Hi,
anyone had done Cisco Press Lab 6 Section 7 on the QoS portion?
-----------------------------------------------------------------------
** Configure the frame Relay connecion between R2 and R3 such that the connection can adapt to congestion when a BECN is received from the network. Assume a 1544kbps access rate and a CIR of 64kbps.
the solution given was using
traffic-shape rate 1544000 38600 38600 1000
traffic-shape adaptive 64000
traffic-shape fecn-adapt
Can I use map-class frame-relay as the solution also? by the way, how the value 38600 come about?..:)
------------------------------------------------------------------------
** Consider VoIP to be a "critical" application. Configure PQ-CBWFQ (Priority Queueing-Class-Based Weight Fair Queueing) on R3 and R4 to guarantee a bandwidth of 256kbps on VoIP traffic and Fair-Queue with a queue size of 32 for all other traffic types.
the solution given is using
On R4
class-map match-all VOICE
match input-interface Serial0/0
!
policy-map Class1
class VOICE
priority 256
class class-default
fair-queue 32
!
interface Serial 0/1
service-policy output Class1
On R3
class-map match-all VOICE
match input-interface Serial0/0
!
policy-map Class1
class VOICE
priority 256
class class-default
fair-queue 32
!
interface Serial 0/0
service-policy output Class1
On R4, serial0/0 is shutdown. how it manage to classified the VoIP traffic by match input-interface Serial0/0?
anyone can advise?
many thanks
have a nice day
cheer!
Yong
