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, first create VLANs
for each unique user group or application traffic (page 3-110), assign all
ports that belong to the same group to these VLANs (page 3-111), and
then assign an IP interface to each VLAN (page 3-155). 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.
