追加信息

在实验室上检查端口范围。
  1. 开始 tcpdump收集日志。
    ::> network tcpdump start -node node-01 -port e0c
    Info: Started tcpdump packet trace on interface "e0c"
     
  2. traceroute ONTAP的默认设置开始、该设置具有64个跃点 、每个跃点具有 三个UDP发送
    ::> traceroute -node node-01 -destination 10.2.2.2
    traceroute to 10.2.2.2 (10.2.2.2), 64 hops max, 40 byte packets
    1  10.128.231.1 (10.128.231.1)  0.491 ms  0.316 ms  0.309 ms
    2  10.129.79.221 (10.129.79.221)  0.448 ms  0.670 ms  0.439 ms
    3  10.129.77.193 (10.129.77.193)  1.016 ms  1.357 ms
    10.129.77.194 (10.129.77.194)  0.857 ms
    4  10.133.128.106 (10.133.128.106)  121.045 ms  131.110 ms
    202.3.124.7 (202.3.124.7)  56.697 ms

    7  * * *
    ......snipped
    62  * * *
    63  * * *
    64  * * *
     
  3. 停止tcpdump日志收集。
    ::>  network tcpdump stop -node node-01  -port e0c
    Info: Stopped tcpdump packet trace on interface "e0c"
     
  4. 通过收集 tcpdumphttp(s)://<CLUSTER_MGMT_IP>/spi/<NODE_NAME>/etc/log/packet_traces/
     
  5. Verify the destination port range is from 33435~33626
