Hi,
I'm trying to locate a CPE but i have no idea which modem it's connected to. It's in a large appartment complex with almost a thousand users so i can't look at them one by one. I tried using the CPE MAC address in shows cable modem hosts but it dosen't seem to see the CPE behind the modems. We're using a Motorola BSR2000 . Can someone help me with the command i'm supposed to use to scan the entire network looking for a specific CPE MAC ? Is that even possible with the equipment we have there ?
Thanks!
Try show cable host authorization | include MAC
Hi,
What you should use is option 82. I don't know how it is configured with BSR but on Cisco is:
ip dhcp relay information option
This way you can search the dhcpd.leases file and under the mac of CPE also relay-agent (modem MAC) will be displayed.
It is far the easiest way doing it and it is supported by default with isc-dhcp.
