About the DHCHAP Timeout Value
During the DHCHAP protocol exchange, if the MDS 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
To configure the DHCHAP timeout value using Fabric Manager, follow these steps:
Step 1 Expand Switches > Security and then select FC-SP.
You see the FC-SP configuration in the Information pane.
Step 2 Click the General/Password tab.
You see the DHCHAP general settings mode for each switch (see Figure 45-7).

Step 3 Change the DHCHAP timeout value for each switch in the fabric.
