Enterasys Networks X-PeditionTM manual Create a Corresponding Dhcp Pool, Enable the Dhcp Server

Configuration Steps

1.Add global pool local_clients including the starting IP address of the range and addresses that are unreachable to network clients:

XSR(config)#ip local pool local_clients 1.1.1.0/24 XSR(ip-local-pool)#exclude 1.1.1.249 6

Create a Corresponding DHCP Pool

2.Map this local pool to a DHCP pool by specifying the correct name:

XSR(config)#ip dhcp pool local_clients

Configure DHCP Network Parameters

3.On the pool just supplied to DHCP, define some attributes for network clients. They include the lease duration (dynamic leases) of two hours and 30 minutes, IP addresses of the default router and DNS server (these IP addresses derive from the excluded address range on the IP local pool), and the Enterasys.com domain name.

XSR(config-dhcp-pool)#lease 0 2 30 XSR(config-dhcp-pool)#default-router 1.1.1.249 1.1.1.250 XSR(config-dhcp-pool)#dns-server 1.1.1.254 XSR(config-dhcp-pool)#domain-name ets.enterasys.com

Note: Some values can also be configured for a Client-Class or Host scope.

Enable the DHCP Server

4.Initialize the DHCP Server on FastEthernet interface 2:

XSR(config)#interface fastethernet 2 XSR(config-if<F2>#ip dhcp server

Optional: Set Up a DHCP Nested Scope

5.Continue configuring local_clients by creating a named client-class and using it to override the lease time. Clients presenting this name in DHCP messages will get the shorter lease time but will continue to receive dns-serverand other values defined in the pool.

XSR(config)#ip dhcp pool local_clients XSR(config-dhcp-pool)#client-class class1 XSR(config-dhcp-class)#lease 0 0 30

6.Extend the client-class attributes to include the address of a NetBIOS-name-server:

XSR(config-dhcp-class)#netbios-name-server 1.1.1.253

Optional: Configure a DHCP Manual Binding

7.Add a manual binding in the local_client pool:

XSR(config-dhcp-class)#host 1.1.1.7 255.255.255.0 XSR(config-dhcp-host)#hardware-address 1111.2222.3333 1
