To configure a traffic map, perform this task:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# npv traffic-map
server-interface {fc slot/port | vfc vfc-id}
external-interface fc slot/port
switch (config)#
switch(config)# no npv traffic-map
server-interface {fc slot/port | vfc vfc-id}
external-interface fc slot/port
switch (config)#
The traffic map configuration only takes effect after you reinitialize each of the server interfaces
Note
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:
Command
Step 1
switch# configure terminal
switch(config)#
Step 2
switch(config)# npv auto-load-balance
disruptive
switch (config)#
Step 3
switch (config)# no npv auto-load-balance
disruptive
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
switch# show npv flogi-table [all]
