[j-nsp] PPP debug on Juniper

[Farid Rajaei]

Hi:

I am trying to analyze the PPP protocol message flow on my router, M10
junos5.7R1.2; I am using it in a lab against a protocol analyzer sending
IPv4 over PPP on both directions of 2 POS-OC3 ports I have. Is there any
way to see the exchanged messages and their direction, i.e. sort of
debug. I have already tried capturing frames on these two POS ports with
tcpdump then using Ethereal but source and destionation of PPP messages
are not being shown on Ethereal. The only thing I found was "show pfe
statistics traffic"  to see the ACK s I received on my Protocol
Analyzer.  Anyone has any idea to help me?


Thanks
Farid
