However, one thing to consider is that CIR at any given point doesn't mean
that you have that end-to-end CIR.  Of course, without at least having the
port speed at your given CIR, you'll never go faster, but having the local
FR switch's CIR from 'show frame map' is useful.

Consider this:
PFI-LIV-3640#sh frame map
Serial3/0.20 (up): point-to-point dlci, dlci 20(0x14,0x440), broadcast, BW =
64096
          status defined, active
Serial3/0.22 (up): point-to-point dlci, dlci 22(0x16,0x460), broadcast, BW =
64000
          status defined, active
Serial3/0.19 (up): point-to-point dlci, dlci 19(0x13,0x430), broadcast, BW =
128000
          status defined, active
Serial3/0.18 (up): point-to-point dlci, dlci 18(0x12,0x420), broadcast, BW =
384000
          status defined, active
Serial3/0.17 (up): point-to-point dlci, dlci 17(0x11,0x410), broadcast, BW =
128000
          status defined, active
Serial3/0.23 (up): point-to-point dlci, dlci 23(0x17,0x470), broadcast, BW =
64000
          status defined, active
Serial3/0.21 (up): point-to-point dlci, dlci 21(0x15,0x450), broadcast, BW =
64096
          status defined, active

What's the total CIR for Serial3 into the cloud?  If you total it, it's
896K.  That's way over-provisioned as this customer only has 8 64K CIR (128K
BE) links, which means the max they can pump CIR from the endpoints is 512
CIR.  With Burst it's 1024, but since the far ends are guaranteed anything
beyond CIR, it's not really that worth while.

Of course, I'll have to call the FR carrier Monday and find out what is
really provisioned (always the best way, at least that way you're getting it
from the horse's mouth, even if they're lying).  The customer has no real
clue, as usual.

Also, some of the FR switches at the remote ends show BW statements, but
more than half (the more rural areas) do not, so it's only useful if you've
got a newer route that supports it.
