"Большая загрузка процессора Cisco 7206" Отправлено Luxor, 22-Апр-09 17:54
Здравствуйте, товарищи! Имеется Cisco 7206 NPE-G2, выполняет роль пограничного маршрутизатора на Интернет, также на нем работает NAT и BGP. На данный момент маршрутизирует порядка 140 Мегабит/с на входящий, и 50 Мегабит/с на исходящий и при этом загрузка процессора 85%/65% (65% по прерываниям). Помогите идеями :), цисковскую документацию по борьбе с перегрузками изучил но пока что глухо. Если эту тему увидят владельцы 7206 NPE-G2 отпишите пожалуйста сюда какой объем трафика она у вас маршрутизирует и какие сервисы при этом провайдит. Читал что у одного админа 7206 NPE-G2 500 Мегабит маршрутизировало и он был не доволен, а у меня только 140, представляете как недоволен я?!)) Приведу немного информации для анализа: rtr1-node10#sh interfaces switching GigabitEthernet0/1 IP-tunnel-to-VPN-server           Throttle count          0                    Drops         RP    7894874         SP          0              SPD Flushes       Fast   32893025        SSE          0              SPD Aggress       Fast          0             SPD Priority     Inputs    1750197      Drops          0     Protocol  IP           Switching path    Pkts In   Chars In   Pkts Out  Chars Out                  Process 2799492149 3193309513   69536565 1755240038             Cache misses          0          -          -          -                     Fast 2107472084 3093362577 2030008661 1149881674                Auton/SSE          0          0          0          0     Protocol  ARP           Switching path    Pkts In   Chars In   Pkts Out  Chars Out                  Process        884      53040       1110      66600             Cache misses          0          -          -          -                     Fast          0          0          0          0                Auton/SSE          0          0          0          0     Protocol  Other           Switching path    Pkts In   Chars In   Pkts Out  Chars Out                  Process          0          0     103183    6190980             Cache misses          0          -          -          -                     Fast          0          0          0          0                Auton/SSE          0          0          0          0     NOTE: all counts are cumulative and reset only after a reload.
