About Password Configuration for Remote Devices
You can configure passwords in the local authentication database for other devices in a fabric. The other
devices are identified by their device name, which is also known as the switch WWN or device WWN.
The password is restricted to 64 characters and can be specified in clear text (0) or in encrypted text (7).
Note The switch WWN identifies the physical switch. This WWN is used to authenticate the switch and is
different from the VSAN node WWN.
Configuring DHCHAP Passwords for Remote Devices
To locally configure the remote DHCHAP password for another switch in the fabric using Fabric
Manager, perform this task:
Step 1 Right-click an ISL and choose Enable FC-SP from the drop-down list.
You see the Enable FC-SP dialog box as shown in Figure 23-5.

About the DHCHAP Timeout Value
During the DHCHAP protocol exchange, if the Nexus 5000 Series 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.
