Configuring NPV
To configure list of external interfaces per server interfaces, perform the following tasks:
Enable or Disable 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.
To enable or disable the global policy for disruptive load balancing, perform the following tasks:
Multiple VSAN Support
By grouping devices into different NPV sessions based on VSANs, it is possible to support multiple
VSANs at the NPV-enabled switch. The correct uplink must be selected based on the VSAN(s) that the
uplink can carry.
DPVM Configuration
When NPV is enabled, the following requirements must be met before you configure DPVM on the NPV
core switch:
Command
Purpose
Step 1
switch#
config t
switch(config)#
Enters configuration mode on the NPV.
Step 2
switch(config)#
npv traffic-map
server-interface
svr-if-range
external-interface
ext-if-range
switch (config)#
Allows you to configure a list of external
interfaces per server interfaces by specifying the
external interfaces in the svr-
if-range.
The
server to be linked is specified in the
ext-
if-range.
switch(config)#
no npv traffic-map
server-interface
svr-if-range
external-interface
ext-if-range
switch (config)#
Disables the NPV traffic management feature on
the NPV.
Command
Purpose

switch#
config t
switch(config)#

core switch.
Step 3
switch (config)#
no npv traffic-map
