setting up qos for wan

Unanswered Question
Dec 15th, 2007

Dear experts,

Is there any way to setup dynamic qos for dependant interfaces like atm+serial ?

unfortunatley it is not possible to configure CBWFQ because you can not bind the policy map with the "service policy" command to the interface , actually the interfae does not accept it .

I would realy do appreciate your assistance.

Best Regards,

Farshid

I have this problem too.

In such circumstances use either virtual templates or dialer interfaces, take a look at the PPPoA following example:-

interface ATM0/1/0

no ip address

no ip redirects

no ip unreachables

no ip proxy-arp

no atm ilmi-keepalive

dsl operating-mode auto

!

interface ATM0/1/0.1 point-to-point

no ip redirects

no ip unreachables

no ip proxy-arp

pvc 0/38

encapsulation aal5mux ppp dialer

dialer pool-member 1

!

interface Dialer1

bandwidth 1024

ip unnumbered Loopback0

encapsulation ppp

no ip redirects

no ip unreachables

no ip proxy-arp

tx-ring-limit 3

tx-queue-limit 3

dialer pool 1

dialer-group 1

service-policy output QoS-Policy

Another example using ATM interface:-

interface ATM0/1/0

bandwidth 1500

no ip address

no ip redirects

no ip unreachables

no ip proxy-arp

!

interface ATM0/1/0.1 point-to-point

no ip redirects

no ip unreachables

no ip proxy-arp

pvc x/y

tx-ring-limit 3

vbr-nrt 1500 1500

oam-pvc manage 3

oam retry 5 5 10

encapsulation aal5snap

service-policy output QoS-Policy

Example using Serial interface, in this example you have use a class, and within the class you specify the policy:-

interface Serial0/1/0:1

bandwidth 2048

no ip address

encapsulation frame-relay IETF

frame-relay lmi-type ansi

!

interface Serial0/1/0:1.10 point-to-point

ip unnumbered Loopback0

frame-relay interface-dlci 101 IETF

class QoS-Policy

!

map-class frame-relay QoS-Policy

frame-relay cir 2048000

frame-relay BC 20480

frame-relay BE 0

frame-relay mincir 2048000

no frame-relay adaptive-shaping

service-policy output QoS-Policy

Hope this helps

Regards

Allan.
