Multicast traffic management involves controlling the flow of multicast traffic within a network to optimize its performance and ensure that it reaches its intended destinations. Cisco Catalyst 3850 4X1GE Expansion Module (C3850-NM-4-1G) is a network expansion module that can be installed in the Cisco Catalyst 3850 series switches to increase their port capacity and enhance their capabilities.
Multicast Traffic Management
The C3850-NM-4-1G expansion module has four 1 Gigabit Ethernet (GE) ports, which can be used to connect devices and network segments to the switch. These ports can also be used to manage multicast traffic by configuring various multicast features and settings in the switch.
Some of the multicast features that can be configured on the Cisco Catalyst 3850 switch include:
- IGMP snooping: This feature allows the switch to listen in on IGMP messages exchanged between multicast routers and hosts. By doing so, the switch can determine which ports need to receive multicast traffic and which can be pruned to optimize bandwidth usage.
- PIM snooping: This feature allows the switch to snoop on Protocol Independent Multicast (PIM) messages exchanged between multicast routers. By doing so, the switch can determine which multicast streams need to be forwarded to which ports and can prune unnecessary streams to conserve bandwidth.
- IGMP filtering: This feature allows the switch to filter out unwanted multicast traffic by blocking IGMP messages from specific hosts or groups. This can help to reduce network congestion and improve performance.
- Multicast VLAN registration: This feature allows the switch to register multicast groups with specific VLANs. By doing so, the switch can limit the scope of multicast traffic to specific VLANs and reduce the amount of traffic that needs to be forwarded.
