hi
Does anyone have a sample configure or link that they could post to
run traffic shaping for voice and data packets over a single T1 with
ppp encapsulation.

thanks

Do you want traffic shaping or QoS?

I don't know for David, but I'd be interested in Priority Queueing over
PPP :-)

Configuring the PQ on PPP is the same as any other type connection here is a
config snippet. In this example any match, up to 30% of configured
bandwidth, on the class VOICE is assigned to the PQ. The policy-map is
applied to the serial interface. It dosen't matter if the serial interface
is using PPP encapsulation.


class-map match-all VOICE
match ip rtp 16384 16383
class-map match-all VOICE-SIGNALING
match access-group 103
!
!
policy-map VOICE-POLICY
class VOICE
priority percent 30
class VOICE-SIGNALING
bandwidth 16
class class-default
fair-queue

interface Serial5/0
ip address 192.168.80.13 255.255.255.252
service-policy output VOICE-POLICY
backup interface Dialer1
no ip route-cache cef
no ip route-cache
no ip mroute-cache

access-list 103 permit tcp any eq 1720 any
access-list 103 permit tcp any any eq 1720

Interesting... But that's bandwidth reservation, no ?

I'd like to do strict priotity queuing. For example, i have 2 ACL 101,
and 102

I'd like packets matching ACL 101 to be emited before ACL 102. Packet
matching ACL 102 would be emited only if there's no packet matching 101
in the queue. I can't see how I could do that with policy-map wich
reserve a percent of the bandwidth ???

It does because its the PQ. The priority queue is just that - priority. In
times of congestion when the interface doesn't have enough bandwidth to
transmit it queues traffic. When bandwidth becomes available it goes to the
queue and takes the packets that match the PQ first.

hi
thanks for your reply. So 30% of the bandwidth is for voice and voice
signaling has 16K. What about the other traffic do you need an
access-list for it too? Also i notice you disabled fast switching?.

thanks

Yes 30% of bandwidth is reserved for the PQ. You can create another class
map for the other traffic and set it for something other than priority (PQ).
Not sure how I haven't had to do that yet.

hi thanks for your reply. In the example 30% of the bandwidth is
reserved for voice. What happens if voice happens to exceed 30% of
the bandwidth. Is it dropped? or does it fall then under the default
class and gets delivered via fair queue
thanks

Yes, it does get dropped.

No.
