dhgroup [0] [1][2][3 ][4] | hash [md5 | sha1] | password [0 | 7] password [wwn wwn-id]}
no fcsp dhchap {devicename switch-wwn password [0 | 7] password |

Usage Guidelines You can only see the fcsp dhchap command if you enter the fcsp enable command.

Examples The following example enables FC-SP:
switch(config)# # fcsp enable
