What Additional Dhcp Features Does The Switch Support; Default Dhcp Server Values - Dell PowerConnect 8024 User Configuration Manual

What Additional DHCP Features Does the Switch Support?

The switch software includes a DHCP client that can request network
information from a DHCP server on the network during the initial system
configuration process. For information about enabling the DHCP client, see
"Setting the IP Address and Other Basic Network Information" on page 105.
If the switch is functioning as a Layer 3 device, the Layer 3 DHCP Relay
Agent can relay DHCP messages between DHCP clients and DHCP servers
that are located in different IP subnets.
The DHCP Layer 2 Relay feature permits Layer 3 Relay agent functionality in
Layer 2 switched networks. The switch supports L2 DHCP relay
configuration on individual ports, link aggregation groups (LAGs) and
VLANs. For information about Layer 2 and Layer 3 DHCP Relay, see
"Configuring L2 and L3 Relay Features" on page 899.
DHCP Snooping is a security feature that monitors DHCP messages between
a DHCP client and DHCP server. It filters harmful DHCP messages and
builds a bindings database of (MAC address, IP address, VLAN ID, port)
tuples that are specified as authorized. DHCP snooping can be enabled
globally and on specific VLANs. For information about DHCP Snooping, see
"Snooping and Inspecting Traffic" on page 751.

Default DHCP Server Values

By default, the DHCP server is disabled, and no address pools are configured.
You must create at least one address pool and enable the DHCP server to
allow the switch to dynamically assign network information to hosts with
DHCP clients that broadcast requests.
The DHCP server can lease a maximum of 256 addresses.
