Npv Load-Balance Disruptive - HP 6127XLG Blade Series Command Reference Manual

Parameters
interval: Specifies a value for the delay timer, in the range of 1 to 300 seconds.
Usage guidelines
Only NPV switches and VSANs operating in NPV mode support this command.
The delay timer helps reduce network flapping caused by up/down events of uplink interfaces. If the link
layer state of uplink interfaces is stable, set the delay timer to a smaller value. Otherwise, set the delay
timer to a greater value.
Examples
# Set the delay timer for automatic load balancing to 20 seconds in VSAN 1.

Usage guidelines
Only NPV switches and VSANs operating in NPV mode support this command.
If the traffic load is not distributed evenly across the interfaces in a VSAN, you can use this command to
manually initiate a disruptive load balancing process. Then, downlink interfaces that are moved to a
different uplink interface are reinitialized, and the nodes connected to moved downlink interfaces log in
again to the core switch.
This feature redistributes downlink traffic across all uplink interfaces for better load balancing. However,
it causes traffic interruption on the nodes connected to moved downlink interfaces.
Examples
# Manually initiate a disruptive load balancing process in VSAN 1.
