List,

I've got several GSR12008s running 12.0(31)S1 with minor to moderate 
input ignore errors.  On one in particular, it's got an Eng0 6xDS3 card 
with two DS3s to transit providers and an Eng2 4xOC12MM (two ports 
active) to the core routers.  The DS3s are showing heavy input errors, 
on the order of 1% on one of the DS3s and 0.01% on the other active DS3. 
  There's a simple ingress ACL on each DS3, no other ACLs anywhere on 
the box aside from a receive ACL.  The OC12 interfaces face an MPLS 
core, with MPLS TE to the last P and in a few cases to the egress PE. 
MDRR is in place.  Any suggestions on where to look?  I'm having a hard 
time imagining that a card built for 12xDS3 and de-populated for 6xDS3 
would run out of gas with 2xDS3, nor can I imagine there's any sort of 
egress backpressure from the OC12s.
