ISL connection on either a leaf or spine switch, it assigns the ISL to the untagged member of this VLAN. IP address from reserved range is used for this VLAN. eBGP session is started on the VLAN interface. • Global untagged VXLAN VLAN 4080 - SFS automatically configures VXLAN overlay networks with EVPN to extend networks between racks in a multirack deployment. VLAN 4080 with automatic IP addresses from the reserved range is used for leaf-to-leaf ICL links. VXLAN requires one VLAN to be assigned globally for untagged port-scoped VLAN (Port, VLAN) pairs. • Internal BGP (iBGP) ICL VLAN 4090 - SFS automatically configures iBGP peering between a pair of leaf switches directly connected over ICL links. VLAN 4090 is created automatically with IP addresses from reserved range for enabling iBGP sessions between the VLT peer switches. • VLAN 4094 - SFS automatically creates VLAN 4094 on all leaf switches. This VLAN is used for all VLT control traffic between two VLT peer switches and is added on the VLT ICL ports on leaf switches. • Default client management network VLAN 4091 - SFS automatically configures an overlay network that is called client_Management_Network. When a device is connected automatically on to the network fabric, the switch uses the VLAN mapped to this overlay network. VLAN 4091 is used as the default client management VLAN for the VXLAN network. • Default client control network - SFS configures a second overlay network that is called Client_Control_Network for VxRail integrated solutions. VLAN 3939 is used as the default client control VLAN for this VxLAN network. You can change the VLAN associated with the network, but it is not recommended to change it for VxRail solution deployments. To check the VLAN configuration formed in SFS-VxRail deployment, use show virtual-network command. Following is the example output: OS10# show virtual-network Codes: DP - MAC-learn Dataplane, CP - MAC-learn Controlplane, UUD - Unknown-Unicast-Drop Un-tagged VLAN: 4080 Virtual Network: 3939 Description: In-band SmartFabric Services discovery network VLTi-VLAN: 3939 Members: VLAN 3939: port-channel1000, ethernet1/1/12, ethernet1/1/13 VxLAN Virtual Network Identifier: 3939 Source Interface: loopback2(172.30.0.0) Remote-VTEPs (flood-list): 172.30.0.1(CP) Virtual Network: 4091 Description: Default untagged network for client onboarding VLTi-VLAN: 4091 Members: Untagged: ethernet1/1/12, ethernet1/1/13 VLAN 4091: port-channel1000 VxLAN Virtual Network Identifier: 4091 Source Interface: loopback2(172.30.0.0) Remote-VTEPs (flood-list): 172.30.0.1(CP) SmartFabric Services logical entities There are three types of logical entities that are defined for the SmartFabric Services: Networks, uplinks, and server profiles. Networks Networks are SmartFabric services templates that are populated once and then can be associated with servers, uplinks, or interfaces. With in the context of SmartFabric services, you can define the following four types of networks: • General purpose networks • VXLAN networks • L3 VLAN networks • L3 Routed networks General purpose networks General purpose networks are L2 VLAN networks in VxRail and L2 VXLAN networks in L3 fabric. For L3 fabric, SmartFabric services automatically creates a virtual network corresponding to a network. This virtual network has one-toone mapping with the network, which means for each VLAN, there exists a virtual network with VNI same as the VLAN ID. VXLAN networks VXLAN network extends L2 connectivity over an underlay L3 connected network. Association of VXLAN network to interface creates a binding and associates this interface to VXLAN bridge.
