[mrtg] how to solve this problem: Could not match host

[tipaporn.p at psu.ac.th]

Hello,
   I used mrtg to monitor traffic from Huawei switch. In my cfgmaker
command, the option "--ifref=name" was used. As told in mrtg
documentation,This is the only sensible way to reference the interfaces
of the switches.  I found that sometimes mrtg will work and can pull
the data but sometimes it won't. The warning messages were shown as
below.
