Configure IGMP Snooping Globally
You can configure the parameters for IGMP snooping, which is used to build forwarding lists
for multicast traffic.
 To configure IGMP snooping globally:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see Access the Switch on page 13.
The login window opens.
4. Enter the switch’s password in the password field.
The default password is password. If you added the switch to a network on the Insight
app before and you did not yet change the password through the local browser interface,
enter your Insight network password.
The System Information page displays.
5. Select Switchingï€ > Multicast > IGMP Snooping > IGMP Snooping Configuration.
The IGMP Snooping Configuration page displays.
6. Select the IGMP Snooping Status Enable or Disable radio button.
This specifies whether IGMP snooping is enabled for the switch. The default is Enable.
7. Select the Validate IGMP IP header Enable or Disable radio button.
When IGMP IP header validation is enabled, any IGMP IP header must include the
Router Alert, ToS, and TTL information. Otherwise, the IGMP packet is discarded. The
default value is Enable.
8. Click the Apply button.
Your settings are saved.
9. To refresh the page with the latest information about the switch, click the Refresh button.
