(Optional) Preventing Repeated IP Address Allocation

(Optional) Preventing Repeated IP Address Allocation

Context

Before assigning an address to a client, the switch used as the DHCP server needs to ping the IP address to avoid address conflicts.

After the dhcp server ping command is executed, the DHCP server can prevent repeated IP address allocation. The DHCP server pings an IP address to be allocated. If there is no response to the ping packet within a certain period, the DHCP server continues to send ping packets to this IP address until the number of ping packets reaches the maximum value. If there is still no response, this IP address is not in use, and the DHCP server allocates the IP address to a client.

Duplicate IP address detection on the DHCP server should not be too long. Otherwise, the client cannot obtain an IP address. It is recommended that the configured total detection time (Maximum number of send ping packets x Maximum response time) be smaller than 8s.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run dhcp server ping packet number

    The maximum number of ping packets to be sent by the switch is set.

    By default, the DHCP server sends 0 ping packets, indicating that no ping operation is performed.

  3. Run dhcp server ping timeout milliseconds

    The period in which the switch waits for the response to a ping packet is set.

    By default, the period in which the switch waits for the response to a ping packet is 500 ms.

  4. Run commit

    The configuration is committed.
