4.3. 执行网络内省以查看接口信息
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
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 | +-----------+-------------------+------------------------+-------------------+----------------+
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 +--------------------------------------+------------------------------------------------------------------------------------------------------------------------+ | Field | Value | +--------------------------------------+------------------------------------------------------------------------------------------------------------------------+ | interface | p2p1 | | mac | 00:0a:f7:79:93:18 | | node_ident | c89397b7-a326-41a0-907d-79f8b86c7cd9 | | switch_capabilities_enabled | [u'Bridge', u'Router'] | | switch_capabilities_support | [u'Bridge', u'Router'] | | switch_chassis_id | 64:64:9b:31:12:00 | | switch_port_autonegotiation_enabled | True | | switch_port_autonegotiation_support | True | | switch_port_description | ge-0/0/2.0 | | switch_port_id | 507 | | switch_port_link_aggregation_enabled | False | | switch_port_link_aggregation_id | 0 | | switch_port_link_aggregation_support | True | | switch_port_management_vlan_id | None | | switch_port_mau_type | Unknown | | switch_port_mtu | 1514 | | switch_port_physical_capabilities | [u'1000BASE-T fdx', u'100BASE-TX fdx', u'100BASE-TX hdx', u'10BASE-T fdx', u'10BASE-T hdx', u'Asym and Sym PAUSE fdx'] | | switch_port_protocol_vlan_enabled | None | | switch_port_protocol_vlan_ids | None | | switch_port_protocol_vlan_support | None | | switch_port_untagged_vlan_id | 101 | | switch_port_vlan_ids | [101] | | switch_port_vlans | [{u'name': u'RHOS13-PXE', u'id': 101}] | | switch_protocol_identities | None | | switch_system_name | rhos-compute-node-sw1 | +--------------------------------------+------------------------------------------------------------------------------------------------------------------------+
