      Selamlar tekrar,

      Sizin mail gelmeden once ccp yi ekleyecek yeri bulup gerekli tanimlari yapmishtim.

      Calsiyor simdi. Bir problem yok.

      Peki compress mppc ignore-pfc seklinde kullanmanin bana artisi eksisi ne olur?

      Bu AS yi kullanacak olan userlar buyuk oranda uncompressed, ozellikle text tabanli data alip gonderecekler.

      Ona gore bir performans ayari yapmaya calisiyorum da..

      Tesekkurler.

       

       

      Oguz.

      Merhaba

       

      Local olarak yapinca mppc calisiyor mu? ( yani TACACS kullanilmazsa ?)

       

      CCP TACACS tarafindan authorize olmamis gorunuyor.

       

    >>>>
      *Jan 1 23:14:30.510: TPLUS: received authorization response for 35: FAIL

      *Jan 1 23:14:30.514: As1/19 AAA/AUTHOR/FSM: We cannot start CCP
    >>>

       

      ACs de

       

      New service: ppp
      New protocol: ccp

       

      seklinde tanim yaptiniz mi?

       

    >>>>>>>>>>>
      To configure CCP /MPPC with NT Tacacs
      - ppp ccp in "interface configuration" "new services" in lower cases for user and group
      - if "user" is not seen, it needs to be selcted in "interface configuration" "advanced options" "
      Per-user TACACS+/RADIUS Attributes"
      - in the user profile and/or group profile

      You can also try with: compress mppc ignore-pfc
    >>>>>>>>>>>>>

       

       

       

      Calismazsa:
      daha detayli bir debug gerekecek
      deb isdn q931
      Debug ppp nego
      Debug ppp authen
      Debug ppp per-user
      deb ppp per-user
      Debug tacacs
      debug aaa authen
      debug aaa author

        Merhaba Oguzhan

         

        Soru 1:

        Mppc nin client tarafinda calismamasinin nedeni ne olabilir?

         

        Cevap 1:

        AAA kullaniyoruz, ve compression network authorization gerektirir.Burda sorun olabilir.

        Sorunu gormek icin asagidaki debuglari enable etmek gerekli

         

        deb isdn q931

        deb ppp neg

        deb ppp authen

        deb aaa author

        deb tacacs

         

        debuglari toplamadan once (msec formatta gormemiz icin)

        conf t

        service tim deb date msec

        service time log date msec

         

        bu sekilde nerde fail oldugunu rahatlikla gorururuz...

        (sh ver /sh run i her debugla birlikte tekrar gondermekte yarar var, ayni mailde olursa isimiz kolaylasir)

         

        Soru 2:

        Bir de, async connection icin idle time ayarini nereden yapabilirim?

         

        Cevap 2:

        Async-group u dialer interface olarak tanimladiktan sonra dialer idle-timeout komutunu kullanilabilir

        "dialer in-band" komutu gerekli.

         

        Not:

        Bu konfigle ISDN call sonlandiramazsiniz.

        interface Serial3/0:15

         no ip address

         encapsulation ppp

         dialer rotary-group 1 ==> Isdn call tum parametreleri dialer 1 dan alacak ama interface dialer 1 konfigi tamam degil, aklinizda olsun ( pool , ip address, authentication.....tanimlari eksik)

         

         

        Kolay gelsin

         

        Devrim

          AS5350 var elimde bir tane. Config ettim, guzel calisti hersey ancak bir sIkIntIm var.

           

          Ip header compression haricinde herhangi bir compression calistiramiyorum

           Compress mppc dedigimde ise,

          Username verificationdan sonra registering network kisminda yaklasik 10-15 saniye civarinda bekliyor client, daha sonra connect oldugunda dialup propertiesten baktigimda compression yapamadigini goruyorum.
