Accessing Hub Features

Configuring Your Device

■Disabled—IP is disabled, there is no access to management or telnet. Not Recommended.

■Use Bootp—The Bootp protocol sets the IP address automatically.

Hub IP Configuration

If you select Manual, you must then enter an IP Address, Subnet Mask, Default Gateway, and Time to Live for the device. If you select Bootp/DHCP, the IP address will be assigned automatically.

Switching Hub IP Configuration

For the switching hubs, you must select a segment to configure before you select Manual or Bootp/DHCP. If you select Manual, you must then enter an IP Address, Subnet Mask, Default Gateway, and Time to Live for the device. If you select Bootp/DHCP, the IP address will be assigned automatically.

Characteristics of Bootp and DCHP. The Bootp protocol is designed for a network in which each host has a permanent network connection. 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.
