　　思科制造的路由器、交換機(jī)和其他設(shè)備承載了全球80%的互聯(lián)網(wǎng)通信，成為硅谷中新經(jīng)濟(jì)的傳奇，那么你知道cisco路由器flow調(diào)試指令嗎?下面是學(xué)習(xí)啦小編整理的一些關(guān)于cisco路由器flow調(diào)試指令的相關(guān)資料，供你參考。

　　cisco路由器flow調(diào)試指令：

　　Netflow 校驗(yàn)

　　show ip flow interface

　　show ip flow export

　　show ip cache flow

　　show ip cache verbose flow

　　clear ip flow stats

　　debug ip flow export

　　Show ip cache flow

Router# show ip cache flow

當(dāng)前cache下的 不同尺寸包所占的百分比

IP packet size distribution (12718M total packets):

1-32 64 96 128 160 192 224 256 288 320 352 384 416 448 480

.000 .554 .042 .017 .015 .009 .009 .009 .013 .030 .006 .007 .005 .004 .004

可見64字節(jié)的包占的比率非常大，將近55.4%

512 544 576 1024 1536 2048 2560 3072 3584 4096 4608

.003 .007 .139 .019 .098 .000 .000 .000 .000 .000 .000

顯然都是IP包，到1536為止了

IP Flow Switching Cache, 4456448 bytes （flow cache ,4.45M字節(jié)）

這個(gè)數(shù)是死的，即4M cache -size

65509 active, 27 inactive, 820628747 added 6萬(wàn)個(gè)活動(dòng)flow,27個(gè)非活動(dòng)的

　　show ip cache verbose flow

　　Show ip cache flow 與show ip cache verbose flow唯一的不同，就是active flow多了幾個(gè)域：

SrcIF SrcIPaddress DstIf DstIPaddress Pr TOS Flgs Pkts

　　clear ip flow stat-----------清除neflow cache，使show ip cache flow里的各項(xiàng)累計(jì)值清0
