Netgear XCM8810 - 8800 SERIES 10-SLOT CHASSIS SWITCH ユーザーズマニュアル

Output from this command also lists the aging time of the port.

DHCP Server

XCM8800 has Dynamic Host Configuration Protocol (DHCP) support. In simple terms, a 
DHCP server dynamically manages and allocates IP addresses to clients. When a client 
accesses the network, the DHCP server provides an IP address to that client. The client is 
not required to receive the same IP address each time it accesses the network. A DHCP 
server with limited configuration capabilities is included in the switch to provide IP addresses 
to clients.

This section describes the following topics:

•     Enabling and Disabling DHCP 

•     Configuring the DHCP Server 

•     Displaying DHCP Information 

Enabling and Disabling DHCP

DHCP is enabled on a per port, per VLAN basis. To enable or disable DHCP on a port in a 
VLAN, use one of the following commands:

enable dhcp ports <portlist> vlan <vlan_name>

 

disable dhcp ports <portlist> vlan <vlan_name>

 

Configuring the DHCP Server

The following commands allow you to configure the DHCP server included in the switch. The 
parameters available to configure include the IP address range, IP address lease, and 
multiple DHCP options.

To configure the range of IP addresses assigned by the DHCP server, use the following 
command:

configure vlan <vlan_name> dhcp-address-range <ipaddress1> - <ipaddress2>

 

To remove the address range information, use the following command:

unconfigure vlan <vlan_name> dhcp-address-range

 

To set how long the IP address lease assigned by the server exists, use the following 
command:

configure vlan <vlan_name> dhcp-lease-timer <lease-timer>

 

To set the default gateway, Domain Name Servers (DNS) addresses, or Windows Internet 
Naming Service (WINS) server, use the following command:

configure {vlan} <vlan_name> dhcp-options [default-gateway | dns-server 

{primary | secondary} | wins-server] <ipaddress>
