Rick, I'm running Frame Relay over an IP connection. There is no Frame
Relay switch in the middle. With the MINCIR setting still work if the
"Cloud" doesn't send back any BECNs?

Jim, try using just the CIR and MINCIR values in the map
class. Set the CIR to the frame port speed of 1.536, and the Mincir to
56kbps.

Subject: [nsp] Frame Relay question-CIR on a Cisco 2610
I am trying to set the CIR, Bc, and Be values on a Cisco 2610.
I would
like to set a low CIR and a high Be on a T1. When I set this on
a Cisco
2610 running 12.2.6 with frame-relay traffic shaping (CIR of
56K, Be of
1536000 on a 1.5 Mb link), things are hunky dory until I go past
the
CIR. As soon I hit the CIR, the Cisco will start to queue
packets in an
output buffer and latency goes to hell. There is no other
traffic on
this line. Why does the Cisco ignore my Be and queue the
packets? Why
does it take so long for a 2610 to service a queue? This
happens if I
am running FIFO or Fair queuing. Any help would be
appreciated.
Config snippets:
interface Serial0/0
no ip address
encapsulation frame-relay IETF
no ip mroute-cache
no keepalive
no fair-queue
frame-relay traffic-shaping
interface Serial0/0.100 point-to-point
ip address 10.1.1.1 255.255.255.252
frame-relay class test10
frame-relay interface-dlci 100
map-class frame-relay test10
no frame-relay adaptive-shaping
frame-relay cir 64000
frame-relay bc 600
frame-relay be 1536000
