ip helper forward delay
Sets the forward delay time value for the DHCP Relay configuration. The BOOTP/DHCP packet the client
sends contains the elapsed boot time. This is the amount of time, in seconds, since the client last booted.
DHCP Relay will not process the packet unless the client’s elapsed boot time value is equal to or greater
than the configured value of the forward delay time.
ip helper forward delay seconds
Syntax Definitions
seconds Forward delay time value in seconds (1–65535). Do not use commas in
the value.
Defaults
By default, the forward delay time is set to three seconds.
Platforms Supported

Usage Guidelines
• The time specified applies to all defined IP helper addresses.
• If a packet contains an elapsed boot time value that is less than the specified forward delay time value,
DHCP Relay discards the packet.
Examples
-> ip helper forward delay 300
-> ip helper forward delay 120
