我遵循了此处列出的说明 -->https://community.polycom.com/t5/VoIP-SIP-Phones/FAQ-Utilizing-VLAN-s-with-Polycom-phones/td-p/38100.但未能如愿。
因此,我有计算机(VLAN 1),这些计算机接入 Polycom VVX 电话的底部,我希望将其分离到 VLAN 11 中。
我在 Cisco SG300-28PP 交换机上禁用了 CDP 和 LLDP。我定义了 VLAN 11,并将其作为允许的中继添加到 Cisco SG300-28PP 交换机上的所有接口。我还在 Polycom VVX 上禁用了这两个协议。我在 Polycom VVX 上启用了选项 128 的固定发现。我在 DHCP 服务器(在本例中为 Windows 2012 R2 框)上为 VLAN-A=11; 添加了选项 128。虽然计算机通过 VLAN 1 正常联网,但电话不会作为 VLAN 11 网络的一部分获取 DHCP 地址。
这两个网络从 Cisco SG300-28PP 接入 Cisco ASA 5505,一个接口用于 VLAN 1,另一个接口用于 VLAN 11。我在 Cisco ASA 5505 上设置了 DHCP 中继,以便来自 VLAN 11(10.4.4.0/24)的请求被转发到 VLAN 1(10.0.4.0/24)上的 10.0.4.5。
以下是交换机配置。以及 ASA 配置的片段和定义的 DHCP 范围的屏幕截图。您知道我可能遗漏了什么吗?

答案1
电话会在 DHCP 提供消息中查找自定义选项 (128),以了解应使用哪个 VLAN。必须在 DHCP 作用域中为本机(未标记)VLAN 配置此选项。
手机开机流程为:
- 启动并在本征 VLAN(本例中为 Vlan 1)上生成 DHCP 发现消息。
- DHCP 服务器以 DHCP 提供消息进行响应。此消息包含自定义选项 128。选项字符串包括电话应使用哪个 VLAN。(“VLAN-A=11;”)。
- 电话重新启动并在 VLAN 11 上生成 DHCP 发现消息(标记有 VID=11)。
- DHCP 服务器以来自配置的 VLAN 11 范围的报价进行响应。
- 电话使用 VLAN 11 上的地址,并继续其启动过程。
