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 Protocol switch: N/A Packet information: Passed packet(s) : 10766537 Dropped packet(s) : 0 Configuration information: Configured CIR : 448 kbps Actual CIR in NP : 448 kbps Configured CBS : 60000 bytes Actual CBS in NP : 60000 bytes Priority : The protocol has several CAR which have different priority.You can query the information by CAR Min-packet-length : NA CIR Configuration Type: Default History information: Last drop: Start time: - End time: - Last drop rate(pps): - Total dropped packet(s): - Peak rate: Time: 2018-11-13 17:04:28 Peak rate(pps): 1
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 ----------------------------------------------- BGP Packet Protocol switch :Close Packet information : Passed packet(s) :0 Dropped packet(s) :0 Peak drop rate : 1075395 pps 2014-07-08 19:49:47 Last drop rate : 1008235 pps 2014-07-08 19:51:47 Configuration information : Configured CIR: 512 kbps Actual CIR in NP: 100 kbps Configured CBS: 9000000 bytes Actual CBS in NP: 9000000 bytes Priority: BE Min-packet-length: 128 bytes
kullanılabilir.
