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

Allows you to configure a list of external FC interfaces per server or range of interfaces by specifying
the external interfaces in the ext-fc-if-range. The servers to be linked are specified in the svr-if-range.
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.
Enabling or Disabling 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
