RouterOS Beginner Basics

Greeting..!
i have three ip address for three interfaces,
Eth-1:192.168.10,1/24
Eth-2:192.168.20.2/24
Eth-3:192.168.30.1/24
and each one have a DHCP in it and i want to see the devices that connected to Eth-1 only. when i open leases sub menu it give me all the devices on Eth-1 and Eth-2 and 3 so how can
i specify only interface-1 without the other..? anyone know..?

“Select a Specific DHCP Leases”???
=> “How to show leases of only one dhcp-server?”

You do not have specified if on WebFig or WinBox (i do not think you talk about termial), but is the same:
Use the filter button to display only the dhcp-server you want.

Rextended is half right. Yes, use the filter button, but you can’t select Interface (at least not on my RB4011 running 4.49.6), but you can select many fields including: “server”, “active server” or “address” and give it appropriate text to filter on.

i think you need to filter leases by server (dhcp server)

Selecting server will give all leases (active or not) on that server, “active server” will give only active assignments.

very thanksful for all replies here…! really appreciate the help..!

If you have IP set on the interface, you are doing it the old way (it still works)
New way is to use Bridge and VLAN

If you use MikroTik App for Splunk, you can se all DHCP request back in history using see picture. For more information see my signature.

Provided you are using a bridge at all.
In my case I use my router exclusively as a router, and all switch functions are done in switches.

Hey k666, you dont need to conserve vlans like you do water… :wink:
So the switches do all the dhcp then?

No, the main router (RB4011iGS+) does all DHCP, routing, and firewall functions.. But every physical interface of the router is a separate LAN or VLAN trunk. No LAN appears on more than one physical port of the router. Each router port is directly connected to one of two VLAN aware switches (CSS326-24G-2S). The switches do all the switching functions.

That I don’t. I just checked, there are 18 VLANs, 2 WANs, 2 trunk ports, & 6 untagged LANs in the 4011 router (SFP port not used currently). Yea, not exactly normal for a home user!

Now with all that said, I did manage (with massive help from here) to implement a simple (all one LAN) bridge on one of my old RB750 routers and a second RB750 with a trunk port and 4 untagged ports under a bridge as a stopgap when I was running out of switch ports in the data cabinet before adding the second CSS326. I fully admit that I have never understood bridging in ROS.
