Chapter 34 Configuring N Port Virtualization
Verifying NPV
To configure a traffic map, perform this task:
Note The traffic map configuration only takes effect after you reinitialize each of the server interfaces
specified in the map.
Enabling Disruptive Load Balancing
If you configure additional NP uplinks, you can enable the disruptive load-balancing feature to distribute
the server traffic load evenly among all the NP uplinks.
To enable disruptive load balancing, perform this task:
Note Enabling disruptive load balancing may force reinitialization of one or more server interfaces. This
action causes traffic disruption to the attached devices.
Verifying NPV
To display information about NPV, perform the following task:
Command Purpose
Step 1
switch# config t
switch(config)#
Enters configuration mode on the NPV.
Step 2
switch(config)# npv traffic-map
server-interface {fc slot/port | vfc vfc-id}
external-interface fc slot/port
switch (config)#
Configures a mapping between a server
interface (or range of server interfaces) and an
NP uplink interface (or range of NP uplink
interfaces).
switch(config)# no npv traffic-map
server-interface {fc slot/port | vfc vfc-id}
external-interface fc slot/port
switch (config)#
Removes the mapping between the specified
server interfaces and NP uplink interfaces.
Command Purpose
Step 1
switch# configure terminal
switch(config)#
Enters configuration mode on the NPV.
Step 2
switch(config)# npv auto-load-balance
disruptive
switch (config)#
Enables disruptive load balancing on the switch.
Step 3
switch (config)# no npv auto-load-balance
disruptive
Disables disruptive load balancing on the
switch.
Command Purpose
switch# show npv flogi-table [all]
Displays the NPV configuration.
