It is CBWFQ if the map-class uses a service policy that is class based as in
the original thread, my question was 2 things.
1.) I understand that putting the map class on the interface applies to all
DLCI's and putting it under the Frame-relay interface-dlci applies it to
just that DLCI. But I was asking what if any is the difference in
configuring the frame class under a sub-interface as opposed to under the
interface dlci is?
2.) The goal is to us FRTS and configure a queueing mechanism and policer to
do the the following on a link carrying both critical traffic from a hosting
center to a customer as well as their less important and internet traffic
A.) Assign different queueing wieghts to different classes of traffic
from the hosting center to the customer across the FR link and guarentee a
minimum bandwidth to the two most important classes{p5-class and p3-class},
assign a higher precedence to other hosting traffic {p1-class}, Then use the
class-default for other traffic including internet.
B.) Rate-limit internet ftp-data.
Questions on this are what is the effect of the policy map configured to
police the ftp-data {class-d-policy}being used within the class-default of
the policy-map fr-out-policy. And would using a rate-limit on the serial
interface for ftp-data be a better way to go. although it might rate-limit
all FTP traffic including traffic matching other classes.
class-map match-all p3-class
match access-group name p3-acl
class-map match-all p1-class
match access-group name p1-acl
class-map match-all p5-class
match access-group name p5-acl
class-map match-all ftp-class
match access-group name ftp-data
