Default Dhcp Server Values - Dell Networking N4000 Series Configuration Manual

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 1087.

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.
