追加信息

在实验中检查端口范围。

开始 tcpdump 收集日志。
::> network tcpdump start -node node-01 -port e0c

Info: Started tcpdump packet trace on interface "e0c"
从 traceroute ONTAP的默认设置开始，该设置有64个跃点 ，每个跃点有 三个UDP Sendings。
::> 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

停止 tcpdump 收集日志。
::> network tcpdump stop -node node-01 -port e0c

Info: Stopped tcpdump packet trace on interface "e0c"
tcpdump 通过收集 http(s)://<CLUSTER_MGMT_IP>/spi/<NODE_NAME>/etc/log/packet_traces/。
验证目标端口范围是否为 33435~33626。
