General IP Routing
This chapter provides information on network functions including:
◆ Static Routes – Configures static routes to other network segments.
◆ Routing Table – Displays routing entries learned through statically configured
entries.
Overview
This switch supports IP routing and routing path management via static routing
definitions. When IP routing is functioning, this switch acts as a wire-speed router,
passing traffic between VLANs with different IP interfaces, and routing traffic to
external IP networks. However, when the switch is first booted, default routing can
only forward traffic between local IP interfaces. As with all traditional routers, static
routing must first be configured to work.
Initial Configuration
By default, all ports belong to the same VLAN and the switch provides only Layer 2
functionality. To segment the attached network, first create VLANs for each unique
user group or application traffic (
page 149 ), assign all ports that belong to the same
group to these VLANs ( page 152 ), and then assign an IP interface to each VLAN
( page 499 or page 503 ). 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 (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.
