Hi
I am trying to come up with a config for implementing QoS over a 512 kbps WAN link that will traverse voice and data traffic for now.
i am using a cisco 2901 router with 15.1(3)T IOS on it
my config is below
class-map match-any DATA-PRIORITY
match protocol citrix
match protocol ssh
class-map match-any VOICE-CONTROL
match protocol skinny
match protocol mgcp
match protocol h323
class-map match-any VOICE
match protocol rtp audio
class-map match-any ANY
match any
policy-map QOS-POLICY
class VOICE
priority 188
set dscp ef
class VOICE-CONTROL
bandwidth 32
set dscp af31
class DATA-PRIORITY
bandwidth 180
random-detect dscp-based
set dscp af21
class ANY
shape average 500000
class class-default
fair-queue
random-detect dscp-based
set dscp default
policy-map WAN-QOS-POLICY
class ANY
shape average 500000
service-policy QOS-POLICY
interface GigabitEthernet0/1
bandwidth 512
ip address x.x.x.x x.x.x.x
ip pim sparse-dense-mode
service-policy output WAN-QOS-POLICY
THE ISSUE IS :
when i add in the service-policy output WAN-QOS-POLICY command , i get the error " insufficient bandwidth 256kbps for bandwith guarantee (180)"
if i take out the " bandwidth 512 " command out then i get no issues adding the above command on inteface g0/1
Any help will be great.
thank you
