4.5.7 Configuring Ping
Times
By default, when trying to assign an IP address from the DHCP address pool to
a DHCP client , the DHCP server will ping the IP address twice (one packet for
each time). If there is no response, the DHCP server considers this address an
idle address and assigns it to the DHCP client. If there is a response, the DHCP
server considers that this address is in use and tries to assign another address
to the DHCP client until an address is assigned successfully.
To configure the number of Ping packets, execute the following commands in
the global configuration mode:
Command Function
DES-7200(config)# ip dhcp ping
packets number
Configure the number of Ping packets
before the DHCP server assigns an
address. If it is set to 0, the Ping operation
is not performed. The default value is 2.
4.5.8 Configuring Ping
Packet Timeout
By default, the DHCP server considers the IP address inexistent if it has not
received a response within 500 milliseconds after pinging an IP address. You
can adjust the Ping packet timeout.
To configure the Ping packet timeout, execute the following commands in the
global configuration mode:
Command Function
DES-7200(config)# ip dhcp ping
timeout milliseconds
Configure the Ping packet timeout for the
DHCP server. The default value is 500ms.
