to hosts that request them from sources outside the interface on which they reside.
Figure 17- 6. DHCP/BOOTP Relay
The BOOTP Relay Information menu is used to enable BOOTP Relay and configure hops and time limit. Set the relay
configuration as desired and click on the

button. These settings will be applied to all BOOTP/DHCP relays regardless
of the destination or source.
The following fields can be set:
Parameter
Description
BOOTP/DHCP Relay Status <
Disabled
>
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
BOOTP HOPS Count Limit [
4
]
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
.
BOOTP/DHCP Relay Time Threshold [
0
]
Allows an entry between
0

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.
