7.3.2 Configuration Scheme
After the channel is changed, the client (Host B) still receives irrelevant multicast data,
the data from the previous channel and possibly other unknown multicast data, which
increases the network load and results in network congestion.
To avoid Host B from receiving irrelevant multicast data, you can enable Fast Leave on
port 1/0/2 and configure the switch to discard unknown multicast data. To change channel,
Host B sends a leave message about leaving the previous channel. With Fast Leave
enabled on port 1/0/2, the switch will then drop multicast data from the previous channel,
which ensures that Host B only receives multicast data from the new channel and that the
multicast network is unimpeded.
Demonstrated with T2600G-28TS, this section provides configuration procedures in two
ways: using the GUI and using the CLI.
7.3.3 Using the GUI
1) Create VLAN 10. Add port 1/0/2 to the VLAN as untagged port and port 1/0/4 as tagged
port. Configure the PVID of the two ports as 10. For details, refer to Configuring 802.1Q
VLAN.
2) Choose the menu L2 FEATURES > Multicast > IGMP Snooping > Global Config to load
the following page. In the Global Config section, enable IGMP Snooping globally and
configure Unknown Multicast Groups as Discard.
