a.
DHCP Retries
To gain an IP address over DHCP, the port will send DHCP discovery messages into the network
expecting a DHCP server to respond. If it sees no response after the first message, it will send another
discovery message — this is known as a DHCP retry.
The DHCP Retries setting determines how many DHCP retries the port will make before falling back to a
link local IP Address.
To modify the number of DHCP retries the port will make, enter the new number into the 'DHCP
RETRIES' textbox, the default value is 3.
b.
DHCP Request Interval
The DHCP Request Interval sets the base time between DHCP discover attempts in milliseconds. The
time between DHCP discover messages is multiplied by two between the first message and the second
(first DHCP retry), then the time is multiplied by two again for the following message and so on up to a
limit of 64 seconds.
If a different base interval is required, enter the interval into the 'DHCP REQUEST INTERVAL (MS)'
textbox.
The default DHCP Request Interval is 4000 ms (4 seconds).
