A  Gateway/firewall switch configuration 
This section details the configuration of an S4112F-ON switch used as the external gateway/simulated firewall 
to validate this deployment example. This switch is connected to the border leafs, Leaf3a and Leaf3b, as 
shown in Figure 12. 
A.1  Initial configuration 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.  Enable spanning tree protocol as a precaution against loops. Any spanning tree protocol type 
supported by the switch is acceptable. This example uses RSTP.
