You can apply a frame-relay map class to only one dlci, and that is the best
way. And then based on the CIR
The 384k in lab 13 was for the http's 80% calculation (or 307kbps) which we
put in the earlier task. Notice they changed MINCIR there... very important
as that is used for bandwidth reservation, while CIR is used for
fragmentation/bc calculations.
Here is my answer...
map-class frame-relay DLCI_501
frame-relay cir 512000
frame-relay bc 5120
frame-relay mincir 384000
service-policy output httpreturn
frame-relay fragment 640
class-map match-all httpreturn
match access-group 115
!
policy-map httpreturn
class httpreturn
bandwidth percent 80
class class-default

interface Serial0/0

Subject: Frame-Relay Fragmentation Values - based on port speed or CIR?
Let's say you have a frame-relay circuit with multiple DLCI's on it.
The task states to configure fragmentation on only one of the DLCI's
without affecting the other DLCI's.
Would you configure the bc and fragment size based on the port speed
(access rate) or on the CIR of the specific DLCI?
This question comes from IE lab 13 Task 6.2 where it says the CIR for
DLCI 501 is 384k but in task 6.3 it changes CIR to 512k which is the
access rate and the fragmentation values are based off the access
rate.
Thanks,
Greg
