Edi,
One way to set the DE bit for traffic exceeding 48K would be to apply a
policy-map like this:
policy-map POLICE
class class-default
police cir 48000 conform-action transmit exceed-action
set-fr-de-transmit
You can apply this policy outbound on a physical interface, subinterface, or
within a map-class frame-relay. On the far side enter "show frame pvc XXX"
where XXX is the DLCI, and you will see the counter for in DE pkts increase,
if traffic exceeds 48K.
HTH,
Bob Sinclair
