This artical will recording some commonly used OIDs, like memory usege,interface counters.
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:
1
[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/

RP/0/RP0/CPU0:CORE6-ASR9922-A#show int hundredGigE 0/0/0/6 | in flapped2
Tue Nov 27 21:07:00.288 UTC3
Last link flapped 01:07:404
5
We need following OID6
7
1.3.6.1.2.1.2.2.1.2 ifDescr <<< get interface name and ifindex8
1.3.6.1.2.1.2.2.1.9 ifLastChange <<< get the time of sysUpTime when interface state change9
1.3.6.1.2.1.1.3.0 sysUpTimeInstance <<< get sysUpTime10
11
So Last link flapped time should be ( sysUpTimeInstance – ifLastChange )12
13
For example:14
15
