HI,
I am having a WAN connection between 2 sites A&B. ON A side we are using a private/leased line of 768k and on B side we are using 12 channels of a PRI line.
When I am applying QOS on the A side eveything is fine and in the the output of command "sh int s0/0" it is showing available bandwidth is equal to 75% of 768K.
But on B side when i have applied Qos it is showing me the available bandwidth is 3kb.
After removing QOS on the channel-group int it is showing me 768k of avaible bandwidth in "sh int s1/0:1".
I have attached all the outputs in the attachment.
Waiting for the replies.
Regards
Mahi

Hi Mahi,
The attached policy is
policy-map mahi
class QPM_Q6
bandwidth percent 4
random-detect
class QPM_Q5_1
priority 230
class QPM_Q3
bandwidth percent 35
random-detect
class QPM_Q1
bandwidth percent 1
random-detect
class class-default
bandwidth percent 30
random-detect
The formula to consider is:
Available Bandwidth = max-reserv x interface bandwidth - allocated bandwidth
In your case:
interface bandwidth = 768 kb
max-reserv = 100%
allocated bandwidth = 230 kbps + 30 kbps (4%) + 268 kbps (35%) + 7 kb (1%) + 230 kbps (30%) = 765 kbps
Thus remaining bandwidth is 3 kbps. Nothing wrong with it. Router can do the math.

Hi Martin,
We are using same kind of QOS policy on other channel group interfcae also. ALL interfaces are configured with "max-reserved bandwidth command" as well as 100% distribution of bandwidth in QOS classes but they are showing half of the bandwidth as avaible bandwidth.
Can you clarify my doubt.
Thanks for ur reply.

Hi Mahi,
Can you provide the configs and respective show command output? Without this it is hard to state anything.
