www.qtech.ru

 Example: Specify IP address 10.1.128.160 to be bound to the user with hardware

address 00-00-e2-3a-26-04 in manual address binding.

 Switch(dhcp-1-config)#hardware-address 00-00-e2-3a-26-04

 Switch(dhcp-1-config)#host 10.1.128.160 24

 Related Command: host

1.1.13 host

 Command: host <address> [<mask> | <prefix-length>]

 no host

 Function: Specifies the IP address to be assigned to the user when binding addresses

manually; the “no host” command deletes the IP address.

 Parameters: <address> is the IP address in decimal format; <mask> is the subnet mask

in decimal format; <prefix-length> means mask is indicated by prefix. For example,

mask 255.255.255.0 in prefix is “24”, and mask 255.255.255.252 in prefix is “30”.

 Command Mode: DHCP Address Pool Mode

 Default: None

 Usage Guide: If no mask or prefix is configured when configuring the IP address, and no

information in the IP address pool indicates anything about the mask, the system will

assign a mask automatically according to the IP address class.

 This command is used with “hardware address” command or “client identifier”

command when binding addresses manually. If the identifier or hardware address of

the requesting client matches the specified identifier or hardware address, the DHCP

server assigns the IP address defined in “host” command to the client.

 Example: Specifying IP address 10.1.128.160 to be bound to user with hardware

address 00-10-5a-60-af-12 in manual address binding.

 Switch(dhcp-1-config)#hardware-address 00-10-5a-60-af-12

 Switch(dhcp-1-config)#host 10.1.128.160 24

 Related command: hardware-address, client-identifier

1.1.14 ip dhcp conflict logging

 Command: ip dhcp conflict logging

 no ip dhcp conflict logging

 Function: Enables logging for address conflicts detected by the DHCP server; the “no ip

dhcp conflict logging” command disables the logging.

 Default: Logging for address conflict is enabled by default.

 Command mode: Global Mode

 Usage Guide: When logging is enabled, once the address conflict is detected by the

DHCP server, the conflicting address will be logged. Addresses present in the log for

conflicts will not be assigned dynamically by the DHCP server until the conflicting

records are deleted.

 Example: Disable logging for DHCP server.

 Switch(config)#no ip dhcp conflict logging
