B Port-groups
In this deployment guide, S5248F-ON interfaces eth1/1/21-1/1/24 and 1/1/31 are connected to 10GbE Intel
X710 adapters. These interfaces must be changed from their native speed of 25GbE to 10GbE. This is done
on S5248F-ON switches using the port-group command.
Note: The port-group command is used in Section 7.2 of this guide.
To determine the port-group-to-interface mapping, run the show port-group command:
S5248F-Leaf1A# show port-group

In the output above, interfaces eth1/1/21-1/1/24 are in port-group 1/1/6, and interface eth 1/1/31 is in port
group 1/1/8. The commands to change the interfaces in the two port-groups from 25GbE to 10GbE are as
follows:
S5248F-Leaf1A# configure terminal
S5248F-Leaf1A(config)# port-group 1/1/6
S5248F-Leaf1A(conf-pg-1/1/6)# mode eth 10g-4x
S5248F-Leaf1A(conf-pg-1/1/6)# port-group 1/1/8
S5248F-Leaf1A(conf-pg-1/1/8)# mode eth 10g-4x
After a port group mode change is made, the interface naming will change from eth 1/1/x to eth 1/1/x:n; where
x is the physical port number, and n is the logical port number. In this example, changing interfaces
eth1/1/21-1/1/24 and 1/1/31 to 10GbE also changes the interface names to eth1/1/21:1– 1/1/24:1 and
1/1/31:1.
Port-group configuration options for the S5248F-ON are shown in Table 19.
