Configuring N Port Virtualization
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.
This section includes the following topics:
• Configuring List of External Interfaces per Server Interface, page 7-12
• Enabling the Global Policy for Disruptive Load Balancing, page 7-13
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.
Detailed Steps
To configure the list of external interfaces per server interface, perform the following tasks:
Step 10
switch(config)# vsan database
switch(config-vsan-db)# vsan 12 interface fc
1/1 - 6
switch(config-vsan-db)# vsan 13 interface fc
1/1 - 6
Configures the port VSANs for the F ports on
the NPV device.
Step 11
switch(config-npv)# no npv enable
switch(config)#
Terminates session and disables NPV mode,
which results in a reload of the NPV device.
Command Purpose
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 fc
ext-fc-if-range
switch (config)#
Allows you to configure a list of external FC
interfaces per server interface by specifying the
external interfaces in the svr-if-range
.
The
server to be linked is specified in the
ext-fc-if-range.
switch(config)# npv traffic-map
server-interface
svr-if-range
external-interface port-channel
ext-pc-if-range
switch (config)#
Allows you to configure a list of external
PortChannel
1
interfaces per server interface by
specifying the external interfaces in the
svr-if-range. The server to be linked is specified
in the ext-pc-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.
1. While mapping non-PortChannel interfaces and PortChannel interfaces to the server interfaces, include them separately in two steps.
