-slave-ethe6
ether10-slave-ethe6

bridge1
ports: ether1,ether6

P.S. rextended grazie simbolicamente un bicchiere di vermentino e due fettine di bottarga :wink:

Above, all traffic from any port to any other port crosses the router’s CPU. Throughput is limited to how fast the CPU can examine each packet and pick the destination port.

Traffic between Gigabit ports is switched at wire speed. The router’s CPU is not involved. Traffic between 10/100 ports is switched at wirespeed. The router’s CPU is not involved. Traffic from any Gigabit port to any 10/100 port is passed through the router’s CPU and throughput is limited by the CPU.

Exactly.

rextended explained it all. Only remark is that it is not possible to add a bridge as an interface to another bridge, so your first solution is not 100% correct. Nevertheless you get the point of bridging interfaces!
