Here is a portion of one of the configs. For some reason, whenever I
turn on FRTS my telnet sessions get *really* jumpy. Sometimes it almost
seems the router locks up but I think it's just my telnet session. If I
turn off FRTS on the main interface that jumpiness goes away.
In this particular case I haven't applied the VoIP class to all PVCs
and I'm wondering if that might cause a problem. We have two other
locations that we're testing VoIP with and they have a direct PVC
between them. VoIP calls between them sounds fine.
When we shutdown that PVC and then route the traffic through the
location whose config I'm including, the call quality is beyond horrid.
Demons gargling acid in Hell probably sound better than this. :-)
Any thoughts?
Thanks,
John

Can you send the config? I have been spending allot of time doing
traffic
shaping and may be able to lend some insight if I see the config.

I've had odd results implementing FRTS, as well. I've been told by a
Cisco engineer that it helps to reload the router after applying or
changing FRTS commands. I don't know if it's necessary but he said it
makes things work a little better. I haven't noticed a difference but
perhaps it's worth a try.

Hi All,
I implemeted the Traffic Shaping using map-class and assigned to
subinterfaces. The PVCs sharing that physical interfaces however
increase
in reply time and eventually timeout. What did I do wrong? When I
tried
General Traffic Shaping, it worked with "traffic-shape rate" and
"traffic-shape adaptive" commands. The reason I would like to
implement
Traffic Shaping with map-class because I would like to apply
"Frame-Relay
fragmentation" into some PVC to reduce delay time... Any idea why
Traffic
Shaping with map-class timeouts my PVCs? Thanks All!
Thomas N.
