Opções DHCP Server Cisco

Algumas opções de configuração de DHCP em equipamentos Cisco:

Criando um escopo:
SW(config)#ip dhcp pool nome-pool
SW(dhcp-config)#network 192.168.0.0 255.255.255.0
SW(dhcp-config)#default-router 192.168.0.1
SW(dhcp-config)#dns-server 192.168.0.1
SW(dhcp-config)#exit

Entrada estática:
Mac address 00.1b.fc.ad.02.88
SW(dhcp-config)#client-identifier 0100.1bfc.ad02.88 #Adcione 01, é o que identifica ethernet
SW(dhcp-config)#host 192.168.0.69
SW(dhcp-config)#default-router 192.168.0.1
SW(dhcp-config)#dns-server 192.168.0.1
SW(dhcp-config)#exit
