Estou tentando configurar o Servidor DHCP em um switch Cisco 2960-X para obter a alocação de endereços baseada em porta. Eu gostaria que o endereço IP atribuído a qualquer dispositivo conectado a essa porta fosse sempre o mesmo.
Eu usei o seguinte guia para conseguir isso: Configurando os recursos do DHCP e o IP Source Guard
Os comandos usados são explicados em detalhes aqui: Referência de comandos dos serviços de endereçamento IP do Cisco IOS
Eu também tentei várias iterações do seguinte comando para encontrar algo que funcione: endereço ip-address client-id string [ascii]
O que eu não tenho certeza é a string após o ID do cliente. Tem que corresponder ao nome da sua interface? Se não, como o servidor DHCP sabe qual interface deve relacionar o endereço IP atribuído.
Aqui está o meu running-config:
