Netgear GSM7248R Layer 3 Switches - Routing VLANs with shared access to the In - Page 2

VLAN-Definition VLANs are logical subgroups within a Local Area Network (LAN), which combine user stations, and network devices into a single unit, regardless of the physical LAN segment to which they are attached. VLANs allow network traffic to flow more efficiently within subgroups. VLANs use software to reduce the amount of time it takes for network changes, additions, and moves to be implemented. Notes when setting-up VLANs • A VLAN does not have a minimum number of port • VLANs work at the OSI Layer 2 • A VLAN can be created per unit, device or via logical connection/combination • Broadcast and Multicast traffic is transmitted only in the VLAN in which traffic is generated. • To allow traffic between VLAN a device working at protocol level (Layer 3) is required GSM7xxx - Shared access to the Internet across Multiple Routing VLANs using a Prosafe Firewall 192.168.2.x/24 DG 192.168.2.254 VLAN2 192.168.2.1/24 192.168.3.x/24 DG 192.168.3.1 VLAN3 192.168.3.1/24 192.168.4.x/24 DG 192.168.4.1 VLAN4 192.168.4.1/24 ____ VLAN 2: Ports 0/1 - 0/8 PVID = 2 DHCP = 192.168.2.0/24 ____ VLAN 3: Ports 0/21 - 0/28 PVID = 3 DHCP = 192.168.3.0/24 ____ VLAN 4: Ports 0/41 - 0/48 PVID = 4 DHCP = 192.168.4.0/24 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41T 43T 45T 47T 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42T 44T 46T 48T M1 M2 M3 M4 41T 43T 45T GSM7352S 47T 42T 44T 46T 48T Default IP route : 192.168.2.254 DGFV338 Static routes: 192.168,3.0 255.255.255.0 192.168.2.1 192.168.4.0 255.255.255.0 192.168.2.1 192.168.2.254/24 ProSafe VPN Wireless ADSL Gateway MODEL DGFV 338 PWR TEST INTERNET 10 0 D SL LINK/ACT LOCAL 10 0 1 2 3 4 5 6 7 8 WLAN Link/ACT Internet 2
