This may be a dumb question, but I did search for my specific model of CPE. In short, we had an internet outage at a site today. Did all of the prerequisite checking (i.e. rebooted, removed FW, router, etc). Connected up a PC directly to CPE handoff (RAD ETX-203AX) and programmed one of our static addresses w/ correct subnet mask up to the CPE. Still no internet and what's worse is we can't ping the CPE public IP address (thus preventing from getting out to the internet).
Wireshark shows NO responses coming from the CPE, however, can see the VPN tunnel from the main branch side of things trying to initiate the session in Wireshark. Call Spectrum TAC, tech is great and they are trying to get access to the system remotely. CPE address CAN be pinged from outside of the network. After a few moments the CPE address starts pinging and internet traffic starts flowing. What's weird is that the MAC for the CPE is reporting an OUI of Cisco networks (not whatever RAD's MAC OUI space is). Spectrum noted that their management VLAN on the CPE is not responding so they cant get into the device.
My questions come from ignorance of the ISP world and really to try and figure out a root cause. So here goes.
- How do CPEs normally operate in a ISP handoff mode? Transparent bridge, VLAN isolation, etc...
- Could it be possible that this CPE is currently acting as just a fancy media converter for fiber to copper since the MAC reporting the public address for the CPE was a Cisco OUI?
