menu path lets you configure S4224 DHCP Server, DHCP Snooping, and
DHCP Relay parameters.
DHCP (Dynamic Host Configuration Protocol) is a used for assigning dynamic IP addresses to devices on
a network. DHCP used by networked computers (clients) to obtain IP addresses and other parameters
such as the default gateway, subnet mask, and IP addresses of DNS servers from a DHCP server.
The DHCP server ensures that all IP addresses are unique, for example, no IP address is assigned to a
second client while the first client's assignment is valid (its lease has not expired). The IP address pool
management is done by the server and not by a person.
The

DHCP
menu path lets you configure S4224 DHCP Snooping and/or DHCP Relay,
as discussed below. Note that you can not access the S4224 by System Name via DHCP/DNS.
Note

This page configures global mode and VLAN mode to enable/disable DHCP server per system and per
VLAN. A DHCP Server is used to allocate network addresses and deliver configuration parameters to
dynamically configured hosts called DHCP client.
Click the
Add VLAN Range
button to display the entry fields.
Note
: after power up, the S4224 has DHCP enabled. If a DHCP server is available, the S4224 will obtain
an IP address from the DHCP server. If no DHCP server is available, after 70 seconds, the S4224 will fall
back to the default IP address of 192.168.0.1/24.
The parameter entries are described below.
