About the DHCHAP Timeout Value

During the DHCHAP protocol exchange, if the Cisco 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.
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.
