Setting Automatic Link Aggregation on ESXi-facing Ports for vCenter

Currently, automatic Link Aggregation (LAG) is only supported between Pluribus Networks switches. With this feature, automatic Link Aggregation (LAG) includes ports between Pluribus Networks switches and ESXi hosts.

Netvisor ONE implements LLDP and LACP to bundle the ports. Since there are no custom type-length-value (TLV) probes, Netvisor ONE implements standard LLDP TLVs to uniquely identify ESXi hosts. The system description TLV is used to identify ESXi hosts and the system name is used to uniquely identify a specific ESXi host.

LACP mode is enabled and set to active on auto-lag with a fallback-option of individual to ensure that there is extra robustness in bundling and ensure that ports are bundled only if ESXi host is running LACP to avoid any data path issues.


You can enable or disable trunking towards hosts (default value is off).


The current global parameter auto-trunk needs to be ON (default) for this new settings to take effect. Setting auto-trunk to off turns off all trunking.

Example output from trunk-show, port-show and lldp-show.
