3.fcping
fcping类似于以太网的ping命令，可以使用fcping fcid检测交换机到指定端口的链路通信状态，并且可以得到链路延时信息。
示范：
MDS9222i-1# fcping fcid 0x7500ef vsan 1 count 4 -fcping执行4次，对象是0x7500ef，vsan 1
28 bytes from 0x7500ef time = 1283 usec
28 bytes from 0x7500ef time = 1256 usec
28 bytes from 0x7500ef time = 1256 usec
28 bytes from 0x7500ef time = 1243 usec
4 frames sent, 4 frames received, 0 timeouts
Round-trip min/avg/max = 1243/1259/1283 usec -最小延时1243u秒，平均延时1259u秒，最大延时1283u秒。
4.检查交换机状态
show environment [clock|power|fan|temperature]命令查看交换机clock、电源、风扇、温度传感器这些模块的运行状态。show environment后面可以接一个参数，用于查看指定模块的状态。
示范：
MDS9222i-1# show environment
Clock: -始终模块。每个交换机有两个，一个active，一个standby。两个状态都是正常。
----------------------------------------------------------
