Manage IGMPv3 IP header validation
You can enable IGMPv3 IP header validation so that the switch inspects whether IGMPv3
packets conform to the IGMPv3 standard. By default, IGMPv3 IP header validation is
disabled. If IGMPv3 IP header validation is enabled, IGMPv3 messages must include a
time-to-live (TTL) value of 1 and a type of service (ToS) byte of 0xC0 (Internetwork
Control). In addition, the router alert IP option (9404) must be set.
Note: If IGMPv3 IP header validation is enabled, the switch does not drop IGMPv1 and
IGMPv2 traffic, but processes this traffic normally.
To manage IGMPv3 IP header validation:
1.
Open a web browser from a computer that is connected to the same network as the
switch, or connected directly to the switch through an Ethernet cable.
2. Enter the IP address that is assigned to the switch.
A login window opens.
3. Enter the device management password.
The password is the one that you specified the first time that you logged in. The
password is case-sensitive.
The HOME page displays.
4.
From the menu at the top of the page, select SWITCHING > QOS .
The Quality of Service (QoS) page displays.
5.
From the menu on the left, select MULTICAST.
The MULTICAST page displays.
6. Enable or disable IGMPv3 IP header validation by clicking the button in the Validate
IGMPv3 IP Header section.
When IGMPv3 IP header validation is enabled, the button bar displays green.
7. Click the APPLY button.
Your settings are saved.
