Bence 4500'ler tek bir flow icin paketleri sira ile butun uplinklere yolluyorsa burada bir sorun var demektir. Aslinda cihazlar load-balancing isini paket bazli degil de flow bazli yapmali. Dolayisiyla bir bilgisayarin banka baglantisi (kac tane link olursa olsun) hep ayni uplink uzerinden gitmeli.

"show ip cef summary" gonderebilir misin 4500'lerden?

Bir de trace cektigin VLAN'in L3 interface'i icin "show ip interface XXX" ciktisini.

Selamlar
