This set of sample syntax is for providing basic guidance on the settings that must be performed on the top-of-rack switches to configure VLANs and a switch port for a Cloud Foundation on VxRail deployment, and configuring a switch support BGP peering for the Application Virtual Network (AVN). The actual code that is required on the top-of-rack switches depends on the existing data center network infrastructure, switch operating system and routing standards.

The sample syntax highlights the following required items:

• VLAN for VxRail external management
• VLAN fir VxRail internal management – node discovery
• VLAN for NSX host overlay network – with DHCP helper
• Switch port configuration for VxRail node

interface vlan <VxRail External Management>

The sample syntax highlights the following required items:

• VLANs for AVN uplinks with assigned IP addresses
• Prefix list to permit route filtering for routes from the AVN
• BGP External ASN setting
• BGP peering with the pair of AVN Edge Service Gateways
