docker搭建ELK日志采集系统（五）
环境：
| 服务器 | 系统 | IP | 掩码 |
| elk | centos 7 | 10.99.101.232 | 255.255.255.0 |
| USG2210 | 防火墙 | 10.99.101.204 | 255.255.255.0 |
| S6720 | 交换机 | 10.77.0.2 | 255.255.255.0 |
五、华为交换机、USG日志上报logstash并输出到elasticsearch
USG、S6720与ELK已路由可达
过程如下：
华为交换机、USG info-center >> ELK 514/UDP >> ELK514UDP映射到logstash容器 51400 >> logstash input UDP51400 端口 > elasticsearch
交换机配置：
<S6720-30C-EI-24S-AC>dis current-configuration !Software Version V200R008C00SPC500 # sysname S6720-30C-EI-24S-AC # info-center loghost source Vlanif99 info-center loghost 10.99.101.232
