我们单位接入的是10M光纤,内部大概有差不多1000个用户,网络结构是电信进来接cisco3845路由器,再接cisco pix525防火墙(做内网的NAT和服务器的DMZ),再接cisco 4507交换机做核心,下接cisco2590做接入,内网用户划分了3个vlan,现在感觉网络特别慢.延时都在200多ms,而且丢包也很严重,有10%左右.查看了一下路由器的接口情况,如下:
GigabitEthernet0/0 is up, line protocol is up(内网口)
Hardware is BCM1125 Internal MAC, address is 0015.2bd6.f3c0 (bia 0015.2bd6.f3c

其中内口reliability 255/255, txload 1/255, rxload 2/255
而外网口reliability 255/255, txload 248/255, rxload 92/255
这是怎么回事?
大家帮忙分析一下.除了这个还会有什么问题吗? |
