DHCP / BOOTP Relay

The BOOTP hops count limit allows the maximum number of hops (routers) that the BOOTP messages can be relayed
through to be set. If a packet's hop count is more than the hop count limit, the packet is dropped. The range is between 1
and 16 hops, with a default value of 4. The relay time threshold sets the minimum time (in seconds) that the Switch will
wait before forwarding a BOOTREQUEST packet. If the value in the seconds field of the packet is less than the relay time
threshold, the packet will be dropped. The range is between 0 and 65,536 seconds, with a default value of 0 seconds.

Description
This field can be toggled between Enabled and Disabled using the pull-down menu.
It is used to enable or disable the BOOTP/DHCP Relay service on the Switch. The
default is Disabled
This field allows an entry between 1 and 16 to define the maximum number of router
hops BOOTP messages can be forwarded across. The default hop count is 4.
Allows an entry between 0 and 65535 seconds, and defines the maximum time limit
for routing a BOOTP/DHCP packet. If a value of 0 is entered, the Switch will not
process the value in the seconds field of the BOOTP or DHCP packet. If a non-zero
value is entered, the Switch will use that value, along with the hop count to determine
whether to forward a given BOOTP or DHCP packet.
