Verifying NPV Configuration

Enabling the Global Policy for Disruptive Load Balancing

Disruptive load balancing allows you to review the load on all the external interfaces and balance the load disruptively. Disruptive load balancing is done by moving the servers using heavily loaded external interfaces, to the external interfaces running with fewer loads.

Detailed Steps

To enable or disable the global policy for disruptive load balancing, perform the following tasks:

	Command	Purpose
Step 1
	switch# config t	Enters configuration mode on the NPV.
	switch(config)#
Step 2
	switch(config)# npv auto-load-balance disrup-	Enables disruptive load balancing on the NPV
	tive	core switch.
	switch (config)#
Step 3
	switch (config)# no npv auto-load-balance	Disables disruptive load balancing on the NPV
	disruptive	core switch.

This section includes the following topics:

•Verifying NPV, page 7-14

•Verifying NPV Traffic Management, page 7-15

To display NPV configuration information, perform one of the following tasks:

Command	Purpose
show fcns database	Displays all the NPV devices in all the VSANs
	that the aggregator switch belongs to.
show fcns database detail	Displays additional details such as IP addresses,
	switch names, interface names about the NPV
	devices.
show npv flogi-table	Displays a list of the NPV devices that are logged
	in, along with VSANs, source information,
	pWWNs, and FCIDs.
show npv status	Displays the status of the different servers and
	external interfaces.
show npv traffic-map	Displays the NPV traffic map.
show npv internal info traffic-map	Displays the NPV internal traffic details.
