6: Basic Parameters DHCP On models with an Ethernet Switch installed, the console manager can provide DHCP services to clients connected to the Ethernet Switch. By default DHCP is disabled. Two DHCP modes are supported:  DHCP Server: provides IP addresses and other networking parameters to devices connected to the Ethernet Switch that are running DHCP clients. The server can provide IP address, subnet mask, primary DNS IP address, secondary DNS IP address, gateway and domain. Lease times are given in hours, up to a maximum of 14 days.  DHCP Relay: forwards DHCP packets between devices connected to the Ethernet Switch and DHCP servers that are accessible via one of the other interfaces (Eth1, Eth2, cellular, or WiFi). This allows hosts connected to the Ethernet Switch to acquire IP addresses from a DHCP server already in service and reachable on the network. Because DHCP is a broadcast-based protocol, by default its packets do not pass from devices connected to the Ethernet Switch to other subnets. A DHCP relay agent receives any DHCP broadcasts on the Ethernet Switch and forwards them via unicast to DHCP servers on a different subnet. Since the DHCP servers are located on a different subnet they may need routes back to the Ethernet Switch that is requesting DHCP addresses on behalf of its connected clients. DHCP Relay can be configured to use one or two DHCP servers. To configure DHCP: 1. Click the Network tab and select the DHCP option. The Network > DHCP page displays.

SLC™ 8000 Advanced Console Manager User Guide

DHCP

On models with an Ethernet Switch installed, the console manager can provide DHCP services to

clients connected to the Ethernet Switch. By default DHCP is disabled. Two DHCP modes are

supported:



DHCP Server:

provides IP addresses and other networking parameters to devices connected

to the Ethernet Switch that are running DHCP clients. The server can provide IP address,

subnet mask, primary DNS IP address, secondary DNS IP address, gateway and domain.

Lease times are given in hours, up to a maximum of 14 days.



DHCP Relay:

forwards DHCP packets between devices connected to the Ethernet Switch and

DHCP servers that are accessible via one of the other interfaces (Eth1, Eth2, cellular, or WiFi).

This allows hosts connected to the Ethernet Switch to acquire IP addresses from a DHCP

server already in service and reachable on the network. Because DHCP is a broadcast-based

protocol, by default its packets do not pass from devices connected to the Ethernet Switch to

other subnets. A DHCP relay agent receives any DHCP broadcasts on the Ethernet Switch

and forwards them via unicast to DHCP servers on a different subnet. Since the DHCP

servers are located on a different subnet they may need routes back to the Ethernet Switch

that is requesting DHCP addresses on behalf of its connected clients. DHCP Relay can be

configured to use one or two DHCP servers.

To configure DHCP:

Click the

Network

tab and select the

DHCP

option. The Network > DHCP page displays.
