[c-nsp] underruns error locally && inputs errors, runts and abort on remote interface

[Ziad Majzoub]

Hello,
I'm seeing underruns errors on local STM1 interface,
on the remote router i'm seeing runts, aborts and imput errors
the controller is clean(during a certain period).

a policy map is created on the local router since there is lot of output
traffic
 Policy Map Shaper
    Class class-default
      Average Rate Traffic Shaping
      cir 137000000 (bps)


please advice!

no IP configured since there is sub interface with frame relay encapsulation
