"cat6500-sup720 route-map"
Отправлено evb , 04-Май-07 11:12

Hепонятная ситуация с cat6500-sup720.
Обычно load cpu порядка 10-15%. Вешаем на интерфейс "vlan 2" route-map, в
котором указан next-hop для группы адресов - загрузка cpu резко возрастает до
~50%:
copter#sh proc cpu so | e 0.0
CPU utilization for five seconds: 52%/46%; one minute: 51%; five minutes: 50%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
122 5992932 52331490 114 4.87% 4.05% 4.11% 0 IP Input
Конфиг выглядит так:
interface Vlan2
ip address xx.xx.1.130 255.255.255.192
ip policy route-map PASSUS
ip ospf message-digest-key 1 md5 7 xxxxxxxxxxxxxx
ip ospf priority 10
end
route-map PASSUS permit 5
match ip address 91
set ip next-hop xx.xx.0.15
access-list 91 permit xx.xx.100.0 0.0.0.255
С этим можно как-то бороться?

а посмотрите sh ip int vl 2, sh int vl 2 switching, sh int vl 2 stats? может всё сразу ясно станет.

ip route-cache policy на интерфейсе,вроде как, должно решить проблему.
