第 5 章 检查 OpenStack Networking 路由端口

OpenStack Networking 中的虚拟路由器使用端口来进行子网间的连接。您可以通过检查这些端口的状态来确定它们是否被正常连接。

5.1. 查看当前端口状态

以下过程会列出附加到特定路由器上的端口列表,然后演示了如何获得端口状态(DOWN 或 ACTIVE)的方法。

1. 查看附加到名为 r1 的路由器上的所有端口:

#  neutron router-port-list r1

结果输出:

+--------------------------------------+------+-------------------+--------------------------------------------------------------------------------------+
| id                                   | name | mac_address       | fixed_ips                                                                            |
+--------------------------------------+------+-------------------+--------------------------------------------------------------------------------------+
| b58d26f0-cc03-43c1-ab23-ccdb1018252a |      | fa:16:3e:94:a7:df | {"subnet_id": "a592fdba-babd-48e0-96e8-2dd9117614d3", "ip_address": "192.168.200.1"} |
| c45e998d-98a1-4b23-bb41-5d24797a12a4 |      | fa:16:3e:ee:6a:f7 | {"subnet_id": "43f8f625-c773-4f18-a691-fd4ebfb3be54", "ip_address": "172.24.4.225"}  |
+--------------------------------------+------+-------------------+--------------------------------------------------------------------------------------+

2. 使用端口的 ID(左面列中的值)运行以下命令来查看端口详情。命令运行结果包括端口的 status 值(在下面的例子中是 ACTIVE):

# neutron port-show b58d26f0-cc03-43c1-ab23-ccdb1018252a

结果输出:

+-----------------------+--------------------------------------------------------------------------------------+

+-----------------------+--------------------------------------------------------------------------------------+
