PPPoE Session Status
(2021-12-03)
Problem
What is happening with my PPPoE session?
Solution
Nothing, probably, but here are some commands that will show you things:
# show vpdn session pppoe state
# show vpdn session pppoe packets
# show vpdn tunnel pppoe summary
# show vpdn pppinterface
...none of which will help you if there's something stupid wrong like the ISP side being locked to the MAC of the firewall you are replacing.
