huawei ağ ekipmanlarında cpu-depend ile paket analizi – 2

huawei ağ ekipmanlarında cpu-depend ile paket analizi yazısında temel olarak cpu-depend komutuna, kullanım amacına değinilmişti. bu yazıda ise daha özelleştirilmiş fonksiyonlarına göz atalım…

eğer bir slottakii servisleri ait bir incele yapmak istersek
