B  S5248F-ON port groups 
In the example used in this guide, interface eth1/1/9 is connected to a 10GbE adapter on a PowerEdge server 
used as a jump box. On S5248F-ON, this interface must be changed from its native speed of 25GbE to 
10GbE using the port-group command. 
Note: In place of a jump box, a laptop computer containing a 1GbE BASE-T network adapter may be directly 
connected to an S5248F-ON leaf switch for VxRail deployment as described in Chapter 9. In this case, use an 
SFP-to-1GbE BASE-T adapter, Dell part number XTY28, in the leaf switch. Configure the corresponding 
S5248-ON port for 10GbE as described below. The switch port auto-negotiates to 1GbE when the laptop is 
connected.  
To determine the port-group-to-interface mapping, run the show port-group command: 
S5248F-Leaf1A# show port-group

In the output above, interface eth1/1/9 is in port-group 1/1/3 which is at its default setting of 25GbE. The 
commands to change the interfaces in port-group 1/1/3 from 25GbE to 10GbE are as follows: 
S5248F-Leaf1A# configure terminal 
S5248F-Leaf1A(config)# port-group 1/1/3 
S5248F-Leaf1A(conf-pg-1/1/3)# mode eth 10g-4x
