3.fcping

fcping類似於以太網的ping命令，可以使用fcping fcid檢測交換機到指定端口的鏈路通信狀態，並且可以得到鏈路延時信息。

示範：

MDS9222i-1# fcping fcid 0x7500ef vsan 1 count 4 -fcping執行4次，對象是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 -最小延時1243u秒，平均延時1259u秒，最大延時1283u秒。

4.檢查交換機狀態

show environment [clock|power|fan|temperature]命令查看交換機clock、電源、風扇、溫度傳感器這些模塊的運行狀態。show environment後面可以接一個參數，用於查看指定模塊的狀態。

示範：

MDS9222i-1# show environment
Clock: -始終模塊。每個交換機有兩個，一個active，一個standby。兩個狀態都是正常。
----------------------------------------------------------
Clock Model Hw Status
----------------------------------------------------------
A 0.0 Ok/Active
B 0.0 Ok/Standby

Fan: -風扇模塊正常。一個三個風扇，一個交換機自帶，另外兩個有電源模塊提供，一個電源模塊自帶一個風扇。
------------------------------------------------------

5.查看交換機整體信息，包括微碼版本和配置信息，各個模塊的硬件參數和序列號，以及運行狀態。
