4.3. 执行网络内省以查看接口信息

download PDF

网络内省会从网络交换机获取链路层发现协议 (LLDP) 数据。以下命令可显示某个节点上所有接口的某个 LLDP 信息子集,或显示某个节点和接口的全部信息。这对故障排除非常有用。director 默认会启用 LLDP 数据收集。

流程

  1. 要获取节点上的接口列表,请运行以下命令:

    (undercloud) $ openstack baremetal introspection interface list [NODE UUID]

    例如:

    (undercloud) $ openstack baremetal introspection interface list c89397b7-a326-41a0-907d-79f8b86c7cd9
    +-----------+-------------------+------------------------+-------------------+----------------+
    | Interface | MAC Address       | Switch Port VLAN IDs   | Switch Chassis ID | Switch Port ID |
    +-----------+-------------------+------------------------+-------------------+----------------+
    | p2p2      | 00:0a:f7:79:93:19 | [103, 102, 18, 20, 42] | 64:64:9b:31:12:00 | 510            |
    | p2p1      | 00:0a:f7:79:93:18 | [101]                  | 64:64:9b:31:12:00 | 507            |
    | em1       | c8:1f:66:c7:e8:2f | [162]                  | 08:81:f4:a6:b3:80 | 515            |
    | em2       | c8:1f:66:c7:e8:30 | [182, 183]             | 08:81:f4:a6:b3:80 | 559            |
    +-----------+-------------------+------------------------+-------------------+----------------+
  2. 要查看接口数据和交换机端口信息,请运行以下命令:

    (undercloud) $ openstack baremetal introspection interface show [NODE UUID] [INTERFACE]

    例如:

    (undercloud) $ openstack baremetal introspection interface show c89397b7-a326-41a0-907d-79f8b86c7cd9 p2p1
    +--------------------------------------+------------------------------------------------------------------------------------------------------------------------+
