Ip Routing; Overview; Initial Configuration - SMC Networks TigerStack II SMC8848M Management Manual

Overview

This switch supports IP routing and routing path management via static
routing definitions (page 17-26) and dynamic routing such as RIP
(page 17-30). When IP routing is enabled (page 17-31), this switch acts as a
wire-speed router, passing traffic between VLANs using different IP
interfaces, and routing traffic to external IP networks. However, when the
switch is first booted, no default routing is defined. As with all traditional
routers, the routing functions must first be configured to work.

Initial Configuration

In the default configuration, all ports belong to the same VLAN and the
switch provides only Layer 2 functionality. Therefore, you should first
create VLANs for each unique user group or application traffic (page
11-8), assign all ports that belong to the same group to these VLANs (page
11-10), and then assign an IP interface to each VLAN (page 17-7). By
separating the network into different VLANs, it can be partitioned into
subnetworks that are disconnected at Layer 2. Network traffic within the
same subnet is still switched using Layer 2 switching. And the VLANs can
now be interconnected (only as required) with Layer 3 switching.
Each VLAN represents a virtual interface to Layer 3. You just need to
provide the network address for each virtual interface, and the traffic
between different subnetworks will be routed by Layer 3 switching.
