无用的信息太多了。

不想看到这些多链接信息可以调整一下snmpd的debug级别：

# echo "OPTIONS=\"-LS3d -Lf /dev/null -p /var/run/snmpd.pid\"" >> /etc/sysconfig/snmpd.options

或者直接改启动脚本

vi /etc/init.d/snmpd

找到这一项
OPTIONS="-Lsd -Lf /dev/null -p /var/run/snmpd.pid -a"

改为
OPTIONS="-LS3d -Lf /dev/null -p /var/run/snmpd.pid"

snmpd日志等级的定义:

0 或 ! —- LOG_EMERG
1 或 a —- LOG_ALERT
2 或 c —- LOG_CRIT
3 或 e —- LOG_ERR
4 或 w —- LOG_WARNING
5 或 n —- LOG_NOTICE
6 或 i —- LOG_INFO
7 或 d —- LOG_DEBUG

最后别忘了重启服务

# service snmpd restart
