Sertan,
IP adreslerini siz girmediniz mi switchlere ? Bence static ARP lari kaldirip tekrar her switchin ciktisini once kontrol edin, bir yanlislik olmasin diye.
Eger hersey dogru ise baglantilarda loop olup olmadigina bakin, yani o switchin gonderdigi trafik bir sekilde yine kendisine geliyor olmasi lazim baska bir porttan. Duz ve cross-over kablolari kontrol edin.

[cisco-ttl] Catalyst 2950 ip conflict problem

Arkadaslar merhaba,  

  5-6 tane Catalyst 2950 switch ve bunların Catalyst 3508 'e bağlandığı bir network var. Hepsi aynı vlan de (Vlan1) .  

  problemi yaratan 2950 nin sh ver çıktısı aşağıda:  

Cisco Internetwork Operating System Software IOS (tm) C2950 Software (C2950-I6Q4L2-M), Version 12.1(22)EA4, RELEASE SOFTWARE
(fc1)  

  Problem şu:  

  Bir sunucumuz var ve ip si 10.0.0.25 . Arada bir sunucu üzerindeki event log da ip çakışması var diye error alıyoruz.   Verdiği mac adresini incelediğimde problemli olan 2950 Switchin kendi mac- adresi olduğunu farkettim.  

  cisco2950G-253#sh mac-address-table | include xxxx.yyyy.zzzz  All xxxx.yyyy.zzzz STATIC CPU  

  Böyle bir saçmalıkla karşılaşan var mı ?  

  Not: ip adresi 10.0.0.25 olan sunucu için tüm switchlere statik arp ta girdik ancak bu hataları halen alıyoruz. NEden ne olabilir.  

  arp 10.0.0.25 aaaa.bbbb.cccc ARPA alias
