写在最前面
#

对于 OID 着类查询，其实没有什么很好的方法，最主要的就是多 Google 一下，多尝试用工具 get 几个值看一下.请搜索 snmpwalk 这个小工具，windows 和 linux 版本都有.Linux 如何安装参考如下:

[root@localhost ~]# yum install net-snmp-utils

你可能需要的几个网址:

  • 查 OID 意思的网址

http://cric.grenoble.cnrs.fr/Administrateurs/Outils/MIBS/?oid=1.3.6.1.2.1.138.1.10.1.1

http://snmp.cloudapps.cisco.com/Support/SNMP/do/BrowseOID.do?local=en «< CISCO 官方的网址

  • 有关 cisco 产品所支持的 MIB 库.

ftp://ftp.cisco.com/pub/mibs/supportlists/

#show snmp mib object-name | inc <oid>  <<查看某个oid在9k上是否支持

接口相关的 OID
# 

ifAdminStatus 1.3.6.1.2.1.2.2.1.7  <<<<<  端口管理状态 up/down
ifOperStatus 1.3.6.1.2.1.2.2.1.8   <<<< 端口运行状态   up/down
MAC 1.3.6.1.2.1.2.2.1.6            <<<< 端口mac地址
ifInOctets 1.3.6.1.2.1.2.2.1.10    <<<<端口如方向流量字节总数
ifHCInOctets    <<<< 接口字节总数  64bit ， 建议使用这个 32bit 的有点问题
ifHCOutOctets
ifOutOctets 1.3.6.1.2.1.2.2.1.16   <<<<端口出方向字节总数
ifSpeed 1.3.6.1.2.1.2.2.1.5        <<<<端口带宽
ifDescr 1.3.6.1.2.1.2.2.1.2        <<<<端口名称
ifxAlias 1.3.6.1.2.1.31.1.1.1.18   <<<<端口别名/即端口description

Show interface 下的 last link flap 时间 # 

RP/0/RP0/CPU0:CORE6-ASR9922-A#show int hundredGigE 0/0/0/6 | in flapped
Tue Nov 27 21:07:00.288 UTC
  Last link flapped 01:07:40

We need following OID

1.3.6.1.2.1.2.2.1.2          ifDescr                              <<< get interface name and ifindex
1.3.6.1.2.1.2.2.1.9          ifLastChange                    <<< get the time of sysUpTime when interface state change
1.3.6.1.2.1.1.3.0              sysUpTimeInstance        <<< get sysUpTime

So Last link flapped time should be ( sysUpTimeInstance – ifLastChange )

For example:

[root@xuxing ~]# snmpwalk -v 2c -c cisco 10.75.49.13 1.3.6.1.2.1.2.2.1.2 | grep 0/0/0/6
IF-MIB::ifDescr.104 = STRING: HundredGigE0/0/0/6
[root@xuxing ~]# snmpwalk -v 2c -c cisco 10.75.49.13 1.3.6.1.2.1.2.2.1.9.104
IF-MIB::ifLastChange.104 = Timeticks: (9460) 0:01:34.60                                                           <<<
[root@xuxing ~]# snmpwalk -v 2c -c cisco 10.75.49.13 1.3.6.1.2.1.1.3.0
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (419819) 1:09:58.19                             <<<

1:09:58:19  - 0:01:34:60 = 1:08:24:00   same as above output

Show interface 下的 CRC 计数
# 

RP/0/RSP0/CPU0:ASR9006-F#                 show int tenGigE 1/0/0/1 | in CRC
Tue Dec 18 18:55:53.560 UTC
     559851 input errors, 55 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
RP/0/RSP0/CPU0:ASR9006-F#

we need following OID

1.3.6.1.2.1.2.2.1.2                  ifDescr
1.3.6.1.2.1.10.7.11.1.2          dot3HCStatsFCSErrors

[root@xuxing ~]# snmpwalk -v 2c -c cisco 10.75.49.35 1.3.6.1.2.1.2.2.1.2 | grep TenGigE1/0/0/1            <<< get ifindex and ifname
IF-MIB::ifDescr.375 = STRING: TenGigE1/0/0/1
[root@xuxing ~]# snmpwalk -v 2c -c cisco 10.75.49.35 1.3.6.1.2.1.10.7.11.1.2.375                               <<<get CRC counter

监控板卡的 memory 使用情况
# 

*if the LC memeory smaller than 4G,you can use below OID to check the memeory usage *
ciscoMemoryPoolUsed: 1.3.6.1.4.1.9.9.48.1.1.1.5
ciscoMemoryPoolFree: 1.3.6.1.4.1.9.9.48.1.1.1.6
*if the LC memeory bigger than 4G, use below OID*
cempMemPoolHCUsed: 1.3.6.1.4.1.9.9.221.1.1.1.1.18     <<< memory LC used

TIPs
# 

- 请添加SystemOwner的权限，要不然一些Fan speed之类的传感器的OID获得不到。
>snmp-server community cisco RW SystemOwner

- 请安装mgbl的PIE，要不然一些板卡，风扇的OID会获得不到。
