DHCP Relay Global Settings
This window is used to enable and configure DHCP Relay Global Settings on the Switch. The relay hops count limit
allows the maximum number of hops (routers) that the DHCP 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 DHCP REQUEST 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.
To view this window, click Network Application > DHCP > DHCP Relay > DHCP Relay Global Settings, as shown
