Configuring DHCHAP Passwords for Remote Devices

To locally configure the remote DHCHAP password for another switch in the fabric, perform this task:
Command
Step 1
switch# configuration terminal
Step 2
switch(config)# fcsp dhchap devicename
switch-wwn password password
switch(config)# no fcsp dhchap devicename
switch-wwn password password
The following example configures a clear text password for another switch in the fabric that is identified
by the switch WWN device name:
switch(config)# fcsp dhchap devicename 00:11:55:66:00:aa:bb:cc password 0 NewPassword
The following example configures a password entered in an encrypted format for another switch in the
fabric that is identified by the switch WWN device name:
switch(config)# fcsp dhchap devicename 00:11:22:33:55:aa:bb:cc password 7 asdflkjh
