[海康]视频监控环境中配置组播模式

在视频监控的环境中，一共有19个海康威视的网络摄像头，作为组播源，所有的摄像头配置在vlan252中，核心交换机为一台Cisco3560交换机，在交换机上启用组播，监控的客户端采用组播的方式，分别在vlan254和vlan301中，采用稀疏模式，实现如下。

在3560上启用组播

(config)# ip multicast-routing distributed

在相应的接口上配置pim-sm

(config)#int vlan 252

(config-if)# ip pim sparse-mode

(config-if)#int vlan 254

(config-if)#ip pim sparse-mode

(config-if)#int vlan 301

(config-if)#ip pim sparse-mode

配置静态rp

(config)# ip pim rp-address 192.168.16.65

交换机上的配置完成。

在摄像头上配置各个摄像头的组播地址，每个摄像头作为组播源，组播地址从239.252.0.2~239.252.0.20。

在海康威视的客户端软件上配置相应的协议，客户端的软件版本是免费的iVMS-4200。

首先在该软件的设备管理中，将每个设备的连接设置中填入各个设备的多播地址；

然后在监控点配置中，选择“网络设置”，将协议类型由默认的“TCP”改为“MCAST”，设置完成。

打开预览，各个摄像头的监控画面都能够正常显示。

在3560上查看组播路由表：

#sh ip mroute
