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 Port-group port-group1/1/1 port-group1/1/2 port-group1/1/3 port-group1/1/4 port-group1/1/5 port-group1/1/6 port-group1/1/7 port-group1/1/8 port-group1/1/9 port-group1/1/10 port-group1/1/11 port-group1/1/12 port-group1/1/13 port-group1/1/14 port-group1/1/15 port-group1/1/16 port-group1/1/17 port-group1/1/18 Mode Eth 25g-4x Eth 25g-4x Eth 25g-4x Eth 25g-4x Eth 25g-4x Eth 25g-4x Eth 25g-4x Eth 25g-4x Eth 25g-4x Eth 25g-4x Eth 25g-4x Eth 25g-4x Eth 100g-2x Eth 100g-2x Eth 100g-1x Eth 100g-1x Eth 100g-1x Eth 100g-1x Ports FEM 1 2 3 4 - 5 6 7 8 - 9 10 11 12 - 13 14 15 16 - 17 18 19 20 - 21 22 23 24 - 25 26 27 28 - 29 30 31 32 - 33 34 35 36 - 37 38 39 40 - 41 42 43 44 - 45 46 47 48 - 49 50 - 51 52 - 53 - 54 - 55 - 56 - 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. 59 Dell EMC Solutions for Microsoft Azure Stack HCI Networking Guide
