Problem configuring Link Fragmentation & Interleaving

n.oneill
Level 1
Level 1

I have configured QoS on my ADSL router but the LFI doesn't appear to work. When I do a "show ppp multilink" it says there are no active bundles.

Relevant config as follows:

ip cef

class-map match-all cs

match access-group 120

!

!

policy-map qos

class cs

priority 128

class class-default

fair-queue

interface Virtual-Template1

mtu 1458

no ip address

ppp multilink

ppp multilink fragment-delay 10

ppp multilink interleave

!

interface ATM0

no ip address

no atm ilmi-keepalive

pvc 0/16 ilmi

!

bundle-enable

dsl operating-mode itu-dmt

!

interface ATM0.38 point-to-point

mtu 1458

pvc 0/38

encapsulation aal5mux ppp dialer

dialer pool-member 1

!

!

interface Dialer1

description "BT Openworld"

mtu 1458

bandwidth 512

ip address negotiated

ip access-group 111 in

no ip redirects

no ip proxy-arp

ip nat outside

ip inspect INBOUND in

encapsulation ppp

no ip mroute-cache

dialer pool 1

dialer idle-timeout 0

dialer-group 1

service-policy output qos

no cdp enable

ppp authentication chap callin

ppp chap hostname ************

ppp chap password 7 ***********

ppp multilink

ppp multilink fragment-delay 10

ppp multilink interleave

access-list 120 permit udp any host 195.20.108.10 eq 27050

Any packets matching access-list 120 are dropped unless I remove the ppp multilink statements

Any ideas?

On what interface are you trying to apply this on ? the AYM PVC or the dialer or both ?

As per the following article:

http://www.cisco.com/en/US/partner/products/sw/iosswrel/ps1834/products_feature_guide09186a00800804c1.html

WHich is apply it to the dialer and map the dialer to the physical interface.
