DHCP Server Configuration Examples

8.Add to the host scope by specifying the NetBIOS-node-type for this particular host:

XSR(config-dhcp-host)#netbios-node-type h-node

9.Specify any numbered options. For example, setting DHCP option 28 specifies the broadcast address in use on the client's subnet:

XSR(config)#ip dhcp pool local_clients XSR(config-dhcp-pool)#option 28 ip 255.255.255.255

DHCP Server Configuration Examples

The following examples configure DHCP with different options. For DHCP implementations with firewall configured, refer to “Configuring Security on the XSR” on page 16-1.

Pool with Hybrid Servers Example

In the following example, the single DHCP pool dpool is created and two default routers defined: 168.16.22.100 (higher preference) and 168.16.22.101 (lower preference). The domain name enterasys.com is specified and a list of two DNS servers defined - 168.16.33.102 (higher) and 168.16.33.103 (lower). NetBIOS servers are specified as type hybrid - 168.16.44.103 (higher) and 168.16.44.104 (lower). Finally, the lease time for all clients is limited to 10 days.

XSR(config)#ip local pool dpool 168.16.22.0/24

XSR(config)#ip dhcp pool dpool

XSR(config-dhcp-pool)#default-router 168.16.22.100 168.16.22.101

XSR(config-dhcp-pool)#domain-name enterasys.com

XSR(config-dhcp-pool)#dns-server 168.16.33.102 168.16.33.103

XSR(config-dhcp-pool)#netbios-name-server 168.16.44.103 168.16.44.104

XSR(config-dhcp-pool)#netbios-node-type h-node

XSR(config-dhcp-pool)#lease 10

Manual Binding Example

In this example, the single DHCP pool dpool is created with a domain name enterasys.com. A host is defined with MAC address 00:f0:12:11:22:a1 in dotted decimal format and a manual binding is specified by IP address 1.1.1.20 and mask 255.255.255.0. The domain name for this host is specified as ent.com (this will override enterasys.com specified for this pool).

XSR(config)#ip local pool dpool 1.1.1.0/24

XSR(config)#ip dhcp pool dpool

XSR(config-dhcp-pool)#domain-name enterasys.com

XSR(config-dhcp-pool)#hardware-address 00f0.1211.22a1

XSR(config-dhcp-host)#host 1.1.1.20 255.255.255.0

XSR(config-dhcp-host)#domain-name ent.com

Manual Binding with Class Example

In the following example, the single DHCP pool dpool is created with the domain name enterasys.com. A class engineering is defined. The domain name for all hosts is ent.com. A host is defined with a MAC address in dotted decimal format. A manual binding is specified by IP address 1.1.1.20 and mask 255.255.255.0.
