Command History
Usage Guidelines Disruptive load-balancing can be configured only in NPV mode.
When disruptive load-balancing is enabled, NPV redistributes the server interfaces across all available
NP uplinks when a new NP uplink becomes operational. To move a server interface from one NP uplink
to another NP uplink, NPV forces reinitialization of the server interface so that the server performs a
new login to the core switch. This action causes traffic disruption on the attached end devices.
To avoid disruption of server traffic, enable this feature only after adding a new NP uplink, and then
disable it again after the server interfaces have been redistributed.
Examples The following example shows how to enable disruptive load-balancing:
switch(config)# npv auto-load-balance disruptive
