750UP only as switch

RouterOS Beginner Basics
1

Well, I want to configure 750UP only as switch, but when I’m trying to do something it’s not working as I expected.

So. I my network sheme is like that:

internet → wifi_router1 with DHCP [192.168.1.1] → switch1 → 750up [192.168.88.1] → wifi_router2 [192.168.1.251] → wifi_router3 [192.168.1.49] → switch2

To switch1 connected two PCs
and to switch2 connected another two PCs also.
I’m using three wi-fi routers because, there are long cables between them, and wifi area is expanding.

I think I dont need to change setting at ‘IP->Pool’ and ‘DHCP client’ at all, because I don’t want that 750up work like dchp-router,
I want it only split IP’s.

Sorry for bad English,
and soory if something that I’m asking is wrong, maybe I dont understand something in network configuration.

If you want use the routerboard as switch must you delete the default configuration.

Go to “system” “reset configuration” click on “no default configuration”. click on reset configuration

Than set routerboard to switch modus like the link here below.

Not in englisch but follow the print screens a made

but how I can connect to device after it reset without default configuration ?

4

With winbox click on the three dots you see the mac address from your routerboard.
Click on the mac adress and connect

5

nope, I tried it couple times, but list is always empty (before & after reset)

6

well it wa my brandmauer. It has ip 0.0.0.0 but connects by MAC. now trying to configure, thanks!

sadly, but on step 4, on ok click I get message Couldn't change Interface <ether2> - chosen master-port does not support this feature (6)

as I noticed from post http://forum.mikrotik.com/t/problem-with-untagged-traffic/59551/1

Ah you have one of those RB that wont do it on port 1…

Use port one for WAN only… Use port 2 and 3 for what your attempting and it will work.

That is a hardware limitation on a few boards.

but I connect 24V PoE cable with data in port 1.
What will be if I connect it to port 2 or 3?

If the routerboard is configured as switch can you use every port you want.

10

nope. tested it. 750UP won’t work from PoE from ports 2-5, it’s only working from port 1, but port 1 as I see is not a part of switch.
So, may be there is no another way to connect to networks in one single?

My first network works in 192.168.1.* space, and other from routerboard work in 192.168.88.*
I want to connect this two networks to single 192.168.1.*
I tried to set Ip>Pool & Ip>Addresses settings (changed 88 to 1), I tried to setup Ip>DHCP Relay also, but it all not works as I want.

Can you make a network layout (a plan) from your network please?

Since the ether1 interface is not part of the switch chip you have to create a bridge.
/interface bridge
add name=bridge-local mode=rstpEither put all ports in the bridge (1-5)
/interface bridge ports
add bridge=bridge-local interface=ether1
add bridge=bridge-local interface=ether2
add bridge=bridge-local interface=ether3
add bridge=bridge-local interface=ether4
add bridge=bridge-local interface=ether5or put only 1 and 2 and set 2 as master for 3-5
/interface bridge ports
add bridge=bridge-local interface=ether1
add bridge=bridge-local interface=ether2
/interface ethernet
set [find default-name=ether3] master-port=ether2
set [find default-name=ether4] master-port=ether2
set [find default-name=ether5] master-port=ether2

Wi-fi AP is only on 192.168.1.1
All over wi-fi routers works as repeaters

yeap, bridge do expected result! thank u very much!!
