minimum-wait-time
Syntax minimum-wait-time seconds;
Hierarchy Level [edit forwarding-options helpers bootp],
[edit forwarding-options helpers bootp interface (interface-name | interface-group)]
Release Information Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS Release 9.0 for EX Series switches.
Statement introduced in Junos OS Release 11.3 for QFX Series switches.
Description Set the minimum allowed number of seconds that the BOOTP client has waited before
packets are forwarded, based on the secs field in the BOOTP request message. If the
value of minimum-wait-time is less than the value of the secs field in the BOOTP request
message, the packet is not forwarded to the BOOTP servers and relay agents that are
configured at the hierarchy level of this statement. You can use the minimum-wait-time
statement to determine which servers the device should forward packets to based on
how long the BOOTP client has been waiting to receive a BOOTP reply from a server.
The BOOTP client sets the secs field in the BOOTP request to reflect the number of
seconds elapsed since the client began address acquisition or a renewal process.
The default value for the minimum wait time is zero (0) seconds. If the minimum wait
time is 0 and the secs field in the BOOTP request message is 0, the device forwards the
packet.
Options seconds—Minimum wait time the BOOTP client has waited before packets are forwarded.
Range: 0 to 30,000
Default: 0
