1.) What is the difference between applying a frame relay map-class under the
sub-interface as opposed to under the dlci?
R1(config-subif)#int s0/0.1
R1(config-subif)#frame interface
R1(config-subif)#frame interface-dlci 16
R1(config-fr-dlci)#class mclass-ypa
R1(config-fr-dlci)#
or
R1(config-subif)#int s0/0.1
R1(config-subif)#frame class
R1(config-subif)#frame class mclass-ypa
2.) When implementing cbwfq with service-policy on a link that carries both
critical applications, other hosting apps and internet traffic and within the
internet traffic limit ftp-data to a set rate. Frame -relay port speed is 512k
with a 384k cir
My thoughts were to use 3 classes for the hosting traffic. My concern is that
I'm not sure of the effect of the second service-policy within the
class-default to limit the rate of ftp-data, or whether using CAR on the S0/0
interface would be a better approach. Except it might limit all ftp including
traffic defined by other classes.
