2-11.2 MLD Snooping
Curiously enough, a network node that acts as a source of IPv6 multicast traffic is only an
indirect participant in MLD snooping—it just provides multicast traffic, and MLD doesn't
interact with it. (Note, however, that in an application like desktop conferencing a network node
may act as both a source and an MLD host; but MLD interacts with that node only in its role as
an MLD host.)
A source node creates multicast traffic by sending packets to a multicast address. In IPv6,
addresses with the first eight bits set (that is, "FF" as the first two characters of the address)
are multicast addresses, and any node that listens to such an address will receive the traffic
sent to that address. Application software running on the source and destination systems
cooperates to determine what multicast address to use. (Note that this is a function of the
application software, not of MLD.)
When MLD snooping is enabled on a VLAN, the switch acts to minimize unnecessary multicast
traffic. If the switch receives multicast traffic destined for a given multicast address, it forwards
that traffic only to ports on the VLAN that have MLD hosts for that address. It drops that traffic
for ports on the VLAN that have no MLD hosts
2-11.2.1 Basic Configuration
The section will let you understand how to configure the MLD Snooping basic configuration
and the parameters .
Web Interface
To configure the MLD Snooping Configuration in the web interface:
1. Click Configuration, MLD Snooping, Basic Configuration
2. Evoke to enable or disable the Global configuration parameters. Evoke the port to join
Router port and Fast Leave.
3. Scroll to select the Throtting mode with unlimited or 1 to 10
4. Click the save to save the setting
5. If you want to cancel the setting then you need to click the Reset button. It will revert to
