问题描述
BMC上不显示以太网卡的连接视图，无交换机信息，包括交换机名称、交换机连接ID、交换机连接端口ID以及交换机端口VLAN ID。
环境信息
-
操作系统：[如 Ubuntu 24.04]
-
软件版本：[如 OpenUBMC2512]
-
硬件配置：[如 CPU、内存等]
重现步骤
-
登录BMC web
-
系统管理-系统信息-网络适配器-选中网络设备，选中以太网卡设备，点击端口属性下方隐藏标志
-
查看指定网卡的连接视图
期望结果
端口隐藏信息中有连接视图，显示交换机信息
实际结果
端口隐藏信息中无连接视图，不显示交换机信息
代码
1.网卡SP681支持MCTP和LLDP，且对应字段已经设置为true
2.交换机相关字段的配置

| PortIdSubtype | String | 只读 | 从网络交换机接收到的端口ID类型：1、Agentld；2、ChassisComp；3、IfAlias；4、IfName；5、LocalAssign；6、MacAddr；7、NetworkAddr；8、NotTransmitted；9、PortComp | L1: 基本类型信息 |

尝试过的解决方案
1.通过postman修改LLDPEnabled属性为true
2.查看日志
在设置LLDPEnabled属性为true后，依旧报Can’t find system description from LLDP
3.抓包LLDP报文
抓包LLDP报文成功，找到ChassisId、ChassisIdSubtype、PortId、PortIdSubtype、SystemName和System Description
没有ManagementVlanId，但是ManagementVlanId默认为0
4.追踪抓取通信报文
用tracemctp Endpoint_65_2 start抓取BMC 与 SP681 网卡之间，通过 MCTP 通道传输的 NCSI 管理报文
报文中没有lldp相关信息
% tracemctp Endpoint_65_2 start2.txt (435.3 KB)
确定Endpoint
BDF 地址
BDF=“0000:41:00.1”
把 BDF 映射到 phy_addr
MCTP 的物理地址（phy_addr）和 PCIe 的 BDF 有对应关系。0000:41:00.1 里的设备号是 0x41，换算成十进制就是 65。
在 MCTP 注册信息里找 phy_addr=65 的条目
idx:12, module_name = network_adapter, phy_addr = 65, msg_src_eid = 24, msg_type = 126, pid = 5611, process_tag = 3224632059 idx:13, module_name = network_adapter, phy_addr = 65, msg_src_eid = 24, msg_type = 1, pid = 5611, process_tag = 3224632059 idx:14, module_name = network_adapter, phy_addr = 65, msg_src_eid = 24, msg_type = 2, pid = 5611, process_tag = 3224632059
phy_addr = 65对应的 EID 是 24，而msg_type = 2正好是 NCSI over MCTP，也就是 LLDP 数据上报用的消息类型。
5.修改LLDPOverNCSIEnabled
platform.sr中LLDPOverNCSIEnabled为0，修改为1后，没有变化。
求助
1.app.log中bmc_core的Ildp_proc.c(338)一直报错：Can’t find system description from LLDP 是什么原因
2.LLDP报文中有相应字段，但无法解析和正确显示，如何解决
3.NetworkAdapter_1_01011B01的LLDPSupported=false，而且网卡资源中并没有LLDPSupported这个属性，是什么原因
4.LLDPSupported和SupportedLLDP字段有什么区别？
mdb_interface/json/intf/mdb/bmc/kepler/Systems/NetworkAdapter.json
5.LLDPSupported和vpd/vendor/Huawei/Server/Kunpeng/openUBMC/platform/platform.sr中的LLDPSupport又有什么区别
6.请问各位的BMC有没有正确显示交换机信息？可以发截图看一下吗？
