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:
[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
cempMemPoolHCFree: 1.3.6.1.4.1.9.9.221.1.1.1.1.20 <<< memory free
For example:
1. Get the memory used.
