Configuration
Characteristics of Bootp and DHCP. The Bootp protocol is designed for
a network in which each host has a permanent network location. It is not
adaptable to a mobile computing environment.
The Dynamic Host Configuration Protocol (DHCP) manages the allocation
of TCP/IP configuration information by automatically assigning IP
addresses.When a device connects to the network, it requests an address
from the DHCP server. In dynamic mode, the address is used by the device
for a specified period of time. The time period depends on the situation; one
device may only need the address for an hour, while another device may use
the same address for several days. DHCP is more suitable in environments
where the number of IP addresses needed exceeds the number available. It
also allows a device to obtain its configuration information, such as the IP
Address and Subnet Mask, in one message, reducing the demand on the
network.
A static IP address is a unique address that is assigned to one client only.
Static addresses are used for an extended time period.
Configuration - Port Configuration
The Port Configuration page displays information about the switch ports.
The settings are explained in the following table. To modify a port setting,
click on a port then select the Modify Selected Ports button. Modify
multiple ports at one time by using Ctrl-Click to select the desired ports.
Note: Some switches support trunking. For information on trunking,
see the online help for that device.
