Anyone knows how to get the bandwidth data needed by the priority command to configure LLQ. with IOS 12.2.
I have a serial 256Kbps Link and wants, to apply QoS to the Voice only.
The only voice streams comes from a ata186.
Tanks in advance!!

your best bet is to use the QDM product which is a free download from cisco.
this configures llq as long as u know what setting u need to put in

Here is a sample config for LLQ for ip phone traffic this is based on a 128k circuit with 64k cir frame relay
------------access list to identify the traffic-------------
access-list 150 permit ip any any dscp ef
access-list 150 permit ip any any precedence critical
access-list 151 permit ip any any dscp af31
access-list 151 permit ip any any precedence flash
---------------Class maps and policy maps------------
class-map voip
match access-group 150
class-map cmcontrol
match access-group 151
!
!
policy-map voip-64k
class voip
priority 48
class cmcontrol
bandwidth percent 15
class class-default
fair-queue
---------------map class for FR DLCI---------------
map-class frame-relay FR-voip
no frame-relay adaptive-shaping
frame-relay cir 128000
frame-relay bc 1250
frame-relay be 0
frame-relay mincir 64000
service-policy output voip-64k
frame-relay fragment 160
this is onyl needed for Frame relay, if you have a point to point just apply the service-policy output command to the serial interface
--------------------interface commands-------------
interface Serial0
bandwidth 128
no ip address
encapsulation frame-relay IETF
service-module t1 timeslots 1-2
frame-relay traffic-shaping
frame-relay lmi-type ansi

interface Serial0.100 point-to-point
ip address 192.168.4.34 255.255.255.252
frame-relay interface-dlci 100 CISCO
class FR-voip
frame-relay ip rtp header-compression
