Configure the interfaces for the jump box or laptop computer connections to be used during VxRail deployment. This example uses 10 GbE interface 1/1/9:1 on Leaf1A.
Note: See
Appendix B to change the native speed of S5248F-ON port groups from 25 GbE to 10 GbE for jump box or laptop computer connections. When the port-group on the S5248F-ON switch is set to 10 GbE, the interface will auto-negotiate to 1 GbE if a 1 GbE optic is being used.
While only one connection to the jump box is required, two may be used for redundancy. Add these interfaces as access ports on VLAN 1811 (the External Management VLAN).
Note: For this deployment guide, the DNS and NTP services for the VxRail cluster are on the upstream external network. If these services are on other devices, ensure the corresponding switch interfaces are also in the External Management VLAN.
Configure the interfaces for connections to the VxRail nodes. Interfaces 1/1/25 through 1/1/28 are used in this example.
Use the switchport mode trunk command to enable ports to carry traffic for multiple VLANs. Configure the ports as access (untagged) ports on VLAN 1811 (External Management VLAN). Configure the ports as trunk (tagged) ports on VLANs 1812-1815, and 3939 (the vMotion, vSAN, VM Networks, and Internal Management VLANs). Enable jumbo frames on the VLANs with the mtu 9216 command.
Configure ports directly connected to nodes, servers, or other endpoints as STP edge ports. Set flow control to receive on and transmit off on node-connected ports as a best practice.
Note: Flow control is enabled on all network interfaces in ESXi by default.
