1.检查交换机端口

Show interface [interface-range]

查看指定端口运行状态，WWN信息，配置参数，收发包统计信息。

示范:

MDS9222i-1# show interface fc1/1

fc1/1 is trunking – 端口fc1/1运行状态正常，是一个TE端口

Hardware is Fibre Channel, SFP is short wave laser w/o OFC (SN) –端口、SFP硬件信息

Port WWN is 20:01:00:05:73:ad:2a:00 – 交换机端口WWN

Peer port WWN is 20:01:00:05:73:ad:26:00 –对端WWN

Admin port mode is auto, trunk mode is on –端口模式配置是自适应，开启trunk

snmp link state traps are enabled – 启用snmp链路状态变更告警

Port mode is TE –端口运行模式是TE

Port vsan is 4 – 端口vsan号

Rate mode is dedicated –带宽模式是dedicated

Transmit B2B Credit is 250 –发送buffer是250

Receive B2B Credit is 250 –接受buffer是250

B2B State Change Number is 14 – b2b变更关联的SCR号是14

Receive data field Size is 2112 – 最大数据帧大小2112

Beacon is turned off – Beacon功能关闭

Belongs to port-channel 1 – 端口属于port-channel 1

Trunk vsans (admin allowed and active) (4) – trunk vsan是4

Trunk vsans (up) (4)

Trunk vsans (isolated) ()

Trunk vsans (initializing) ()

5 minutes input rate 0 bits/sec, 0 bytes/sec, 0 frames/sec – 5分钟收包统计信息

5 minutes output rate 0 bits/sec, 0 bytes/sec, 0 frames/sec - 5分钟发包统计信息

7468 frames input, 517940 bytes – 总体收包统计信息，没有报错。

0 discards, 0 errors

0 CRC, 0 unknown class

0 too long, 0 too short

9141 frames output, 380372 bytes –总体发包统计，存在丢包现象。

3210 discards, 0 errors

330 input OLS, 240 LRR, 36 NOS, 57 loop inits –Primitive帧统计信息

340 output OLS, 271 LRR, 156 NOS, 19 loop inits

250 receive B2B credit remaining –b2b buffer信息

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。

----------------------------------------------------------

Clock Model Hw Status

----------------------------------------------------------
