I'm putting together a 5-class QoS config for prioritizing Telepresence and VoIP to be configured on gig-ethernet interfaces in an ASR1001 WAN router. My question has to do with whether or not to use a bandwidth statement in the class class-default. From what I understand, class-default will use what ever bandwidth is remaining after the other classes. Is that correct?
The classes in the QoS config are as follows with two version of class-default:
Voice = 50mb
Telepresence = 50mb
Signaling = 5mb
Network control = 5mb
Class-default = remaining (or 800mb)
1. - without bandwidth statement in class-default
policy-map DataCenter_and_Triangle_Gigabit_5class
class Voice_Avaya
priority 50000
class Telepresence
priority 50000
class Signaling
bandwidth 5000
class Network
bandwidth 1000
class class-default
fair-queue
random-detect
2. - with bandwidth statement in class-default
policy-map DataCenter_and_Triangle_Gigabit_5class
class Voice_Avay
priority 50000
class Telepresence
priority 50000
class Signaling
bandwidth 5000
class Network
bandwidth 1000
class class-default
bandwidth 800000
fair-queue
random-detect
What would be the better way to configure class-default?
