VLAN based QoS on a HPE comware Switch

Good afternoon my fellows!

There are many ways to configure quality of service (QoS) on a switch. First we need to classify what we want to be on a higher priority. You can classify an access-list, vendor-mac-addresses or just everything/any. In my case I wanted to prioritize a whole VLAN (ID 17 in my case). Here is my configuration with comments:

# This is my traffic-qualifier (any):
traffic classifier EveryTraffic operator and
if-match any

# Here I'm increasing the priority to 5:
traffic behavior EveryTraffic 
remark dscp cs6
remark dot1p 5

# What should be done? Prioritize the traffic to level 5:
qos policy VeryHigh
classifier EveryTraffic behavior VoiceTraffic

# This will apply the policy to vlan 17 inbound and outbound:
qos vlan-policy VeryHigh vlan 17 inbound
qos vlan-policy VeryHigh vlan 17 outbound

I dialed an external number and Queue 5 packets are counting up:

display qos queue-statistics int g2/0/23 outbound
Interface: GigabitEthernet2/0/23
Direction: outbound
Forwarded: 3037 packets, 797734 bytes
Queue 0
  Forwarded: 0 packets, 0 bytes, 0 pps, 0 bps
  Current queue length: 0 packets
Queue 1
  Forwarded: 0 packets, 0 bytes, 0 pps, 0 bps
  Current queue length: 0 packets
Queue 2
  Forwarded: 0 packets, 0 bytes, 0 pps, 0 bps
  Current queue length: 0 packets
Queue 3
  Forwarded: 0 packets, 0 bytes, 0 pps, 0 bps
  Current queue length: 0 packets

  Forwarded: 0 packets, 0 bytes, 0 pps, 0 bps
  Current queue length: 0 packets
Queue 5
  Forwarded: 522 packets, 152673 bytes, 33 pps, 80824 bps
  Current queue length: 0 packets
Queue 6
  Forwarded: 0 packets, 0 bytes, 0 pps, 0 bps
  Current queue length: 0 packets
Queue 7
  Forwarded: 493 packets, 73338 bytes, 0 pps, 960 bps
  Current queue length: 0 packets

Wikipedia has a good documentation about the priority levels: https://en.wikipedia.org/wiki/IEEE_P802.1p

feel free to discuss about quality of service in the comments 🙂
