Guaranteed 256 kbps for Voice
Guaranteed 96 kbps for Class 1
Guaranteed 52 kbps for Class 2
To configure this QoS policy, enter the following QoS map and interface commands:
1. Allocate LLQ Priority voice traffic
ProCurve(config)#
qos map MyMap 1
ProCurve(config-qos-map)#
match list VOICE
ProCurve(config-qos-map)#
priority 256
2. Allocate the CBWFQ data traffic bandwidth for classes 1 and 2
ProCurve(config)#
qos map MyMap 2
ProCurve(config-qos-map)#
match list CLASS_1
ProCurve(config-qos-map)#
bandwidth 96
ProCurve(config)#
qos map MyMap 3
ProCurve(config-qos-map)#
match list CLASS_2
ProCurve(config-qos-map)#
bandwidth 52
3. Specify the reserved bandwidth and apply the map
ProCurve(config-fr 1)#
max-reserved-bandwidth 85
ProCurve(config-fr 1)#
qos-policy out MyMap
Technology Review
RFC791 created a single octet (labeled Type of Service) to help with the difficulty of trying to provide QoS
handling in IP networks.
According to RFC791, the Type of Service field contains the following bits:
The three-bit IP Precedence values (0 through 7) are specified as:
111
Network Control Packets
110
Internetwork Control Packets
