iSLB initiator configuration submode.
Command History
Usage Guidelines We recommend using the system-assign option. If you manually assign a WWN, you must ensure its
uniqueness. You should not use any previously-assigned WWN.
If you use system-assign option to configure WWNs for an iSLB initiator, when the configuration is
saved to an ASCII file, the system-assigned WWNs are also saved. If you subsequently perform a write
erase, you must manually delete the WWN configuration from the ASCII file. Failing to do so can cause
duplicate WWN assignments if the ASCII configuration file is reapplied on the switch.
Examples The following example uses the switch WWN pool to allocate the nWWN for this iSCSI initiator and to
keep it persistent.
switch# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# iscsi initiator name iqn.1987-02.com.cisco.initiator
switch(config-iscsi-init)# static nWWN system-assign
nwwn Configures the initiator node WWN hex value.
pwwn Configures the peer WWN for special frames.
wwn-id Specifies the pWWN or nWWN ID.
system-assign Generates the pWWN or nWWN value automatically.
