配置无线IP电话注册并排除故障

简介

本文档介绍如何配置无线IP电话注册并排除其故障到Cisco Unified Communications Manager(CUCM)。

思科无线IP电话适用于需要断开有线网络连接并保持连接的用户。

作者：Luis Segnini和Kenny Araya，思科TAC工程师。

先决条件

要求

Cisco 建议您了解以下主题：

• 无线架构
• 无线IP电话配置
• CUCM基本配置

使用的组件

• 思科统一通信管理器8.6或更高版本
• 无线IP电话型号(792X、9971、8821)

以下指南基于Cisco Unified 9971 IP电话型号。配置可能因IP电话型号而异。

本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。

配置

思科统一无线局域网控制器和接入点

无线局域网(WLAN)设置

建议为IP电话使用单独的服务集标识符(SSID)。但是，如果已配置现有SSID以支持支持语音的思科无线局域网终端，则可以改用该WLAN。

IP电话使用的SSID可配置为仅适用于特定802.11无线电类型。 

建议使IP电话在5 GHz频段上运行，因为它有许多可用信道，而且干扰源不如2.4 GHz频段。

确保所选SSID未被任何其他无线LAN使用，因为在通电或漫游期间可能导致故障；尤其是使用不同安全类型时。

为了利用思科集中密钥管理(CCKM)，请在IP电话按顺序运行固件版本9.1(1)或更高版本时启用Wi-Fi保护访问(WPA)2策略和高级加密标准(AES)加密和802.1x + CCKM，以验证密钥管理类型启用快速安全漫游。

如果IP电话运行9.1(1)之前的固件版本，则启用带临时密钥完整性协议(TKIP)加密和802.1x + CCKM的WPA策略以进行身份验证的密钥管理类型，以便启用快速安全漫游。

仅当IP电话或其他启用WMM的电话将使用此SSID时，Wi-Fi多媒体(WMM)策略才应设置为“必需”。如果WLAN中存在none-WMM客户端，建议将这些客户端放在另一个SSID/WLAN上。如果非其他WMM客户端必须使用与IP电话相同的SSID，则确保WMM策略设置为“允许”。

启用7920接入点(AP)呼叫准入控制(CAC)以向客户端通告服务质量(QoS)基本服务集(QBSS)。   

根据您的要求配置启用会话超时(Enable Session Timeout)。

建议禁用会话超时或延长超时(例如24小时/86400秒)，以避免音频呼叫期间可能发生的中断。如果禁用，则会避免完全中断，但会话超时有助于定期重新验证客户端凭据，以确保客户端使用有效凭据。

必须禁用启用Aironet扩展(Aironet IE)、点对点(P2P)阻止操作。根据需要配置客户端排除(Client Exclusion)，可以调整Off Channel Scanning Defer（关闭通道扫描延迟）以延迟某些队列的扫描以及扫描延迟时间。  

可根据需要配置每个AP无线电的最大允许客户端数。

必须禁用所需的动态主机配置协议(DHCP)地址分配。

管理帧保护必须设置为“最佳”或“禁用”。

为了获得最佳电池性能和质量，请使用2的传输流量指示消息(DTIM)周期和100毫秒的信标周期。

确保禁用客户端负载平衡和客户端频段选择。

控制器设置

确保Cisco Unified Wireless LAN控制器主机名配置正确。

如果使用思科统一无线局域网控制器上的多个端口，请启用链路聚合(LAG)。

配置所需的AP组播模式。在6.0之前的版本中，在常规控制器设置中配置了主动负载均衡。在6.0及更高版本中，这称为客户端负载均衡，可在WLAN配置（SSID设置）下配置。

802.11网络设置

如果使用5 GHz，请确保802.11a网络状态为“已启用”。 将信标周期设置为100毫秒。

确保启用动态传输功率控制(DTPC)支持。如果使用Cisco 802.11n接入点，请确保已启用ClientLink。使用当前版本，可以配置Maximum Allowed Clients。

建议将12 Mbps设置为强制（基本）速率，将18 - 24或18 - 54 Mbps设置为支持（可选）速率；但是，某些环境可能需要6 Mbps才能启用为必需（基本）。36 - 54 Mbps可以选择禁用，如果没有应用可以从这些速率（如视频）中受益。

启用CCX位置测量。

配置思科统一IP电话9971

要在IP电话上配置Wi - Fi设置，请使用键盘和触摸屏导航至应用按钮>管理员设置>网络设置> WLAN设置。

无线LAN设置

使用以下指南配置无线LAN配置文件。

• 确保无线设置为“On”。
• WLAN登录访问可设置为On，以在“应用”菜单中提供快捷访问，以更新用户名或密码。
• 输入语音无线LAN的SSID（区分大小写）。

思科统一IP电话9971支持单个无线LAN配置文件，允许单个SSID。

有三种不同的802.11模式。

• 自动
• 802.11a
• 802.11b/g

自动模式将扫描2.4和5 GHz信道，并尝试在配置的网络可用时将5 GHz信号与接入点关联。

802.11a模式将仅扫描5 GHz信道，而802.11b/g模式将仅扫描2.4 GHz信道，如果配置的网络可用，则将尝试与接入点关联。

将IP电话配置为在安全模式下使用Open with Wired Equivalent Privacy(WEP)或Shared Key，输入与接入点配置匹配的静态WEP密钥信息。

• 在IPv4 Setup（IPv4设置）中，选择是使用DHCP还是配置静态IP信息。
• 如果选项150或66未配置为通过网络的DHCP范围提供简单文件传输协议(TFTP)服务器的IP地址，则将Alternate TFTP（备用TFTP）设置为“Yes”，并输入TFTP服务器的IP地址。

配置Cisco Unified Communications Manager

步骤1.为IP电话配置正确的Phone按钮模板。

 步骤2.将IP电话添加到CUCM。

 步骤3.填写必填字段。

 步骤4.分配新创建的电话按键模板和软键模板。

 步骤5.对IP电话使用非安全配置文件。

安全配置文件可用于启用身份验证模式或加密模式，然后启用信令、媒体和配置文件加密。证书颁发机构代理功能(CAPF)必须运行，才能使用具有安全配置文件的本地签名证书(LSC)。思科统一无线IP电话7925G、7925G - E X和7926 G具有制造安装证书(MIC)，也可与安全配置文件一起使用。

确认

从IP电话收集控制台日志。我们可以看到IP电话和接入点之间交换的不同消息。

IP电话开始扫描介质以查找可用的SSID。
