Dell VxRail Network Planning Guide

Set up the network switch ports for VxRail connectivity

Once the switch base settings are complete, the next step is to set up the switch ports.

1. Configure the MTU size if using jumbo frames.
2. Set the port to the appropriate speed or to auto-negotiate speed.
3. Set spanning tree mode to disable transition to a blocking state, which can cause a timeout condition.
4. Enable flow control receive mode and disable flow control transmit mode.
5. Configure the External Management VLAN (Row 1) on the switch ports. If you entered Native VLAN, set the ports on the switch to accept untagged traffic and tag it to the native management VLAN ID. Untagged management traffic is the default management VLAN setting on VxRail.
6. For VxRail version 4.7 and later, configure the Internal Management VLAN (Row 2) on the switch ports.
7. If required, allow multicast on the VxRail switch ports to support the Internal Management network.
8. Configure a VMware vSphere vMotion VLAN (Row 3) on the switch ports.
9. Configure a vSAN VLAN (Row 4) on the switch ports. Allow unicast traffic on this VLAN.
10. Configure the VLANs for your VM Networks (Rows 6) on the switch ports.
11. Configure the optional vCenter Server Network VLAN (Row 7) on the switch ports.
12. Configure the optional VxRail Witness Traffic Separation VLAN (Row 69) on the switch ports, if required.

    If link aggregation is configured on the switchport, some settings are configured on the port channel, and some are configured on the interface:

    • Configure the appropriate port channel or equivalent, depending on the switch operating system on the switch port.
    • Configure any additional network port settings that do not transfer from the port channel on the switch port.
