某局点S6800与服务器互联端口lldp不显示system name

组网不涉及

S6800直连服务器

设备型号：S6800

不涉及

交换机和服务器互联的端口查看lldp邻居关系时只显示MAC地址不显示对端的system name

查看设备上lldp邻居不显示system name 

<LFRZ>dis lldp nei list 

Chassis ID : * -- -- Nearest nontpmr bridge neighbor 

 # -- -- Nearest customer bridge neighbor [19:46:26:670] Default -- -- Nearest bridge neighbor

 XGE1/0/1      ac1f-6b33-9de2        ac1f-6b33-9232           -

抓包确认对端服务器发过来的lldp博文是有携带system name字段过来的 

在交换机上debug和实际抓包对比来看，报文有差异，实际交换机上解析出的lldp报文并没有包含system 那么字段

最终确认是 服务器侧网卡自动发送LLDP导致，进而导致我司交换机没有学到操作系统发出的LLDP报文

可按照如下案例关闭网卡自动发送lldp
