DHCP Server Commands

Dynamic Host Configuration Protocol (DHCP) server commands are used to enable or disable the DHCP server, and create or delete a DHCP pool.

Table C-9. DHCP Server Commands (1 of 3)

[no] service dhcp

Minimum Access Level: Administrator

Command Mode: config

Allows you to enable or disable the DHCP server. The DHCP server is enabled by default but is not active until other DHCP server options are configured. When an IP address is assigned to a host by the DHCP Server and there is no matching routing table entry, a host entry for that IP address is created. This entry is deleted from the routing table when the lease expires or the IP address is relinquished.

When an IP address is assigned to a host on the local Ethernet by the DHCP Server, an ARP table entry is created mapping that IP address to the corresponding host MAC address. This entry is deleted from the ARP table when the lease expires or the IP address is relinquished. This entry is not deleted according to the timeout mechanism that applies to normal ARP entries.

NOTE: The DHCP Relay and DHCP Server cannot be enabled at the same time.

[no] ip dhcp pool pool-name

Minimum Access Level: Administrator

Command Mode: config

Allows you to create or delete a DHCP pool and places it in DHCP pool configuration mode to configure IP DHCP pool parameters. All commands entered while in DHCP pool configuration mode are applied to the specified DHCP pool. No DHCP pools are configured by default.

Minimum Access Level: Administrator

The no ip dhcp excluded-addresscommand allows you to release previously excluded IP addresses for distribution to clients. No IP addresses are excluded by default.
