Belajar Mengkonfigurasi Cisco IOS DHCP Server Langkah-langkahnya adalah sebagai berikut: ----------------------------------------------- 1.Tentukan dan konfigurasi pool dari DHCP Server -DHPC pool name iwing-pool -Network 192.168.10.0/24 -default-router 192.168.10.1 -Domain Name iwing.org -lease time is 1 day, 5 hours, and 36 minutes ----------------------------------------------- cnc1(config)#ip dhcp pool iwing-pool cnc1(dhcp-config)#network 192.168.10.0 255.255.255.0 cnc1(dhcp-config)#default-router 192.168.10.1 cnc1(dhcp-config)#domain-name iwing.org cnc1(dhcp-config)#lease 1 5 36 cnc1(dhcp-config)# ----------------------------------------------- 2. Jika kita tidak ingin DHCP Offers memberikan Range IP address tertentu, kita bisa menggunakan perintah ip dhcp exclude [low ip add][high ip address] ----------------------------------------------- cnc1(config)#ip dhcp excluded-address 192.168.10.1 192.168.10.100 ----------------------------------------------- 3.How To check 1 ----------------------------------------------- cnc1#show ip dhcp ? binding DHCP address bindings conflict DHCP address conflicts database DHCP database agents import Show Imported Parameters pool DHCP pools information relay Miscellaneous DHCP relay information server Miscellaneous DHCP server information cnc1#show ip dhcp binding Bindings from all pools not associated with VRF: IP address Client-ID/ Lease expiration Type Hardware address/ User name 192.168.10.101 0102.004c.4f4f.50 Apr 17 2010 08:37 PM Automatic cnc1#show ip dhcp pool Pool iwing-pool : Utilization mark (high/low) : 100 / 0 Subnet size (first/next) : 0 / 0 Total addresses : 254 Leased addresses : 1 Pending event : none 1 subnet is currently in the pool : Current index IP address range Leased addresses 192.168.10.102 192.168.10.1 - 192.168.10.254 1 cnc1# ----------------------------------------------- 3.How To check 2 (gunakan perintah debug) ----------------------------------------------- cnc1#debug ip dhcp server events DHCP server event debugging is on. cnc1#debug ip dhcp server packet DHCP server packet debugging is on. ----------------------------------------------- 4. Di client (wind** xp) ketikan ipconfig /renew, IP address yang disewa, range dari 101-254 ----------------------------------------------- C:\>ipconfig /renew Windows IP Configuration Ethernet adapter
