Switch performance for RB2011

Thu Nov 07, 2013 4:15 am

For my customer network have totally 20 computer.
but there have some problem, usually LAN connection lost.

I use RB2011UAS (ether2,3) for 2 Network
ether2 10.1.2.1/24
ether3 10.1.2.1/24
ether1 WAN link

we found LAN on port 3 is connect with 4 switch (in chain)
[RB2011/ether3]------[SW1]------[SW2]-----[SW3]-----[SW4]
when a broadcast problem was showup. All of port on router board was disconnect in 1 sec.
after that computer in ether2 and ether3 can't connect to WAN(outside).
I think it should only ether3 was problem. ether2 and WAN must continue WORK.

I try to use L3 Switch (HP V1910) for solve in this case. It is no problem, it can separate problem and not effect in another VLAN(port).

It is a H/W performance or problem on RouterOS?

A broadcast storm could easily congest the RB2011 CPU, this may cause your problem. However the real question is, what causes a broadcast storm in your network?
