DHCP/BOOTP Relay

The DHCP/BOOTP Relay Hops Count Limit allows the maximum number of hops (routers) that the DHCP/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.

This field allows an entry between 1 and 16 to define the maximum number of router hops
DHCP/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 DHCP/BOOTP 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.
This field can be toggled between Enabled and Disabled using the pull-down menu. It is
used to enable or disable the DHCP Agent Information Option 82 on the Switch. The
