3. Determine which network res

ources must be shared by the subnets. Shared resources may be connected directly

utes to each of the shared resources should be determined.

n the network need more security or should be isolated from the other

subnets. IP or MAC filtering can be used. Also, one or more VLANs on the Layer 3 Switch can be configured

without an IP subnet – in which case, these VLANs will function as a layer 2 VLAN and would require an

6. Develop a policy scheme. Some subnets will have a greater need for multicasting bandwidth, for example. A

policy is a mechanism to alter the normal packet forwarding in a network device, and can be used to intelligently

function can be used to block

the redundant link until it is needed.

VLAN Setup

VLANs setup in Layer 3 Switching is more complicated than in conventional Layer 2 Switching environments. Be sure to

carefully plan the VLAN/IP interface arrangement for the network before configuring the VLANs and IP interface

VLANs configuration and concepts are provided in Part III.

4. Determine how each subnet will communicate with the WAN or Internet. Again, static routes should be

determined and default gateways identified.

5. Develop a security scheme. Some subnets o

allocate bandwidth to time-critical applications such as the integration of voice, video, and data on the network.

7. Develop a redundancy scheme. Planning redundant links and routes to network critical resources can save

valuable time in case of a link or device failure. The DGS-3312SR Spanning Tree

efining Static Routes

outes between the IP interfaces and a default gateway or other router with a WAN connection should be determined

eforehand and entered into the static/default routing table on the DGS-3312SR.
