巡检常见问题及解决方案（一）（巡检及处理问题记录）
1.端口下出现CRC错包统计
例如：
XGigabitEthernet0/0/1 current state : UP
Line protocol current state : UP
Description:
Switch Port, Link-type : access(negotiated),
PVID : 1, TPID : 8100(Hex), The Maximum Frame Length is 9012
IP Sending Frames' Format is PKTFMT_ETHNT_2, Hardware address is 4cf9-5d39-efa0
Current system time: 2017-12-08 14:10:22
Port Mode: COMMON FIBER, Transceiver: UNKNOWN_SFP
Speed : 10000, Loopback: NONE
Duplex: FULL, Negotiation: DISABLE
Mdi : -, Flow-control: DISABLE
Last 300 seconds input rate 1981032 bits/sec, 789 packets/sec
Last 300 seconds output rate 13763216 bits/sec, 1234 packets/sec
Input peak rate 3900736744 bits/sec, Record time: 2016-12-20 15:58:51
Output peak rate 1579418400 bits/sec, Record time: 2017-06-11 07:56:25
Input: 8074383226 packets, 3301841306523 bytes
Unicast: 8072437737, Multicast: 1008305
Broadcast: 1, Jumbo: 0
Discard: 0, Pause: 937183
Frames: 0
Total Error: 828399
CRC: 838399, Giants: 0
Runts: 0, DropEvents: 0
Alignments: 0, Symbols: 0
Ignoreds: 0
Output: 11492763448 packets, 15396671657189 bytes
Unicast: 11475385794, Multicast: 16770945
Broadcast: 606709, Jumbo: 0
Discard: 12, Pause: 0
Total Error: 0
Collisions: 0, Late Collisions: 0
Deferreds: 0
Input bandwidth utilization threshold : 80.00%
Output bandwidth utilization threshold: 80.00%
Input bandwidth utilization : 0.02%
Output bandwidth utilization : 0.14%
发现接口的Input方向存在CRC的错包则表示曾经或者现在存在上游发出的包里面存在错包现象
需要排查
解决方案：检查上游设备状态，是否存在丢包，光功率不正常等现象，
如果之前就出现了，但是存在数据没有清除需要观察包的数量是否增加，如果没有增加可以将接口下清除统计信息，避免不必要的报错，通过命令 reset count interface XG 0/0/1 清除接口下所有的数据统计信息。
2.查看光模块的参数信息，存在异常

Temperature(C) 34.527 80.000 70.000 0.000 -10.000 Normal
Supply Voltage(V) 3.307 3.630 3.465 3.135 2.970 Normal

Rx Power(avg dBm) -40.000 0.999 -1.000 -9.901 -11.897 Abnormal
=============|=================================================================
接受的光功率过低，可能为光纤没有接好，或者对端没有发光
3.电源显示不正常

1 PWR1 Present AC NotSupply 150.00
1 PWR2 Present AC Supply 150.00
2 PWR1 Present AC NotSupply 150.00
2 PWR2 Present AC Supply 150.00
AC为交流电源
DC为直流电源
可能原因：
客户就是单电源，并没有第二块电源模块
有第二块电源，但是没有加电
确实电源掉电
4.运行的配置文件与保存的配置文件不一致
display configuration changes
5.SNMP协议版本检查
SNMP version running in the system:
SNMPv2c SNMPv3
出现配置时同时兼容多个SNMP的版本，没有影响
6.根据现网中报的速率判断如果操作是否会影响业务
Last 300 seconds input rate 448792 bits/sec, 62 packets/sec
Last 300 seconds output rate 506664 bits/sec, 71 packets/sec
多采几次将input和output的包速率加起来判断是否有大量的业务运行
7.出现MAC地址飘移
display trapbuffer
#Feb 8 2017 18:37:18+08:00 C05_NAS_S5720_CSS L2IFPPI/4/MFLPVLANALARM:OID 1.3.6.1.4.1.2011.5.25.160.3.7 MAC move detected, VLANID = 3, MacAddress = 244c-0733-3205, Original-Port = Eth-Trunk100, Flapping port = XGE1/0/1. Please check the network accessed to flapping port.
可能原因：
客户端的移动---此时会在日志中出现简单的一条MAC飘移，没有影响
但是如果出现大量的MAC漂移日志，显示同一mac飘移，可能存在二层的环路，或者遭受攻击，检查stp的状态，MAC飘移表
------------------------------------------------------------------------------Move-Time VLAN MAC-Address Original-Port Move-Ports MoveNum-------------------------------------------------------------------------------S:2011-08-31 17:22:36 300 0000-0000-0007 Eth-Trunk1 Eth-Trunk2 81E:2011-08-31 17:22:44-------------------------------------------------------------------------------
可以通过配置MAC地址的同优先级不能覆盖，静态绑定，允许接入的最大MAC数量
8. 单板工作不正常

建议查看单板是否插紧或者更换单板，可能是没有插板卡
