Deployment Guide

35 VxFlex Network Deployment Guide using Dell EMC Networking 25GbE switches and OS10EE
In the switch configuration section, a policy map is created and instructs both switches to trust the DSCP
value mapping. The configuration below shows the commands set to trust DSCP value mapping for the
S5248F-ON switch. Configuration for the second leaf switch is identical.
S5248-Leaf1A(config)# interface range ethernet1/1/1-1/1/4
S5248-Leaf1A(conf-range-eth1/1/1-1/1/4)# trust-map dscp default
DSCP values are inserted on a port-group basis. In the table below two port groups are enabled to filter
traffic, atx01-w01-vds01-management, and atx01-w01-vds01-VxFlex-management. To create markings
navigate to Home > Networking > port group > Edit > Traffic filtering and markings. Table 19 shows the
values that are used.

The show qos interface ethernet interface_number command is used to confirm that DSCP is
enabled on the interface.
