Assuming you are able to query other MIB object values from your routers,
it is
most probably not a problem at the NetView end such as an incorrect community
string, but most likely that your routers do not support this RMON table. If
they do support RMON, you should turn it on at the routers. 

However, my guess is that it more likely that they support the EtherLike-MIB
than that they support RMON.  I would try a Get on dot3StatsFCSErrors in the
EtherLike-MIB. Load this MIB and try the Get. Loading the MIB will not turn on
anything at the routers but will mean you do not have to use the dotted
decimal
notation in your Gets. If you do not have this MIB file I can email it to you.

Check if the vendor documentation says anything about support of either the
Etherlike-MIB or RMON and if so, how you turn it on at the SNMP agent in the
routers. 

If neither works, you may still be able to find a CRC counter in one of the
vendor's enterprise MIBs. What routers are you using?
