To resolve this issue, you must:
1. Configure a matching interface for pool netdhcp2-40.1.1.1/24 matches 40.1.1.0/24.
OS10(config)# interface ethernet 1/1/2
OS10(conf-if-eth1/1/2)# no shutdown
OS10(conf-if-eth1/1/2)# no switchport
OS10(conf-if-eth1/1/2)# ip address 40.1.1.1/24
2. Run the show ip interface brief command to verify if an IP address is assigned to ethernet 1/1/2 port.
OS10# show ip interface brief

3. Re-enable the DHCP server because it failed to start initially.
OS10# configure terminal
OS10(config)# ip dhcp server
OS10(config-dhcp)# disable
OS10(config-dhcp)# no disable
OS10(config-dhcp)#
Configuration notes
All Dell EMC PowerSwitches except MX-Series, S4200-Series, S5200 Series, and Z9332F-ON:
●
Before you configure a DHCP address pool, you must configure a DHCP server interface with an IP address in the range
that is used in the DHCP address pool. If you configure the DHCP address pool first, and then configure a DHCP server
interface, to enable automatic DHCP address allocation, you must restart the DHCP service using the disable and no disable
commands. Select one of the choices for successfully configuring a DHCP address pool:
○ Configure manual binding for a host/hardware MAC address in the IP address range that is used for the DHCP pool.
○ Configure a network statement with a valid IP address range.
● DHCP client is enabled by default on the management interface. The management interface automatically tries to obtain an
IP address from a DHCP server. To manually configure an IP address on the management port, disable the DHCP client using
the no ip address dhcp command in Interface mode
● The DHCP server does not start unless at least one interface matches one of the configured network pools. An interface
matches a network pool when you include the IP address in the subnet that is defined for that network pool. For example, an
interface with IP address 10.1.1.1/24 matches a pool that is configured with network 10.1.1.0/24.
Packet format and options
The DHCP server listens on port 67 and transmits to port 68. The DHCP client listens on port 68 and transmits to port 67.
