CONFIGURING THE SWITCH

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.
