Quality of Service scenarios and configuration HP Series 2530 Switches

This configuration review written based on official HP Advanced Traffic Management Guide with some scenarios added to clearify topics not fuly covered in the official guide. In this review you can find various configuration scenarios on QoS deployment for HP 2530 Series switches with detailed explanations how to deploy one or another QoS method/technique to achieve required results. This switch software review is intended for network administrators and support personnel who wants to depoly QoS service in low-price HP configurable switches.

Inside this review (one of scenarios):

Let's consider another example when central Core switch connects Edge switches with running services on them. On edge switches SW1, SW2, SW3 we will be prioritizing the services traffic using DSCP policy prioritization and on core switch CoreSW the traffic will be prioritized using QoS VLAN-ID Priority with 802.1p prioritization on tagged (trunk) ports.

So switches SW1, SW2, SW3 must honor the priotity (different types of traffic priority) from CoreSW switch and also change the dscp policies to a new ones. CoreSW is a transit switch but it should also set required priorities to types of traffic for vlans which move through tagged ports.

Let's beging with SW1 configuration:

SW1(config)# qos dscp-map 010100 priority 1
SW1(config)# qos dscp-map 011110 priority 5 
SW1(config)# qos dscp-map 101110 priority 7

We can see that Storage Service coming from SW2 and Internet Service from SW3 have different priorities than on SW1, thus we should apply DSCP policy to have new priorities set on SW1. First we create dscp priorities for services running on edge switches and then set dscp policies for that services on SW1.

SW1(config)# qos dscp-map 001111 priority 5
SW1(config)# qos type-of-service diff-services 001111 dscp 011110 
SW1(config)# qos dscp-map 001010  priority 1
SW1(config)# qos type-of-service diff-services 001010 dscp 010100
SW1(config)# vlan 10 qos dscp 20 
SW1(config)# vlan 30 qos dscp 30 
SW1(config)# vlan 40 qos dscp 46 

SW1(config)# show qos type-of-service
