ip dhcp excluded-address

To create an excluded pool and to prevent DHCP server from assigning certain addresses to DHCP clients, use the command ip dhcp excluded-address in Global Configuration Mode. The no form of the command deletes the created excluded pool. This command is a complete standardized implementation of the existing command and operates similar to that of the command excluded-address. This command is used to exclude a single IP address or a range of IP addresses.

ip dhcp excluded-address

ip dhcp excluded-address { <low-address> } { <high-address> }

ip dhcp excluded-address

no ip dhcp excluded-address { <low-address> } { <high-address> }

Parameters

Parameter	Type	Description
<low-address>	Integer	Enter to set the start IP address for an excluded pool. This address denotes the first IP address of a range of IP addresses which needs to be excluded from the created subnet pool. This IP address should be: lower than the end IP address, and in the same network of the subnet pool’s start IP address.
`<high-address>`		Enter to set the end IP address for an excluded pool. This address denotes the last IP address of a range of IP addresses which needs to be excluded from the created subnet pool. This IP address should be: high than the start IP address, and within or equal to the subnet pool’s end IP address

Mode

Global Configuration Mode

Prerequisites

Subnet pool should have been created before creating an excluded pool. This excluded pool should be within the range of the created subnet pool.
For example, the excluded pool 20.0.0.20 – 20.0.0.30 created using this command is within the already created subnet pool 20.0.0.0 – 20.0.0.100.

Examples

iS5Comm(config)# ip dhcp excluded-address 20.0.0.20 20.0.0.30
