Host address mask no host | Microsoft ES4625, ES4649 manual

4 Command Line Interface

Command Modes

DHCP Pool Configuration

Example

The following example leases an address to clients using this pool for 7 days.

Console(config-dhcp)#lease 7

Console(config-dhcp)#

host

Use this command to specify the IP address and network mask to manually bind to a DHCP client. Use the no form to remove the IP address for the client.

Syntax

host address [mask] no host

•address - Specifies the IP address of a client.

•mask - Specifies the network mask of the client.

Default Setting

None

Command Mode

DHCP Pool Configuration

Usage Guidelines

•Host addresses must fall within the range specified for an existing network pool.

•When a client request is received, the switch first checks for a network address pool matching the gateway where the request originated (i.e., if the request was forwarded by a relay server). If there is no gateway in the client request (i.e., the request was not forwarded by a relay server), the switch searches for a network pool matching the interface through which the client request was received. It then searches for a manually configured host address that falls within the matching network pool.

•When searching for a manual binding, the switch compares the client identifier for DHCP clients, and then compares the hardware address for DHCP or BOOTP clients.

•If no manual binding has been specified for a host entry with the client-identifier or hardware-address commands, then the switch will assign an address from the matching network pool.

•If the mask is unspecified, DHCP examines its address pools. If no mask is found in the pool database, the Class A, B, or C natural mask is used (see page 3-227). This command is valid for manual bindings only.

•The no host command only clears the address from the DHCP server database. It does not cancel the IP address currently in use by the host.
