Admin PC's

• IP Address: Enter IP address for the VLAN.

• Subnet Mask: Enter Subnet Mask address for the VLAN.

• NAT Domain: Set NAT Domain to private or public.

• IGMP Snooping: IGMP Snooping: Internet Group Management

Protocol (IGMP) snooping is a method by which Layer 2 devices can

“listen in” on IGMP conversations between hosts and routers. When

a switch hears a group join message from a host, it notes which switch

interface it heard the message on, and adds that interface to the group.

Similarly, when a Layer 2 switch hears a group leave message or a

response timer expires, the switch will remove that host’s switch

interface from the group.

• IGMP Querier: IGMP Querier: if the IGMP Querier is enabled, then

the router will periodically query all multicast group members on the

specified VLAN.
