V5交换机dis dhcp-snooping可以看到DHCP的终端，V7交换机对应命令是什么

V5交换机，全局下，dis dhcp-snooping，可以看到终端获取的IP地址信息，

 DHCP Snooping is enabled.

The client binding table for all untrusted ports.

V7交换机，dis dhcp snooping ? 后面要带上参数，

 binding DHCP snooping entries 

 drni-statistics Display DRNI synchronization statistics for DHCP snooping entries 

 drni-status Display DRNI status information 

 information Configure the snooping information option 

 packet DHCP packets trust Display information about 

请教V7交换机，如果想像V5交换机那样看到终端获取到的IP，是不是需要在终端获取到IP之前在交换机上配置

# 

 dhcp enable

 # 

 dhcp snooping enable

# 

上联口接口下配置dhcp-snooping trust

下联口PC接口下增加如下配置

interface GigabitEthernet1/0/1 

 ip verify source ip-address mac-address 

 dhcp snooping binding record

# 

而后全局下查看的命令是，dis dhcp snooping binding
