How to autodiscover mikrotik

How I can autodiscover mikrotik in my lan? It’s an UPD? witch format?
I want to develope a little application by my self, like NeighborViewer, that retrieve informations about all mikrotik in the lan.

ok…but if I want to develope a personal application?

normis · April 18, 2006, 12:59pm

you can use ping, snmpwalk and other tools to discover devices and services

procad · April 18, 2006, 1:08pm

but how can I be shure about to find mikrotik?

OK, let me pick that up.

I can see roughly what’s happening when you press the “…” button in the WinBox connection dialog (broadcasts, …) using a packet sniffer.

Would MikroTik open up the details of the possible responses of RouterOS devices?

Yes, something like that.

MT uses CDP (Cisco Discovery Protocol), described in full at http://www.cisco.com/univercd/cc/td/doc/product/lan/trsrb/cisnm.htm

Banging … my … head … on … the … wall …

Thanks! Of course - that was to expect, as I can see our Ciscos with it

BUT…
using CDP Monitor software we cannot scan MT.

IP->Neighbours, and enable the discovery interfaces.

They are enables. Simultaneously checking with Neighbor viewer shows MT. But with any other CDP MONITOR software MT is not discovered. I think MT is not 100% CDP.

Works fine for me,

That’s a CDP client on Unix picking up my mikrotik box. You don’t perhaps have some firewalls somewhere dropping the packets?

I am using CDP Monitor from TALLSOFT. It works on WINDOWS XP. It doesn’t show. Do you know any software which works on Windows and can scan MT. I don’t want to use Neighbor Viewer for some reason.

savage · April 20, 2006, 11:27am

Windows? unfortunately not.

Keep in mind, it is very possible that the firewall in SP2 may block this traffic…
