Hi,
I have a bridge configuration, VOO Modem + Mikrotik ac^2.
Is it possible to see the Mc Address of the VOO modem from the Mikrotik?
Thank you for your reply
It depends. If that’s a pure modem, i.e. your Mikrotik is getting a public IP, you may have some chance sniffing the traffic and finding some RFC1918 (aka “private”) IP addresses that may be the modem management interface. If the Voo device is also a wifi router and things, then you may have to log into it to check what is the MAC on the coax (“docsis”) side.
Anyway, the mac you likely want is probably on a sticker on the underside of the modem, it’s called either “CMAC” or “CM MAC”. Stands for “Cable Modem MAC”.
Edit: if you want to see the MAC from the ethernet side on your bridge:
/interface/bridge/host/print
Thanks for the feedback, sorry for the delay, I forgot to reply.
I'm with a Provider who uses Proximus lines.
My IP is obtained through a PPPOE session configured in the Mikrotik and at my ISP.
The Proximus modem is just bridged to have Internet Synchro.
When I do the command line, I get a Mac Address of the LAN3 port. My PC is plugged into this port.
MAC-ADDRESS ON-INTERFACE BRIDGE
0 DL 18:FD:74:68:4C:D3 ether3 bridge-LAN
1 DL 18:FD:74:68:4C:D6 bridge-LAN bridge-LAN
2 D E 20:1A:06:60:2C:A6 ether3 bridge-LAN
The aim was to see the Mac address without using the Proximus modem.
Thanks
Hmmm these are addresses on your local network.
If your Mikrotik is doing the PPPoE with your ISP, well I guess you have Internet access, and your modem is just bridging between the two, then it may be hard to get its MAC. Have you checked the underside of the modem? Also, if it is Proximus, I guess you’re not going over a coax cable, but over a telephony pair (xDSL)?
Out of curiosity, why do you need the modem’s MAC?
Sorry for the delay, I was abroad and then I forgot.
In fact, we have 1,000 xDSL and Docsis customers with pppoe sessions configured in a Mikrotik core and a specific vlan for each customer.
When a Mikrotik is plugged in, the MAC address of the modems pollutes the Mikrotik core logs.
I know how to block the MAC address from the logs, but I have to find the right one for the specific client, and I’m not going to go to every client.
Anyway, it’s not essential but I like learning new things. 
Thanksyou
