问题描述
怎样在交换机上通过命令来查看设备本身的mac地址，以及通过ip查询设备的mac地址的命令？
解决方案
查看设备本身的mac地址的命令
对于盒式设备，例如S2700/5700/S6700，可以通过查看二层接口的mac地址，也就是设备的MAC
如下，就是设备的mac地址：1047-8031-bbd0
[S5700]display interface
Eth-Trunk0 current state : DOWN
Line protocol current state : DOWN
Description:
Switch Port, Link-type : dot1q-tunnel,
PVID : 10, Hash arithmetic : According to SA-XOR-DA,The Maximum Frame Length is 1600
IP Sending Frames' Format is PKTFMT_ETHNT_2, Hardware address is 1047-8031-bbd0

如果是S9300的设备，可以通过命令 display system-mac 查看
display system-mac
MAC-num :1
Index MAC Addr
----------------------------
default 0025-9e03-1329
current d46a-b330-d341
如果需要通过ip地址查看下接设备的mac地址，dis arp命令加个参数就能看个某个接口下的全部ip和mac地址了，命令如下：
sys
Enter system view, return user view with Ctrl+Z.
[S_Buick]dis arp interface ethernet 0/0/36
