7.1.2 Configure interfaces
Configure the interfaces for the jump box or laptop computer connections to be used during VxRail
deployment. This example uses interface twentyFiveGigE 1/9 on each switch. While only one connection is
required, two are used for redundancy.
Note: In this example, the jump box also provides DNS and NTP services as covered in Section 5.4
. If these
services are located on other devices, ensure the switch interfaces connected to these services are
configured in the same manner.
Configure the interfaces for connections to the VxRail nodes. Interfaces twentyFiveGigE 1/17 through 1/20
are used in this example.
Use the portmode hybrid command to enable ports to carry both untagged (in-band management) and
tagged (all other) traffic. Put the ports in Layer 2 mode with the switchport command. Configure ports
directly connected to nodes, servers, or other endpoints as RSTP edge ports. Set flow control to “rx on tx off”
on node-connected ports as a best practice.
Note: Flow control is enabled on all network interfaces in ESXi by default.
