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

şüphelendiğimiz protokolleri/servisleri daha yakından incelemek istersek, arp için

[fc-route]display cpu-defend car protocol arp statistics             
 Slot               : 3
 Application switch : Close
 Default Action     : Drop
--------------------------------------------
 IPV4 ARP packet

slot 1 deki bgp protokü için ise

[fc-route] display cpu-defend car protocol bgp statistics slot 1
Slot                       :1
Application switch         :Open
Default Action             :Min-to-cp
