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.
