Wayne,
Looks like it isn't supported on 2500s. Here is the supported platforms from
that link below.
Supported Platforms
.Cisco 2600 series
.Cisco 3640 routers
.Cisco 4500 series
.Cisco 7100 series
.Cisco 7200 series
.Cisco 7500 series with a Versatile Interface Processor (VIP)
Looks like you need at least a 2600 to do it. :(
Regards,
Eric

Subject: Re: Setting the DE bit in frame relay
I don't seem to be able enter the command 'set fr-de' without
specifying my policing parameters, could be I need to upgrade my
software. I running 2500's with System image
"flash:/c2500-is-l.122-15.T9.bin". Any recommendations other than
buying 2600/3600's
Cheers,
Wayne
