在 Packet Tracer 中将 IPPhone 添加到 VLAN 的问题

网络工程 VLAN 网络电话

2021-07-12 21:34:06

我正在尝试在 VLAN 中添加两个 IPPHONE，但它似乎不起作用，因为电话没有收到它们的 IP 地址。我有一个路由器通过交换机，然后电话连接到交换机。我正在关注这个https://edsonvuma.wordpress.com/2013/06/10/configuring-voip-basic-level_packet-tracer/教程。

添加这些电话的最佳或最常用方法是什么？这是我的三个交换机配置和我的图表

首先，你需要IP routing在你的 Lan-Switch1 上启用，我在你的配置中没有看到，然后验证以下几点：

您可以从 Lan-Switch1 上的 Int VLAN 12 访问/ping DHCP 服务器 (192.168.10.254)。
所有网络设备上都配置了 VLAN 12。
DHCP 服务已开启，并且 IP 电话的 DHCP 范围已在 DHCP 服务器 (192.168.10.254) 上正确配置。
在 Lan-Switch1 上配置语音端口并通过将其连接到此端口来测试您的 IP 电话：

更新的答案：

下面是我的设置。IP_Phone 和 PC（在 Switch1 的 VLAN 12 中）都可以从 DHCP 服务器获取 IP 地址：
