1.This item is only displayed for Layer 2 mode. For multilayer mode, the full IGMP protocol set is automatically enabled / disabled along with DVMRP. (See IGMP on chapter 4. See DVMRP on chapter 3 “Configuring DVMRP” and chapter 4 “DVMRP Routing Protocol”.)
2.This item is only displayed for Layer 2 mode. When IGMP is enabled for multilayer mode, the switch will always serve as the querier if elected.
3.6.6.Configuring IP Settings
If this switch is set to multilayer mode (chapter 2 “Setting the System Operation Mode”), the IP Menu will be displayed. Use this menu to configure the IP subnets for each VLAN on your switch, the unicast and multicast routing protocols, static ARP entries, static IP routes, and the default IP route.

3.6.6.1.Subnet Configuration
Use this menu to specify an IP interface for any VLAN configured on this switch that needs to communicate with a device outside of its own group (that is, another network segment). You also need to define a VLAN for each IP subnet connected directly to this switch. Note that you must first create a VLAN as described under “Configuring Virtual LANs” on chapter 3 before configuring the corresponding subnet.
