Frame Relay DE to ATM CLP

jnaglich · ‎07-15-2008

I'm attempting to troubleshoot a problem from one of our frame-relay links back to an ATM DS3 at our data center. Does anyone know if there's a way that a Catalyst 7200 can track incoming packets that have been marked with a FECN or DE flag set? I saw that the DE bit can be mapped to the CLP flag in ATM, but in my router I only see the outbound CLP flags.

Does anyone know if this is possible?

Hi,

yes you can handle DE and FECN, but please explain the full topology and what you want to do with the bits.

Note, that could be a 7200 router (not a catalyst).
