Hey there,
I just wondered when I use my Fluke cable tester it normally tells me which switch port I’m hooked up with… but not with my mikrotik switches (at least with ros on it)
Sometimes the main router is responding and telling me that’s where I’m connected to and sometimes i basically get no answer at all.
does anyone else have that problem?
best regards,
Do have LLDP/CDP active on your Mikrotik-Device ?
You can check under
/ip neighbor discovery-settings print
sry 4 later answer…
yes that is active
The Mikrotik Wiki is a bit hazy…
(https://help.mikrotik.com/docs/display/ROS/Neighbor+discovery)
I have a Fluke lying around at Work…
I will try and make some Test.
But maybe some other Forum-User has more experience with Mikrotik and CDP/LLDP
Hi,
so now I’ve just been to the situation where i would have needed it again, hence i had some time and run some tests with the switch.
the setup is as following:
Fluke Linksprinter 300
Internet → Mikrotik CCR1009-7G-1C-1S+ (router) → Mikrotik CRS309-1G-8S+ (main switch) → CRS354-48G-4S+2Q+ (client attached to it)
everywhere routeros installed since when we deployed the hardware switchos was not ready
the switches have the client vlan untagged on their ports.
CDP/LLDP/MNDP enabled (default value)
interface !dynamic (default value)
What happend while running some tests:
mostly the router is answering, sometimes i did not get any answer (switch section is simply empty), rarely the main switch (yep really) and the switch i’m attached to including the port.
We used to have a lot of aruba switches where the switch and the port was always there.
Do you have any ideas where that is coming from?
best regards.
The MikroTik Neighbor Discovery protocol may not be propagating correctly based on allowed interfaces. Especially so with VLAN. In In the Winbox GUI, go to IP / Neighbor List / Discovery Settings and observe.
Hi,
LLDP output from Procurve switches with CRS neighbours:

Note that the CRS112 reveal no port #. I suspect a Fluke would not be able to enumerate port # from such output.
@andkar, Thanks for the Feedback!
I did a Quick Test with a Fluke at work and a hap ac2
I wasn`t able to get Port-ID on both RouterOS 6.49.2 and 7.1
Hi Conny,
RB3011 with hap ac2 connected, only interface-name parameter:
interface-name=“bridgeLocal/ether1”
Interface number is present but maybe to imbedded in order to be detected by all devices.
