    Hi All Experts,

    Im confused by analyzing logging from my router regarding ppp
    negotations.
    I cannot find any useful guide how to read this loggings on cisco
    websites:

    1) debug ppp events

    RPM-13#
    Jul 17 09:13:53.957: ppp596 EVT: Packet 0 0x621F9BE4
    Jul 17 09:13:54.969: ppp596 EVT: Packet 0 0x621FB6C0
    Jul 17 09:13:55.381: ppp39 EVT: Free PPP 0 0x00000000
    Jul 17 09:13:55.977: ppp596 EVT: Packet 0 0x61B83140
    Jul 17 09:13:56.337: EVT: Dynamic Bind 0 0x623AC01C
    Jul 17 09:13:56.337: ppp701 EVT: Cstate 4 0x00000000
    Jul 17 09:13:56.437: ppp649 EVT: Free PPP 0 0x00000000
    Jul 17 09:13:56.437: ppp666 EVT: Free PPP 0 0x00000000
    Jul 17 09:13:56.989: ppp596 EVT: Packet 0 0x61B8402C


    How to bind this ppp interfaces, e.g. ppp596 with virtual-access
    interfaces which are cloned from virttual-templates? Any idea? What
    does Cstate mean? Do you know any cisco guide to this debug?


    2) Here are put some logs from "deb ppp neg"

    I have a lot different multilink interfaces, a lot of virtual
    templates from which virtual-access are cloned. But I see strange ppp
    interfeces (???) with even stranger numbers. How can I know which ppp
    interface belong to which virtual-access interface? Is there any data
    base within cisco router what maps it? What command I can use to see
    it?
    I realised that this ppp interfaces get random value each time virtual-
    access is cloned. No dependence.

    PS. My router is RPM in MGX 8850.
    UBS-RPM-13#sh ver
    Cisco Internetwork Operating System Software
    IOS (tm) RPM Software (RPM-JS-M), Version 12.2(15)MC2e,
    System image file is "c:rpm-js-mz.122-15.MC2e.bin"

    Thanks for any help,
    Aleksander.
