DHCP <POOL> mode
show config
After an IP address is leased to a client, only that client may release the address. The system performs a IP
+ MAC source address validation to ensure that no client can release another clients address. This
validation is a default behavior and is separate from IP+MAC source address validation.
Configuration Tasks
To configure DHCP, an administrator must first set up a DHCP server and provide it with configuration
parameters and policy information including IP address ranges, lease length specifications, and
configuration data that DHCP hosts need.
Configuring the Dell system to be a DHCP server is a three-step process:
1. Configuring the Server for Automatic Address Allocation
2. Specifying a Default Gateway
3. Enable the system to be a DHCP server (no disable command).

You must specify the IP address that the DHCP server should not assign to clients.
To exclude an address, follow this step.
• Exclude an address range from DHCP assignment. The exclusion applies to all configured pools.
