ticast-group by sending a join request message towards the network router, and responds to que-
ries sent from the network router by dispatching a join report.
A given port can be either manually configured to be a router-port or it can be dynamically man-
ifested when having received a query, hence, the network router is connected to this port. All
IGMP Snooping Control packets received from hosts (joins / leaves) are forwarded to the router-
port, and the router-port will update its multicast-group data-base accordingly. Each dynamically
learnt multicast group will be added to all of the router-ports on the switch.
As many as 5K multicast groups can be created on the switch.
5.6.1 Configuring IGMP Snooping
You can configure IGMP snooping to establish multicast group memberships.
 To configure IGMP snooping:
Step 1. Log in as admin.
Step 2. Enter config mode. Run:
Step 3. Enable IGMP snooping globally. Run:
Step 4. Enable IGMP snooping on a VLAN. Run:
5.6.2 Defining a Multicast Router Port on a VLAN
You can define a Multicast Router (MRouter) port on a VLAN in one of the following methods:
 To change the Interface Switchport to Trunk:
Step 1. Log in as admin.
Step 2. Enter config mode. Run:
Step 3. Enable IGMP snooping globally. Run:
Step 4. Change the interface switchport mode of the port (the interface is member of VLAN 1 by
default). Run:
Step 5. Change back to config mode. Run:
switch > enable
switch # configure terminal
switch (config) # ip igmp snooping
switch (config) #
switch (config) # vlan 2
switch (config vlan 2) # ip igmp snooping
switch > enable
switch # configure terminal
switch (config) # ip igmp snooping
switch (config) #
switch (config) # interface ethernet 1/1
switch (config interface ethernet 1/1) # switchport mode trunk
switch (config interface ethernet 1/1) # exit
switch (config) #
