Initiating A Disruptive Load-Balancing Process; Displaying And Maintaining Npv; Npv Configuration Example; Network Requirements - HP 5920 series Configuration Manual

Step
3. Configure a
downlink-to-uplink
interface mapping.

Initiating a disruptive load-balancing process

CAUTION:
This feature redistributes downlink traffic across all uplink interfaces for better load balancing, but it
causes traffic interruption.
If interfaces in a VSAN are not distributed evenly, you can use this feature to force all nodes in the VSAN
to relog in to the core switch.
To initiate a disruptive load-balancing process:
Step
1. Enter system view.
2. Enter VSAN view.
3. Initiate a disruptive load-balancing process.

Displaying and maintaining NPV

Execute display commands in any view.
Task
Display the nodes on downlink interfaces and their
mapped uplink interfaces.
Display the traffic mapping information.
Display status information.

NPV configuration example

Network requirements

As shown in
Command
npv traffic-map server-interface
interface-type interface-number
external-interface interface-type
interface-number
Figure 26, configure Switch A (edge switch) as an NPV switch to expand the network.
Remarks
By default, no mapping is configured.
