    1) virus ihtimalini ortadan kaldirinin.
    2) Eger configurasyonda kullanmadiginiz seyler varsa silin.(ciktiyi
    yollarsan belki bazi tavsiyeler olabilir)

    Bunlardan sonra hala CPU cok ise demek ki 2511 sizin icin kuvvetli bir
    router degil.
    Eger BGP,OSPF gibi process varsa ve de uzun ACL, traffic shaping, frame
    relay compression vs varsa bunlar cok CPU kullanir..
    Mesela 2621 kagit uzerinde 10K paket process edebilir diyor. Ama benim
    2621 2 MB frame de bayilmaya basliyordu (99% CPU) trafigin yogun oldugu
    zamanda.
    Onu 2651XM ile degistirdim simdi 20% CPU'dan fazla gormuyorum..
    Sende 2511 den 26XX serisine atla..

    Subject: [cisco-ttl] 2511 yuksek CPU utilization ve 2 MB trafic

    Iyi gunler,
    Border router olarak kullandigimiz 2511'de zaman zaman yuksek
    CPU yasiyoruz. Ilk zamanlarda IP Input dan dolayi oldugunu
    anlamis ve ona gore bazi onlemler almistik. Fakat simdi CPU yuksek
    oldugunda "sh proc cpu" ile her hangi yuksek bir process goremiyoruz.
    Fakat cpu utilization cok yuksek oluyor, yogun saatlerimizde. Her hangi
    bir
    benchmark software'i ile trafigin karakteristigini olcebilirmiyiz? NetFlow
    enable, bunu kullanarak bir yargiya varabilir miyiz? Yogun saatdaki
    istatistik acisindan? Gerci ip cef enable durumdadir. IoS 12.1'i
    kullaniyoruz. 2 MBitlik bir trafigimiz var. Zaman zaman sature oluyoruz.
    Router upgrade dusunuyoruz.Mantiklimi? Su anki 2511 2MB trafik icin uygun
    mu? Hangi modele yukseltmemizi tavsiye edersiniz?
    iyi calismalar,
    -Mehmet
