PurposeCommand or Action

Step 1
Configures a password for another switch in the
fabric that is identified by the switch WWN device
name.
fcsp dhchap devicename switch-wwn password password
Example:
switch(config)# fcsp dhchap devicename
21:00:05:30:23:1a:11:03 password mypassword
Step 2
Removes the password entry for this switch from
the local authentication database.
switch(config)# no fcsp dhchap devicename switch-wwn
password password
Example:
switch(config)# no fcsp dhchap devicename
21:00:05:30:23:1a:11:03 password mypassword
Step 3
DHCHAP Timeout Value
During the DHCHAP protocol exchange, if the switch does not receive the expected DHCHAP message
within a specified time interval, authentication failure is assumed. The time ranges from 20 (no authentication
is performed) to 1000 seconds. The default is 30 seconds.
When changing the timeout value, consider the following factors:
•
The existing RADIUS and TACACS+ timeout values.
•
The same value must also be configured on all switches in the fabric.
Configuring the DHCHAP Timeout Value
You can configure the DHCHAP timeout value.
