Process Switching and ‘debug ip packet’ command

Book: “Routing TCP/IP Vol. 1 SE” Section: Per Packet Load Sharing and Process Switching” Page 105.

 

“Note that the command debug ip packet allows only process switched packets to be observed. Fast switched packets are not displayed.”

 

In a previous thread I wrote under the CCIP discussion board regarding MPLS VPN. In a demonstration to one of my colleagues that customer-originated information was being imposed with a label on the ingress LSR and switched via LSRs, I flipped on debug ip packets on all routers in the MPLS cloud and pinged CE1 to CE2. As expected, debugging information started to appear on all LSRs in the LSP demonstrating that label switching was occurring. I was informed from MPLS Fundamentals book that IP CEF must be running for MPLS to work. How did I see debugging information if the statement made above is correct? (Yes- I know CEF is different than process or fast switching.)

 

Thanks

  1. Great way to debug FPGAs. Just drop one of these on your board, and use Python’s serial lib to command/control http://bit.ly/dohVLY

  2. and, very impoand: is your Bundle registered? :-) Otherwise, try to debug the Command class itself (helped me alot!)

    – Thomas Maul – With the debug log the dot at the end of the line tells you if the command/function completed.

  4. make sure u get the correct drivers n u turn on debug don’t think u gotta do the command prompt shit anymore ask tho

  6. actually ruby-debug is a command line front end for ruby-debug-base. Rubymine uses ruby-debug-ide front end.

    Sigh is not programmer friendly..too many button..where is the command line? I only understand build and debug button!
