3com 4400与mrtg

cuiy

用3com 4400（四层）交换机连接几十台机器，用mrtg出图时，是否每一台机器都需要开启snmpd服务？
我用3com 自带 3com network supervisor可以察看其他机器的流量图，但是用mrtg时，总是提示：
[root@LOG-AWSTAT root]# /usr/local/mrtg/bin/cfgmaker --global "WorkDir: /usr/local/apache/htdocs/mrtg" --global "Options[_]: growright,bits" --ifref=ip  private@a.a.a.a  --output /etc/mrtg.cfg
--base: Get Device Info on private@a.a.a.a:

结果：不需要每一台机器开启snmpd，只需要交换机上配好了就好了
