7.1 General settings
1. Enter configuration mode with the configure terminal command.
2. Configure the hostname.
3. If DHCP is not used, configure the OOB management IP address and default gateway.
4. Specify an NTP server accessible by the switch. In this example, this is an NTP server on the OOB
management network.
5. Enable RSTP as a precaution against loops. Configure S5248F-Leaf1A as the primary RSTP root
bridge using the spanning-tree rstp priority 0 command and S5248F-Leaf1B as the
secondary RSTP root bridge using the spanning-tree rstp priority 4096 command.

7.2 Configure port-groups
In this deployment example, S5248F-ON interfaces eth1/1/21-1/1/24 and 1/1/31 are connected to 10GbE Intel
X710 adapters on the S2D Ready Nodes and management system. These ports must be changed on the
switches from their native speed of 25GbE to 10GbE using the port-group command. See Appendix B for
more information on port-groups.
Note: 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 respectively.
1. Specify the port-group number.
2. Set the mode to 10GbE.
