[mrtg] Any known Issues with propVirtual (53) interfaces and ifref=name

[Rusty Allen]

I getting lots of interesting behavior trying to collect data on 
aggregated ports
in some Cisco switches. The "ifName" table is not continuous and mrtg 
appears
to be getting lost. From the messages listed below "FEC-6/21-22" exist 
but at
"ifName.4220".

Are there any Know issues in this area?
