Configuring NPV Traffic Management

The NPV traffic management feature is enabled after configuring NPV. Configuring NPV traffic
management involves configuring a list of external interfaces to the servers, and enabling or disabling
disruptive load balancing.

Configuring List of External Interfaces per Server Interface

A list of external interfaces are linked to the server interfaces when the server interface is down, or if the
specified external interface list includes the external interface already in use.
To configure the list of external interfaces per server interface, perform the following tasks:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# npv traffic-map
server-interface svr-if-range
external-interface fc ext-fc-if-range
switch (config)#
switch(config)# npv traffic-map
server-interface svr-if-range
external-interface port-channel
ext-pc-if-range
switch (config)#
switch(config)# no npv traffic-map
server-interface svr-if-range
external-interface ext-if-range
switch (config)#
1.While mapping non-PortChannel interfaces and PortChannel interfaces to the server interfaces, include
them separately in two steps.

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:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# npv auto-load-balance disrup-
tive
switch (config)#
Step 3
switch (config)# no npv auto-load-balance
