max-empty-replies (DHCP Local Server)



Hierarchy Level

Release Information

Statement introduced in Junos OS Release 16.1.


Specify the maximum number of empty replies that the DHCP local server sends to a specific requestor. When the maximum number is reached, the DHCP server closes the connection.

An empty reply is a response sent from the DHCP local server that contains no bindings or has an option status code error. Empty replies are often the response to an unauthorized requestor that has sent an invalid or incorrect query that produces no binding information. By limiting the number of empty replies that the DHCP local server can send, you prevent the connection from being consumed by an unauthorized or malicious requester, and free up the DHCP local server to support legitimate requestors.


number-of-repliesNumber of empty replies the DHCP local server sends before the connection is terminated.

Range: 1 through 100
