The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes the Cisco NX-OS Fibre Channel, virtual Fibre Channel, and Fibre Channel over Ethernet (FCoE) commands that begin with W.
To allocate a secondary MAC address to a SAN node, use the wwn secondary-mac command.
wwn secondary-mac wwn-id range address-range
wwn-id |
Secondary MAC address with the format hh:hh:hh:hh:hh:hh. |
range address-range |
Specifies the range for the specified WWN. The only valid value is 64. |
Global configuration mode
|
|
4.0(0)N1(1a) |
This command was introduced. |
This command cannot be undone.
Changes to the worldwide names are only performed as required. They should not be changed on a daily basis. These changes should be made by an administrator or individual who is completely familiar with switch operations.
This example shows how to allocate a secondary range of MAC addresses:
switch(config)# wwn secondary-mac 00:99:55:77:55:55 range 64

show wwn |
Displays the status of the WWN configuration. |
To configure a WWN for a suspended Virtual SAN (VSAN) that has interop mode 4 enabled, use the wwn vsan command. To discard the configuration, use the no form of this command.
wwn vsan vsan-id vsan-wwn wwn
no wwn vsan vsan-id vsan-wwn wwn
vsan-id |
VSAN ID. The range is from 1 to 4093. |
vsan-wwn wwn |
Specifies the WWN for the VSAN. The format is hh:hh:hh:hh:hh:hh:hh:hh. |
None
Global configuration mode

4.0(0)N1(1a) |
This command was introduced. |
This command can succeed only if the following conditions are satisfied:
•The VSAN must be suspended.
•The VSAN must have interop mode 4 enabled before you can specify the switch WWN for it.
•The switch WWN must be unique throughout the entire fabric.
•The configured switch WWN must have McData OUI [08:00:88].
This example shows how to assign a WWN to a VSAN:
switch(config)# wwn vsan 100 vsan-wwn 20:64:08:00:88:0d:5f:81
switch(config)# vsan database
switch(config-vsan-db)# vsan 100 suspend
switch(config-vsan-db)# exit
switch(config)# wwn vsan 100 vsan-wwn 20:64:08:00:88:0d:5f:81
