Hello,
i have a 1 MB link on a router which is divided as follows 256kbps for 4 voice calls, 500kbps for 1 video call, 256kbps for Data, from which i have to achieve the below.
Thanks

Hi
assuming you have marked your voice and Video traffic correctly, then have something like this for your policy, this assumes the WAN bandwidth is 1Mbps, you also need to allow some bandwidth for the voice control traffic
policy-map QOS_OUT_1MB
class RT-VOICE
priority percent 25
class RT-VIDEO
bandwidth percent 50
class CONTROL
bandwidth percent 3
class class-default
shape average 1000000 10000 10000
queue-limit 64 packets
random-detect dscp-based
random-detect dscp 0 32 64 10
then on the WAN interface add the following command
bandwidth 1000 < remember to set the bandwidth so the QOS percentages will work
service-policy output QOS_OUT_1MB
regards
Richard

Richard, just wondering. . .
Class class-default will get 22%? If pre-HQF, what about the default rule of being unable to allocate more than 75% to non class-default classes without changing maximum allocation? If HQF, without explicitly defining the 22%, you're sure that's what it will be?
Why are you shaping in class-default?
What's the reasoning behind the queue-limit, using WRED, and WRED's custom BE setting?

Joseph.
You are right of course, I just took part of one of my configs, I am not sure whether the bandwidth was 1 or 2 Mbps . The WRED bit was because we classify all our data traffic according to importance as well
was trying to give an idea of whats required.

Richard, gotcha, thanks.

What do you desire to happen for the 5th VoIP call if data is transmitting?
What router and IOS will you be using? (QoS features vary on platforms and IOS versions.)
What kind of video? Specifically real-time or streaming? Is the 500 Kbps an average or peak?
What codecs are you using for your VoIP and video? (As your allowing [?] 64 Kbps for each VoIP call, I just wanted to insure you're not using G.711 which requires more wire bandwidth then 64 Kbps - see http://www.cisco.com/c/en/us/support/docs/voice/voice-quality/7934-bwidth-consume.html)
Is the 1 Mbps link hand-off also physically that at the egress port?
