Configure NSX-T bare metal edge management interface to use 2 interfaces

Products

• VMware NSX

Issue/Introduction

Symptoms:
By default the bare metal edge nodes uses a single interface for management.

Environment

VMware NSX-T Data Center
VMware NSX-T Data Center 2.x

Resolution

As a bare metal edge can support up to 8 interfaces, you may wish to add redundancy to the management network by using 2 interfaces.
It is possible to use 2 interfaces for the management network.


The management interface can be configured to use 2 interfaces:
Additionally, one can configure the management redundancy via LAG, however only one of the
LAG members can be active at a time.

The details on configuring this can be found in the NSX-T command line reference:
NSX-T Command-Line Interface Reference
Look for section:
set interface <interface-name> ip <prefix> gateway <gateway-ip> plane <plane> mode <mode> members <members> primary <primary>

The details are:
Create bond interface and set the plane property of the interface and config the IP address. If plane is set to mgmt, it is reported as such to the management plane (MP) via MPA, and the slave devices are not consumed by dataplane for dataplane operations.
You can configure the bond interface with a DHCP or static IP address. If you configure a static IP address, make sure an appropriate network route is also configured.

Allowed values: mgmt, debug
<mode>    Bond mode (e.g. active-backup)
Allowed values: active-backup
<members>    Bond member devices (e.g. eth0,eth1)
<primary>    Bond primary device (in active-backup mode, e.g. eth0)
