CONFIGURING THE SWITCH

CLI – This example changes the DSCP priority for packets matching an IP ACL rule, and the 802.1p priority for packets matching a MAC ACL rule.

Console(config)#interface ethernet 1/13-1Console(config-if)#match access-list ip bill set dscp 03-130Console(config-if)#match access-list mac mike set priority 03-145Console(config-if)#end

Console#show marking3-131Interface ethernet 1/1

match access-list IP bill set DSCP 0 match access-list MAC a set priority 0 Console#

Multicast Filtering

Multicasting is used to support real-time applications such as videoconferencing or streaming audio. A multicast server does not have to establish a separate connection with each client. It merely broadcasts its service to the network, and any hosts that want to receive the multicast register with their local multicast switch/router. Although this approach reduces the network overhead required by a multicast server, the broadcast traffic must be carefully pruned at every multicast switch/router it passes through to ensure that traffic is only passed on to the hosts which subscribed to this service.

Unicast Flow

Multicast Flow

This switch uses IGMP (Internet Group Management Protocol) to query for any attached hosts that want to receive a specific multicast service. It identifies the ports containing hosts requesting to join the service and sends data out to those ports only. It then propagates the service request up to any neighboring multicast switch/router to ensure that it will
