Act as IGMP
Querier²
Disabled If enabled, the switch can serve as the “querier,” which is
responsible for asking hosts if they want to receive multicast
traffic.
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.
Parameter Description
Subnet
Configuration
IP Subnet Configuration Specifies the IP interface for VLANs
configured on this switch, including the subnet
address and routing protocols.
Port Group Configuration See “VLAN Table Configuration” on chapter 3.
Protocol
Configuration
Configures ARP timeout, enables Proxy ARP, sets the preferred servers
for BOOTP / DHCP Relay, as well as enabling / configuring unicast and
multicast protocols globally for this switch.
Stati c ARP
Configuration
Used to map an IP address to a specific physical MAC address.
Static Route Used to configure static routes to other IP networks, subnetworks, or
hosts.
Default
Route
Defines the router to which this switch will forward all traffic for unknown
networks.

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.
