I am connecting to a 100Mbit WAN circuit, that is Burstable to 500Mbit. If I am going to use ASA traffic shaping on this, would I set the shape average to 100Mbit or 500Mbit? My main concern is protecting VOIP, while allowing file transfers access to the burst.
Here is what I have so far.
This is to match the Voice Traffic
class-map voice_traffic match dscp EF AF31
This is to priorities the voice
policy-map qos_class_policy class voice_traffic priority
And here is the shaping policy that will be applied to the outside interface.
policy-map qos_outside_policy class class-default shape average 100000000 service-policy qos_class_policy
And here it is applied to the external interface 'outside'
service-policy qos_outside_policy interface outside
Here are the options on the ASA to set the shape, and then set the burst commit.
mpf-policy-map-class mode commands/options: <64000-154400000> Target Bit Rate (bits per second), the value needs to be multiple of 8000 ASA(config-pmap-c)# shape average 10000000 ? mpf-policy-map-class mode commands/options: <2048-154400000> bits per interval, sustained. Needs to be multiple of 128. Recommend not to configure it, the algorithm will find out the best value
