There are two types of Network Failure Detection options available in
ESXi to detect network failure. It determines uplink status.
- Link Status Only
- Beacon Probing
Link Status only is very
simple, default option and recommended setting for most of the designs, as
shown in the video it will detect if physical NIC or cable issue till the connected
upstream switch only. It is similar to some kind of Layer 1 (Physical Layer) faults
in networking.
Beacon Probing as name
implies it broadcasts beacon through one uplink and hear it on another uplink. It
will detect network failures beyond the connected upstream switches, if you are
planning to use this setting it is recommended at lease have 3 NICs connected,
(With at least 3 NICs connected esxi can detect correct failure as shown in the
video).
Although it looks like Beacon Probing is very fancy settings but still
it is used less in esxi production environment. Due to Drops beyond the
upstream switch can cause esxi to think NIC is down.
