Internet Group Management Protocol (IGMP) snooping
Internet Group Management Protocol (IGMP) snooping is a feature that allows a switch to forward
multicast traffic intelligently on the switch. Multicast IP traffic is traffic destined to a host group.
Host groups are identified by class D IP addresses, which range from 224.0.0.0 to 239.255.255.255.
Based on the IGMP query and report messages, the switch forwards traffic only to the ports that
request the multicast traffic. This prevents the switch from broadcasting the traffic to all ports and
possibly affecting network performance.
Note that the IP address range 224.0.0.1 through 224.0.0.255 is reserved for routing protocols and
other low-level topology discovery or maintenance protocols. For example, the address 224.0.0.1 is
the “all hosts” address, and 224.0.0.2 indicates all routers on this subnet. Also, only the least
significant 23 bits of the IP address are mapped to MAC addresses, so, for example, 225.0.0.123 and
239.128.0.123 and similar IP multicast addresses all map to MAC address 01-00-5E-00-00-7B (for
Ethernet). Therefore, a switch using IGMP Snooping may collapse IP multicast group memberships
into a single Ethernet multicast group.
A traditional Ethernet network may be physically separated into different network segments to
prevent overload of the shared media. Bridges and switches connect these segments. When a packet
with a broadcast or multicast destination address is received, the switch will forward a copy into
each of the remaining network segments in accordance with IEEE 802.1D. Eventually, the packet is
made accessible to all nodes connected to the network.
This approach works well for broadcast packets that are intended to be seen or processed by all
connected nodes. In the case of multicast packets, however, this approach can lead to less efficient
use of network bandwidth, particularly when the packet is intended for only a small number of
nodes. Packets will be flooded onto network segments where no node has any interest in receiving
the packet. The problem of wasting bandwidth is even worse when the LAN segment is not shared,
for example in full duplex links.
Allowing switches to snoop IGMP packets is one way to solve this problem. The switch uses the
information in the IGMP packets as they are being forwarded throughout the network to determine
which segments should receive packets directed to particular group addresses.
Group addresses are stored in the Multicast Forwarding Database (MFDB). An IGMP address will
be removed from the database if a report for it is not received within the query interval. An interface
may be removed from an IGMP group in response to an IGMP Leave Group message.
Link aggregation (LAG)
The Intel® Blade Server Ethernet Switch Module IXM5414E supports Link Aggregation (LAG), or
port trunking. Port trunks (aggregated ports) can be used to increase the bandwidth of a network
connection or to ensure fault recovery.You can configure up to two trunk connections (combining
two to four ports into one fat pipe) between any two SB-HEs or other Layer 2 switches. However,
before making any physical connections between devices, use the Link Aggregation commands to
specify the ports that will belong to the trunking group on both switches.
When using a port trunk, note that:
• The ports used in a trunk must all be of the same speed (100 Mbps or 1000 Mbps) and operate in
full-duplex mode only.
