Hi,
First, thanks for the great work. JFFNMS is nice.
Second, following is a patch that will enable JFFNMS to work properly
with Dell Powerconnect Switches (at least tested with Powerconnect
3424).
No black magic here, the only problem with those switches is that
they always provide the same string ("Ethernet Interface") for the
MIB entries ifDescr. So, we simply detect if this is a Dell Switch
and indicate that the interface name is sored into the MIB entry ifName.
