Description
Operating system
Dell OS 9 and 10
Application
IXExplorer 6.70 - IXIA
Switch
S4048-ON, S4128F-ON
OS 9 based switch configuration – Switch on the left side labeled “S4048-ON-3”
1. Trust the dot1p Class of service values to queue assignment configured by the operating system.
a. Switch(config)# service-class dynamic dot1p
2. Create the dcb map configuration. In this configuration pfc and ets are enabled.
a. Switch(config)# dcb-map <name>
b. Switch(config-dcbmap-name)# priority-group 0 bandwidth 1 pfc off
LAN traffic is given 1% of its 10GE bandwidth and it will not generate PFC grames
towards the sender (Ixia).
c. Switch(config-dcbmap-name)# priority-group 1 bandwidth 99 pfc on
iSCSI traffic is given 99% of its 40GE bandwidth and it will generate PFC frames towards the
sender (Ixia).
d. Switch(config-dcbmap-name)# priority-pgid 0 0 0 0 1 0 0 0
Assign the priority group to the corresponding class of service. In this case, CoS 4 is
configured with priority group 1.
3. Assign the dcb map to the all the interfaces receiving and transmitting these two types of traffic.
a. Switch(config)# inter Te1/3
b. Switch(config-if-te-1/3)# dcb-map <name>
c. Switch(config-if-te-1/3)# end
Remember to configure the switchports connected to the ixia traffic generator as spanning-tree edge port.
This configuration tells the switch that edge ports are to transition into forwarding mode straight away and not
participate into any spanning-tree negotiations.
