What is wireless multicasting?

What is wireless multicasting?

Multicast transmission is a one-to-many broadcast methodology in which a WLAN AP forwards all broadcast packets from a multicast server source to a client subnet where multiple client devices are listening. The multicast server sends out a single stream during the transmission, allowing multiple clients to listen in.

What is wireless multicast forwarding?

The Wireless Multicast Forwarding provides an efficient way to forward the multicast traffic on the wireless medium and over comes the multicast transmission issues on WLAN using the repeated unicast of multicast frames. The multicast streaming server can be attached to any of the LAN ports.

How do I manually add AP to WLC?

Manually Configure Lightweight AP to join WLC

1. Configure a temporary WLC with the same name and IP Address of the WLC I want my APs to join.
2. Utilise DHCP Option 43 to ensure a cross-subnet discovery is available.
3. Manually set the Controller IP address via the CLI.

What is multicast IP address?

IP multicast is a method of sending Internet Protocol (IP) datagrams to a group of interested receivers in a single transmission. It is the IP-specific form of multicast and is used for streaming media and other network applications. It uses specially reserved multicast address blocks in IPv4 and IPv6.

What IP address range should I use when configuring multicast groups?

The Cisco Wireless network solution uses some IP address ranges for specific purposes, and you should keep these ranges in mind when configuring a multicast group: 224.0.0.0 through 224.0.0.255—Reserved link local addresses 224.0.1.0 through 238.255.255.255—Globally scoped addresses 239.0.0.0 through 239.255.x.y /16—Limited scope addresses

How do I use multicast on my wireless LAN controller?

Multicast in Wireless LAN Controllers (WLCs) If your network supports packet multicasting, you can configure the multicast method that the controller uses in order to transport the multicast packets over CAPWAP to all or several access points at the same time.

Can I use the CAPWAP multicast group address on a WLC?

Cisco recommends that any multicast applications on your network not use the multicast address configured as the CAPWAP multicast group address on the controller. For multicast to work on Cisco 2504 WLC, you have to configure the multicast IP address. Multicast mode is not supported on Cisco Flex 7500 Series WLCs.

How does a WLC perform multicast?

Cisco Wireless LAN controllers (WLC) perform multicast in two methods. 1. Unicast Mode (WLC unicast every multicast packet to every access point associated to the controller). This mode is inefficient, but if your network does not support multicast, this is the only mode you can use.
