D-Link DES-3552 [127/260] Dhcp bootp relay

DES-3550 Fast Ethernet Layer 2 Switch

To configure Limited IP Multicast Range:

Choose the port or sequential range of ports using the From…To… port pull-down menus.

Use the remaining pull-down menus to configure the parameters described below:

Parameter Description

State

Toggle the State field to either Enabled or Disabled a given port or group of

ports where access is to be either permitted or denied.

From Multicast IP

Enter the lowest multicast IP address of the range.

To Multicast IP

Enter the highest multicast IP address of the range.

Access

Toggle the Access field to either Permit or Deny to limit or grant access to a

specified range of Multicast addresses on a particular port or range of ports.

Click Apply to implement the new settings on the Switch.

DHCP/BOOTP Relay

The Switch can setup as a DHCP relay agent. A DHCP relay agent extends the reach of a DHCP server so that it is not

necessary to use multiple DHCP servers to accommodate multiple IP subnets. As a relay agent, the Switch does not manage

IP addresses. It relays DHCP requests on behalf of clients located on a local subnet to a remote or centralized DHCP server.

An additional feature has been created to further aid in local management of the IP addresses. Option 82 is used by the relay

agent to insert additional information into the client’s DHCP request. This information can be used to implement policies

intended to improve security and efficiency.

For simplicity, references to DHCP include BOOTP, i.e. DHCP requests are treated identically to BOOTP requests for the

DHCP relay agent.

DHCP / BOOTP Relay Global Settings
