N7K设备型号：Nexus7000 C7010
N7K系统版本：System version: 6.1(2)
N2K设备型号：N2K-C2248TP-1GE
现在出现个问题，用笔记本接入N2K_01的35口，ping N2K_01上接入的存储设备管理口192.10.10.13时，存在丢包。
但笔记本接入N2K_02上ping N2K_02的存储设备管理口192.10.10.14时正常。
网络结构如下：
图中笔记本为每周巡检时，临时接入。
两台N7K_01与N7K_02已trunk模式互联，且做了端口聚合。
N7K上配有vlna 8-10,90,780,800，其中vlan 8-10，90起三层，并配有HSRP，以N7K_01为主，vlan 780、800使用二层。
两台N7K分别接有N2K
两台存储设备的管理口都做了双网卡绑定，并分别接入两台N2K。
存储设备A双网卡绑定：192.10.10.13/24
存储设备B双网卡绑定：192.10.10.14/24
两台N7K上相关配置：

排查过程：
1.怀疑N2K_01上端口问题，更换端口，还是丢包；
2.怀疑机柜的配线架端口或网线问题，更换所有跳线，更换存储机柜与N2K机柜中配线架端口，还是丢包；
3.用一根长网线，不走配线架，直接将存储管理口接入N2K_01，还是丢包；
4.怀疑存储设备本身端口有问题，用笔记本直连存储管理口，则不丢包；
5.在N7K_01上将vlan 800起三层，IP为192.10.10.10.1/24，在N7K_01上ping 192.10.10.13则不丢包；
6.怀疑N2K_01交换机有问题，更换存储机柜配线架端口，使原接入N2K_01的Eth 106/1/33链路接入到N2K_02的Eth 106/1/36口，则不丢包。
所以目前怀疑是不是N2K_01交换机出问题了，但该N2K_01上其他的业务端口均正常。
请教有什么方式可以检查N2K是否存在问题？

排查过程：
1.怀疑N2K_01上端口问题，更换端口，还是丢包；
2.怀疑机柜的配线架端口或网线问题，更换所有跳线，更换存储机柜与N2K机柜中配线架端口，还是丢包；
3.用一根长网线，不走配线架，直接将存储管理口接入N2K_01，还是丢包；
4.怀疑存储设备本身端口有问题，用笔记本直连存储管理口，则不丢包；
5.在N7K_01上将vlan 800起三层，IP为192.10.10.10.1/24，在N7K_01上ping 192.10.10.13则不丢包；
6.怀疑N2K_01交换机有问题，更换存储机柜配线架端口，使原接入N2K_01的Eth 106/1/33链路接入到N2K_02的Eth 106/1/36口，则不丢包。
所以目前怀疑是不是N2K_01交换机出问题了，但该N2K_01上其他的业务端口均正常。
请教有什么方式可以检查N2K是否存在问题？
