Administrator Guide

Switch Management Commands 1927
• Client address lease time – lease
Administrators may also configure manual bindings for clients using the host
command in DHCP Pool Configuration mode. This is the most often used
for DHCP clients for which the administrator wishes to reserve an ip address,
for example a computer server or a printer. A DHCP pool can contain
automatic or dynamic address assignments or a single static address
assignment.
To configure a manual address binding, configure the pool properties using
the DHCP pool commands listed below. It is only necessary to configure a
DHCP client identifier or a BOOTP client MAC address for a manual
binding. To configure a manual binding, the client identifier or hardware
address must be specified before specifying the host address.
• DHCP client identifier – client-identifier
• BOOTP client MAC address – hardware-address
• Host address – host
• Client name (optional) – client-name
