问题描述
S5700-EI V200R003C00SPC300
S5700 配置NQA联动静态路由,测试把对端互联端口down,nqa已提示fail,但是联动的静态路由未消失
以下为大致配置:
ip route-static 11.80.17.30 255.255.255.255 Vlanif1 track nqa admin shuanghuo   
#
nqa test-instance admin shuanghuo
test-type icmp                          
 destination-address ipv4 11.80.17.242
source-address ipv4 11.80.17.240
frequency 2
timeout 1
start now
#
处理过程
1、根据故障现象怀疑NQA探测失败,命令查看nqa探测结果:
<ShengChanQu-HW5700A>  disp nqa results test-instance admin shuanghuo
 
 NQA entry(admin, shuanghuo) :testflag is active ,testtype is icmp
  1 . Test 32188 result   The test is finished
   Send operation times: 1              Receive response times: 1         
   Completion:no result                 RTD OverThresholds number: 0      
   Attempts number:1                    Drop operation number:0           
   Disconnect operation number:0        Operation timeout number:0        
   System busy operation number:0       Connection fail number:0          
   Operation sequence errors number:0   RTT Status errors number:0        
   Destination ip address:11.80.17.242                                  
   Min/Max/Average Completion Time: 4/4/4                               
   Sum/Square-Sum  Completion Time: 4/16                                
   Last Good Probe Time: 2016-11-22 13:37:58.6                          
   Lost packet ratio: 0 %                                 
以上信息可以看到探测no result,该提示为:测试正在运行,还没有得到结果。
但实际nqa已探测失败:
<HW5700A>display nqa history
 NQA entry(admin, shuanghuo) history:
Index T/H/P       Response Status       Address         Time                
 21   32188/1/1        4ms success      11.80.17.242    2016-11-22 13:37:58.620
经现网测试,icmp测试例现网配置frequency要配置大于等于10,才能计算出测试结果
frequency更改为10后,测试联动成功
        
    
根因

frequency测试间隔过短

解决方案
frequency更改为10
建议与总结
